What causes acid in human body ?

Our stomach is a highly acidic environment. This is important to help digestion by breaking the bonds linking amino acids.

If it hails and doesn't stop will it be the beginning of an ice age.

Not if this lasts for only a few years. The ice age was a period of extreme temperature reduction lasting an epoch.

Is it possible to discover a cure to destroy cancerous cells and preserve persons lives?

We are very close to achieving such a cure, although we can only answer that question, if and when we achieve such a cure.

What can I do as a student to help the planet in all kinds of situations?

We have all heard on the situation that our world is in, due to global warming. We can certainly all do our bit, by seperating trash, limit the use of single-use plastic and use our bicycle to go somewhere.

How do you calculate the number of neutrons and protons?

You can simply subtract the atomic number from the mass number in order to find the number of neutrons.

Remember!
1. Your mass number is the total number of neutrons and protons within the atom.
2. Your atomic number is the amount of protons within the atom.
3. For neutral atoms, the electron number is the same as the atomic number.

How does the placibo effect work?

A placebo is a substance with no known medical effects, such as sterile water, saline solution, or a sugar pill.... The expectations of the patient play a significant role in the placebo effect; the more a person expects the treatment to work, the more likely they are to exhibit a placebo response.

How far can electricity travel through water and does it make a difference in salt water or fresh water?

This all depends on the sources of electric potential.

It makes some difference whether the water is fresh or salt, but maybe not as much as you might think. Absolutely pure water is a pretty good insulator. But water is very hard to keep absolutely pure, and as soon as you have any ionic compounds such as salt in water, the ions will be available to conduct current.

What are the differences between the 3 main nutrients?

The three essential nutrients include carbohydrates, protein, fat, vitamins, minerals and water.

Carbohydrates

Carbohydrates are the main energy source for the brain. Without carbohydrates, the body could not function properly. Sources include fruits, breads and grains, starchy vegetables and sugars. Make at least half of the grains you consume whole grains. Whole grains and fruit are full of fiber, which reduces the risk of coronary heart disease and helps maintain normal blood glucose levels.

Protein

Protein is the major structural component of cells and is responsible for the building and repair of body tissues. Protein is broken down into amino acids, which are building blocks of protein. Nine of the 20 amino acids, known as essential amino acids, must be provided in the diet as they cannot be synthesized in the body. Ten to 35 percent of your daily calories should come from lean protein sources such as low-fat meat, dairy, beans or eggs.

Fat

Fat is an energy source that when consumed, increases the absorption of fat-soluble vitamins including vitamins A, D, E and K. Twenty to 35 percent of your daily intake should come from fat. Choose healthy options such as omega-3-rich foods like fish, walnuts and vegetable-based oils. Omega-3s help with development and growth. Limit intake of saturated fats such as high-fat meats and full-fat dairy. Other smart choices include nuts, seeds and avocado.

Given that in summer it is much hotter than in winter and thus water evaporates quicker, how come it rains less than in winter?

This all depends on the sources of electric potential.

What is a dimension?

A dimension is a measurable extent of a particular kind, such as length, breadth, depth, or height.

Is a water molecule wet?

Wetness is a property that only exists at larger scales. Individual water molecules can't be liquid, solid or gas either. That also requires the presence of multiple molecules. ... Water makes other things wet, it is not wet itself.

How is a rechargeable battery created?

As with all batteries, rechargeable batteries consist of an anode, a cathode, and an electrolyte. During charging, the anode material is oxidized, producing electrons, and the cathode is reduced, consuming electrons. ... These electrons constitute the current flow in the external circuit.

What happens at the center of the earth?

Just getting to the center of the Earth and surviving is impossible. The Earth's core is about 9,000°F—as hot as the sun's surface—and would instantly roast anyone who found himself there. Then there's the pressure, which can reach roughly three million times that on the Earth's surface and would crush you.

How does one become a scientist?

Earn a bachelor's degree and a master's degree in the field of science that interests you. It will also be very beneficial if you earn a doctorate in your field. Get experience in your field by shadowing other scientists. This will give you practical experience and will let you learn what it's like to be a scientist.

Why does the bitcoin exist?

Bitcoin was invented in 2008 by an unknown person or group of people using the name Satoshi Nakamoto and started in 2009 when its source code was released as open-source software. Bitcoins are created as a reward for a process known as mining. They can be exchanged for other currencies, products, and services.

How can I stop global warming as a student?

Turn off the lights.
Close doors immediately so heat does not escape.
Take short showers.
Walk or bike if you can (instead of having your parents drive you).
Turn off your computer when not in use (don't leave it on just to keep Facebook or Myspace active).

How does the brain communicate with other organs and cells in our body?

The average human brain contains about 86 billion nerve cells, called neurons. These are the building blocks of your brain. Neurons communicate with each other by sending chemical and electrical signals. ... Electrical impulses travel through neurons.

For how long can a human survive in space?

90 seconds!

After another minute, you'd be dead by asphyxiation. There is some good news to take away from this morbid message. You can likely survive unprotected in space for as long as 90 seconds, which is plenty of time to be rescued!

Why is Bitcoin popular?

The first and foremost reason is anonymity. Bitcoin allows users to send money to any place in the world at minimum costs and that in itself is an achievement.

Will bitcoin became our money in the future?

Though the concept came was introduced a few years ago, a common doubt that arises in most of our minds is "What is cryptocurrency"? Cryptocurrency is a type of digital asset, which is a medium of exchange in different types of transactions using cryptography. This medium of exchange also helps in controlling the creation of additional currency units. Though there has been a lot of talks and press releases about cryptocurrency, not many people and businesses are aware of this concept. It is important that more and more people become aware of the impact of cryptocurrency and its uses.

How is the bitcoin safe to use, and can you buy all the things with it? Can you go into a shop and buy with the bitcoin?

Why does vinegar react with baking soda?

Baking soda and vinegar react with each other because they exchange atoms. ... In this reaction, baking soda acts as a base, and takes a proton from vinegar, which is an acid. The reaction releases gas because when the baking soda receives the proton, it transforms into water and carbon dioxide.

What will happen to the Earth in 1 million years? Will everything change?

In the year 1 million, Earth's continents will look roughly the same as they do now and the sun will still shine as it does today. But humans could be so radically different that people today wouldn't even recognize them, according to a new series from National Geographic.

The National Geographic Channel series "Year Million" investigates what humans might look like far into the future. In six episodes, the show explores the possibility of merging technology with the human body, the potential to drastically extend lifespans, the effects of virtual reality, the use of computers to merge human minds, the availability of new sources of energy and the possibilities of spreading humanity into outer space.

They say that glass is neither a solid, nor a precise liquid. It is kind of a very slow moving liquid. How was this found out and why is it not classified as a solid?

Glass is not a slow-moving liquid. It is a solid, albeit an odd one. It is called an amorphous solid because it lacks the ordered molecular structure of true solids, and yet its irregular structure is too rigid for it to qualify as a liquid.

If we were to be sucked in a black hole how long would it take for the earth or galaxy to reach the end of the black hole which is a white hole?

The answer is surprising because you get a different one depending on whom you ask. You, as the faller, would experience a reality very different from what I, as an observer from the outside, would see. So, if we can’t agree, what do we think happens to you?

First, let’s clear up a common misconception. Black holes get a bad reputation for sucking in their surroundings, like some sort of cosmic vacuum cleaner. In reality, the gravitational pull of a black hole is the same of that for a regular star—just a lot stronger.

Why can certain apps and/or video games become addictive?

Many different causes factor into video game addiction. One of the main reasons that video games can become so addictive, however, is they are designed to be that way. Video game designers, like anyone else trying to make a profit, are always looking for ways to get more people playing their games. They accomplish this by making a game just challenging enough to keep you coming back for more but not so hard that the player eventually gives up.

Can we create rocket boots?

The problem with them is, like jetpacks, fuel. You simply can't cram enough fuel in a pair of boots — even massive platform boots — to get enough energy to fly more than a few seconds. ... Still, the big take-away here is that yes, rocket boots are possible.
