What is WATER?

What Is Water?
Have you ever heard someone refer to water as H2O? Why do you suppose someone might call water by this name? What is water? Water is a basic molecule made up of two hydrogen atoms and one oxygen atom. When these three atoms come together, they form a strong bond that is difficult to break. The strength of this bond keeps a water molecule together for millions and even billons of yeArs.

Water is one of the most common substances on the Earth. Covering over 70% of the surface of the Earth, it is easy to find.

Scientists believe that the amount of water on Earth does not change appreciatively over time. In other words, the amount of water that is on the Earth today is the same amount that was on the Earth during the reign of the dinosaurs.






What is ROM?

read-only memory (ROM)


ROM is "built-in" computer memory containing data that normally can only be read, not written to. ROM contains the programming that allows your computer to be "booted up" or regenerated each time you turn it on. Unlike a computer's random access memory (RAM), the data in ROM is not lost when the computer power is turned off. The ROM is sustained by a small long-life battery in your computer.

What is Mohenjo Daro The City of Mounds

City of Mounds
Archaeologists first visited Mohenjo Daro in 1911. Several excavations occurred in the 1920s through 1931. Small probes took place in the 1930s, and subsequent digs occurred in 1950 and 1964.
The ancient city sits on elevated ground in the modern-day Larkana district of Sindh province in Pakistan.
During its heyday from about 2500 to 1900 B.C. the city was among the most important to the Indus civilization, Possehl says. It spread out over about 250 acres (100 hectares) on a series of mounds, and the Great Bath and an associated large building occupied the tallest mound.
According to University of Wisconsin, Madison, archaeologist Jonathan Mark Kenoyer, also a National Geographic grantee, the mounds grew organically over the centuries as people kept building platforms and walls for their houses.
Prized Artifacts
A miniature bronze statuette of a nude female, known as the dancing girl, was celebrated by archaeologists when it was discovered in 1926, Kenoyer notes.
Of greater interest to him, though, are a few stone sculptures of seated male figures, such as the intricately carved and colored Priest King, so called even though there is no evidence he was a priest or king.
The sculptures were all found broken, Kenoyer says. "Whoever came in at the very end of the Indus period clearly didn't like the people who were representing themselves or their elders," he says.
Just what ended the Indus civilization—and Mohenjo Daro—is also a mystery.
Kenoyer suggests that the Indus River changed course, which would have hampered the local agricultural economy and the city's importance as a center of trade.
But no evidence exists that flooding destroyed the city, and the city wasn't totally abandoned, Kenoyer says. And, Possehl says, a changing river course doesn't explain the collapse of the entire Indus civilization. Throughout the valley, the culture changed, he says.

What is litmus paper

You can make paper test strips to determine the pH of an aqueous solution by treating filter paper with any of the common pH indicatorsOne of the first indicators used for this purpose was litmus. Litmus paper is paper that has been treated with a specific indicator - a mixture of 10-15 natural dyes obtained from lichens (mainly Roccella tinctoria) that turns red in response to acidic conditions. When the pH is neutral (pH = 7) then the dye is purple. The first known use of litmus was around 1300 AD by Spanish alchemist Arnaldus de Villa Nova. The blue dye has been extracted from lichens since the 16th century. The word "litmus" comes from the old Norse word for "to dye or color".

Litmus Test

To perform the test, simple place a drop of liquid sample on a small strip of paper or dip a piece of litmus paper in a small specimen of the sample. Ideally, you don't dip litmus paper in an entire container of a chemical.
The litmus test is a quick method of determining whether a liquid or gaseous solution is acidic or basic.

Limitations of the Litmus Test

The litmus test is quick and simple, but it suffers a few limitations. First, it's not an accurate indicator of pH. It does not yield a numerical pH value. Instead, it roughly indicates whether a sample is an acid or a base. Second, the paper can change colors for other reasons besides an acid-base reaction. For example, blue litmus paper turns white in chlorine gas. This color change is due to bleaching of the dye from hypochlorite ions, not acidity/basicity.



What is LAW?

Explaining the terms “Law” and “Morality” or "Justice".
When discussing law and morality or law and justice, it is important to define the terms, from the below you will probably decide it is not possible to define what law IS, but it is possible to describe what it does and what rules apply. This is essentially a philosophical question, which probably has no answer, but some theorists have attempted to do so.

Similarly, there is no agreement what morality IS, or justice IS and there are various “schools” of thought.

What is “Law”?
It is possible to describe law as the body of official rules and regulations, generally found in constitutions, legislation, judicial opinions, and the like, that is used to govern a society and to control the behaviour of its members, so Law is a formal mechanism of social control.


Advantages of Guava

Benefits Of Guava

The health benefits of guava include the treatment of diarrhea, dysentery, constipation, cough, cold, skin care, high blood pressure, weight loss and scurvy.
Many of you may have tasted this mouth-watering treat, or have at least seen or heard about it. Guava is very common in Asian countries, but is increasingly available in the western world, particularly as more of its health benefits are revealed. It is a somewhat round or pear-shaped seasonal fruit, and is light green, yellow, or maroon in color on the outside when it is ripe. Guava also has white or maroon flesh and lots of small hard seeds enveloped in very soft, sweet pulp. It is eaten raw (ripe or semi-ripe) or in the form of jams and jellies.

Health Benefits Of Guava


Some of the surprising and brilliant health benefits are listed below.
Weight loss: Guava is very helpful for those who want to lose weight without compromising their intake of proteinsvitamins and fiber. Guava is very high in roughage and rich in vitamins, proteins and minerals, but it has no cholesterol and a low number of digestible carbohydrates. It is a is very filling snack and satisfies the appetite very easily. Guava, especially raw guava, also has far less sugar as compared to apples, oranges, grapes, and other fruit. Adding a medium-sized guava to your lunch and you will not feel hungry again until the evening. Ironically, it can also help with weight gain in lean, thin people. This is probably due to its wealth of nutrients, which keep the metabolism regulates and helps to promote the proper absorption of nutrients.
DiabetesIn a related benefit to blood pressure mentioned above, an intake of guava can also help those patients who suffer fromdiabetes. The high level of dietary fiber in guava helps to regulate the absorption of sugar by the body, which decreases the chances of major spikes and drops in insulin and glucose in the body. Studies have shown that consuming guava can help prevent the appearance of type-2 diabetes.
Cancer Prevention: One of the most celebrated and important benefits of adding guava to your diet is its ability to inhibit the growth and metastasis of cancerous cells. There have been numerous studies done in recent years on guava’s effects primarily on prostate cancerbreast cancer, and oral cancers. Guava leaf oil is extremely successful as an anti-proliferative substance, and has actually been shown to be more effective than some leading modern medicines in reducing cancerous growth. Guavas are also rich in lycopene, a powerful antioxidant that has been shown to be wildly successful in reducing prostate cancer risk. That same antioxidant has also shown to inhibit the growth of breast cancer cells, although further human trials need to be done.

Advantages of Travelling

Wonderful Benefits Of Traveling

1. You will find a new purpose

“To travel is to take a journey into yourself.” – Danny Kaye
Traveling is an amazingly underrated investment in yourself. As you travel you’re exposed to more new people, cultures, and lifestyles than you are living in your homeland all the time. With all the newness in your life, you’re also opened to new insights, ways of seeing the world and living, which often gives people a new purpose for their lives. If you’re feeling stuck on what your purpose is, what you want to do with your life, the career or educational path you want to pursue, go travel…you might just be surprised about what you discover as a new sense of life purpose and direction.

2. You will appreciate your home more

When we spend time away from home, especially in a place where we don’t have the same luxuries readily available to us…like a village in Fiji that runs without electricity…we become more aware and appreciative for the luxuries we have back at home. I remember a time where I visited my cousin in Argentina after she’d been living there for about a year. I was visiting her around Christmas time and brought her the new Harry Potter book along with some basic goods that you can find almost anywhere in Los Angeles. She was over joyous and filled with gratitude, like she just got the greatest gift in the world. In other parts of the world, like India and Ethiopia, people don’t have as much access to clean drinking water…especially from what’s readily available on tap. Traveling through areas like that really make us appreciate what we do have, and often can spark the movement of something to support people living there experience a greater quality of life.

3. You will realize that your home is more than just where you grew up

“No one realizes how beautiful it is to travel until he comes home and rests his head on his old, familiar pillow.” – Lin Yutang
The more we travel, the more we realize that our home is so much more than the town, city, state and even country that we’ve grown up in; we realize that our home is the world, this planet, and we become more conscious of how we can harmoniously live and support one another. And in that knowingness and state of consciousness, people like those supporting the movement of charity:water come into fruition.

4. You will realize how little you actually knew about the world

“The world is a book, and those who do not travel read only one page.” – Saint Augustine
There’s concept, and then there’s experience. When we travel, we may notice that some of the things we’ve heard about the world end up being very different than what we were indoctrinated and conditioned to believe. Many of the initial myths that get dispelled are often about traveling itself. Where you once may have thought it was too expensive and dangerous, you may realize how you can actually save more on your lifestyle expenses traveling the world than you do living at home.

5. You will realize that we all share similar needs

“Travel is fatal to prejudice, bigotry, and narrow-mindedness.” – Mark Twain
Tony Robbins has said many times that no matter what your background is, all human beings share 6 common needs. As you travel more, you notice the truth of this even more…and as that happens, you are more adept in being able to relate to people regardless of their background.

Advantages & Benefits of Zeera

Benefit 1: Improves digestion

The presence of thymol and other essential oils in cumin seeds stimulate the salivary glands thereby helping in the digestion of  food. Apart from this, it strengthens a sluggish digestive system.

Tip: Add a teaspoon of cumin seeds to a glass of water and bring it to a boil. Once the water turns brown, turn off the gas and cover the vessel. Allow the decoction to cool down to room temperature. Drink this tea three times a day to improve digestion and to help resolve minor stomach aches. If you want the tea to be a little mild, you can add some cumin seeds to a glass of boiling hot water and cover it. Let it steep and then decant the water.

Benefit 2: Beats constipation

Due to its high fibre content, jeera boosts the activity of the gastrointestinal tract which in turn stimulates enzyme secretion. This is why jeera powder is commonly  used as a  natural laxative. In fact, its laxative properties are so powerful that Ayurveda practitioners believe that it is capable of preventing and healing severe digestive disorders like piles.

Tip: To get relief from constipation, roast jeera seeds on a tawa till they turn deep brown. Now, cool them and grind them into a fine powder. Mix this powder with water or honey and consume it on an empty stomach. Another good remedy is to have some freshly prepared jeera tea.

Benefit 3: Fights cancer
According to the studies conducted by the Cancer Research Laboratory of Hilton Head Island, South Carolina, USA, jeera can help in the fight against cancer. This is because it contains an active compound, known as cuminaldehyde that helps in retarding the growth of tumours. However, this  anti-cancer property was confined to kala jeera.

Tip: Don’t forget to add a pinch of jeera to your dal as seasoning or sprinkle few seeds over a gravy to reap its benefits.

Advantages of Garlic

Grow beautiful hair with garlic.

Garlic could end your hair loss problems because of its high levels of allicin, a sulfur compound similar to that found in onions, which were found to effectively treat hair loss. Rub sliced cloves of garlic on your scalp, squeezing as you go for the most benefit. You can also infuse oil with garlic and massage it into your scalp.


Garlic clears acne.

It might not be a main ingredient in your drugstore acne medication, but garlic makes a great natural remedy to banish unsightly blemishes. Its antioxidants kill bacteria, so rub a sliced clove of garlic on the pimple for an effective topical treatment.

Garlic prevents and treats colds.


Packed with antioxidants, a daily dose of garlic in your recipes could benefit your immune system.

Soothe psoriasis with garlic.

Since garlic has proven anti-inflammatory properties, it could be useful in relieving uncomfortable psoriasis outbreaks. Try rubbing a little garlic oil on the affected area for smooth, rash-free skin.

Control your weight with garlic.

Garlic could help you control your weight, according to nutritionist Cynthia Sass, who cites a study that showed mice eating a garlic-rich diet reduced their weight and fat stores. To take advantage of this benefit, try to cook with garlic daily.

Advantages Solutions of Soil

Soil fertility is the foundation of crop production and involves complex interactions between soil, nutrients and plants. Factors affecting soil fertility such as texture and bioavailability of plant nutrients should be optimized to improve yield and quality of crops. Soil management is thus critical to sustain soil productivity over time.
With continuous land cropping, soil depletion is widespread due to intense land cultivation and inadequate soil management. Soil depletion can occur through overtillage that damages soil structure, overuse of chemical fertilizers that inhibit microorganisms, and salinization of soil. Agricultural land with damaged soil impedes root penetration and reduces crop yield, causing the grower to lose economic value.
Our Soil Advantage Solutions concurrently enhance soil fertility through organic matter, maximize nutrient absorption by plants through bioavailable plant nutrients and improve soil texture through microbes. The technology applied derives organic matter from readily available compost and fortifies it with plant nutrients derived solely from renewable and recycled sources.

Advantages & Disadvantages of Coal

ADVANTAGES OF COAL ENERGY

1.Coal energy is very affordable due to its stable price unlike any other forms of energy in the market.
2. The abundance of coal energy is in a large number.
3. It is also easy to burn.
4. Coal energy is a renewable form of energy.
5. Reliability is entailed and presented in this form of energy.
6. Aside from its reliability, coal energy is also inexpensive unlike any other sources of energy.
7. This form of energy is producing high energy upon its combustion process.
8. The power generation scale of coal is great that makes it possible for building a range of sizes of generation plants.

DISADVANTAGES OF COAL ENERGY

1. Coal energy is producing tremendous amount of carbon emissions that results in climate change and global warming.
2. Coal burning is considered not environmental friendly due to the production of harmful by-products like nitrogen, carbon dioxide and sulfur dioxide.
3. Coal burning can cause pollution to the environment like acid rain.
4. Coal energy is fast depleting because many people consume a large amount of it inefficiently.
5. This form of energy is not a renewable one.
6. It is also ruining the ecosystem and environment and putting many people’s lives in danger especially miners.
7. Underground mining is very hazardous because cave-ins and explosions are common.

Advantages & Disadvantages of Partnership

Advantages of Partnership

  • Capital – Due to the nature of the business, the partners will fund the business with start up capital. This means that the more partners there are, the more money they can put into the business, which will allow better flexibility and more potential for growth. It also means more potential profit, which will be equally shared between the partners.
  • Flexibility – A partnership is generally easier to form, manage and run. They are less strictly regulated than companies, in terms of the laws governing the formation and because the partners have the only say in the way the business is run they are far more flexible in terms of management, as long as all the partners can agree.
  • Shared Responsibility – Partners can share the responsibility of the running of the business. This will allow them to make the most of their abilities. Rather than splitting the management and taking an equal share of each business task, they might well split the work according to their skills. So if one partner is good with figures, they might deal with the book keeping and accounts, while the other partner might have a flare for sales and therefore be the main sales person for the business.
  • Decision Making – Partners share the decision making and can help each other out when they need to. More partners means more brains that can be picked for business ideas and for the solving of problems that the business encounters.
Disadvantages of Partnership

  • Profit Sharing – Partners share the profits equally. This can lead to inconsistency where one or more partners aren’t putting a fair share of effort into the running or management of the business, but still reaping the rewards.
      * Disagreements – One of the most obvious disadvantages of partnership is the danger of         disagreements between the partners. Obviously people are likely to have different ideas on how the business should be run, who should be doing what and what the best interests of the business are. This can lead to disagreements and disputes which might not only harm the business, but also the relationship of those involved. 

  • Agreement – Because the partnership is jointly run, it is necessary that all the partners agree with things that are being done. This means that in some circumstances there are less freedoms with regards to the management of the business. Especially compared to sole traders. However, there is still more flexibility than with limited companies where the directors must bow to the will of the members.
  • Liability – Ordinary Partnerships are subject to unlimited liability, which means that each of the partners shares the liability and financial risks of the business. Which can be off putting for some people. This can be countered by the formation of a limited liability partnership, which benefits from the advantages of limited liability granted to limited companies, while still taking advantage of the flexibility of the partnership model.

Advantages & Disadvantages of Dams

Important Advantages of Dams

ADVANTAGES: 
1. Once a dam is constructed, electricity can be produced at a constant rate.

2. Dams are designed to last many decades and so can contribute to the generation of electricity for many years / decades. 

3. If electricity is not needed, the sluice gates can be shut, stopping electricity generation. The water can be saved for use another time when electricity demand is high. 

4. The lake that forms behind the dam can be used for water sports and leisure / pleasure activities. Often large dams become tourist attractions in their own right.

5. The lake's water can be used for irrigation purposes.  

DISADVANATGES:
1. Dams are extremely expensive to build and must be built to a very high standard. 

2. The high cost of dam construction means that they must operate for many decades to become profitable.

3. People living in villages and towns that are in the valley to be flooded, must move out. This means that they lose their farms and businesses. In some countries, people are forcibly removed so that hydro-power schemes can go ahead.
4. The flooding of large areas of land means that the natural environment is destroyed.

5. Building a large dam alters the natural water table level. For example, the building of the Aswan Dam in Egypt has altered the level of the water table. This is slowly leading to damage of many of its ancient monuments as salts and destructive minerals are deposited in the stone work from rising damp caused by the changing water table level. 

How to drive a car easily

Dirve Care Easily


1) Adjust the seat so that your feet comfortably reach both pedals. You can adjust your seat forward and backward, as well as up and down. Some cars will have electronic controls  while older cars will usually have a latch underneath the seat that let's you control the position of the seat. But you can tell the difference.


2) Familiarize yourself with the foot pedals. In an automatic car, the two foot pedals control acceleration and braking, respectively. The rightmost pedal (which is usually smaller than the other pedal) is the acceleration pedal, and pressing down on it speeds the car up. The pedal to the left (which is usually larger than the acceleration pedal) is the brake pedal, and pressing down on it slows the car down.
  • Even if you are left-foot dominant, use your right foot to reach both pedals. It will feel weird at first if you're left-footed, but getting used to it is important because it's proper technique and ultimately safer.
  • Never use both feet at once to reach the pedals. Only use one foot — your right foot — to access each pedal. This will make it impossible to accidentally press down on both pedals at the same time.
3) Adjust your car's mirrors so that you can see through them clearly and effectively. Your car should have three mirrors: one rear view mirror, which allows you to see directly behind the rear windshield in back of you, and two outside mirror which let you see to either side of the car and protect you from blind spots.
  • Your rear view mirror should be positioned so that when you're in your normal driving position, you can see directly behind you and as much of the rear windshield as possible.
  • The Society of Automotive Engineers has one recommendation for how to position your outside mirrors in order to eliminate blind spots. It recommends positioning the mirrors further outward than normal, so that they just overlap with the viewing angle of the rear view mirror.[2] Although disorienting at first, this positioning actually clues the driver in to cars in her blind spots which she might otherwise only be able to spot by looking over her shoulder.

4) Know where the parking brake, also called a hand or emergency brake, is and what it does. The parking brake is a longer lever with a button on its very tip. When the parking brake is pulled up, it helps locks the car in place, ensuring that it doesn't move. When the brake is let down, it is disengaged and the car can freely move. Make sure that your parking brake is disengaged before you start driving.

5) Get a feel for the shift lever. The shift lever is usually positioned in between the two front seats of a car, and it controls some of the car's gears (park, neutral, drive, reverse). Sometimes, the shift lever is on the right side of the steering wheel.
  • If your shift lever is engaged in Park and you turn your car on, your car won't move forward no matter how much you press down on the acceleration.
  • If your shift lever is in Neutral, your car's natural momentum will continue to carry it forward.
  • If your shift lever is in Reverse, your car will move backwards instead of moving forwards when you take your foot off the brake.
  • If your shift lever is in Drive, your car will move forwards when you take your foot off the brake.6
6) Understand your basic dashboard controls. These gauges help show the driver how much gas the car is carrying, how fast the car is going, how hot the engine is, and how many RPM (revolutions per minute) the engine is clocking.
  • The speedometer is probably the most important dashboard control in the car. It tells you how fast your car is traveling, in either miles per hour (MPH) or kilometers per hour.
  • The RPM gauge tells you how hard your engine is working. Most RPM gauges will have red areas starting at 6,000 or 7,000 RPM. When the dial in the gauge, travels into the red, learn to ease off the acceleration.
  • The gas gauge tells you how much fuel your car has. It usually has a dial that travels between "F" and "E," with "E" signaling "empty" and "F" signaling "full."

How to make fast Pizza

Fast Pizza

1) Preheat the oven to 400° Fahrenheit (204°Celsius). The oven should be piping hot before you start cooking the pizza.


2) Prepare the crust. Remove the unbaked crust from the packaging. Place it on a round or rectangular baking sheet, depending on what you have on hand. Use a pastry brush to spread a thin coating of olive oil over the top of the crust.

3) Spread pizza sauce on the crust. How much pizza sauce you add is purely a matter of personal preference. If you love a lot of sauce, go ahead and slather it on. If you prefer your pizza on the dry side, spoon a little in the middle and spread it around in a thin layer.
  • If you want to make a white pizza, add a little extra olive oil and skip the pizza sauce.
  • You can make a quick pizza sauce using tomato paste, a can of diced tomatoes, and some spices. Simmer the paste and tomatoes together over low heat. Add salt, oregano and pepper to taste. Continue simmering until the sauce cooks down to the consistency of pizza sauce.
