Some questions would be very simple unless we try to answer them. Every parent would have experienced it when their child asks so many simple questions which they do not know the answers though they have lived all their life seeing them. This article brings you the answers to such simple questions. Let’s see how many answers you know.
Why do onions make us cry?
Slicing through an onion rips open its cells, releasing various chemicals that react together. After about 30 seconds, a sulphur carrying gas is produced that mixes with the water in your eye, producing burning sulphuric acid. That’s what causes discomfort. The front of your eyeball called the cornea is packed with nerve endings to detect any physical or chemical irritants. They sense the chemical and send a signal to your tear glands to boost the production of tears to flush it away.
Why do we Yawn?
We yawn when your brain becomes a little hotter than it needs to be to work well. Yawning helps cool the blood on its way to our brain. It helps you feel more alert and focus better. It often happens at the moment you realise it is time for action after you’ve been sitting around not doing much.
Do Fishes die when lightning strikes the Sea?
Water conducts electricity so well, especially seawater. When lightning strikes the surface, a huge amount of electric charge lands in the sea. But the sea is big and the electricity can quickly spread out and get diluted. So it doesn’t affect the organisms underneath. But the fishes on the surface are more likely to be killed.
Why do mosquitoes only bite some people?
Mosquitoes have a powerful sense of smell and are attracted to chemicals we release from our bodies. One of them is carbon dioxide, and both women and larger people tend to breathe out more of this gas. The more that’s breathed out, the easier it is for mosquitoes to find you.
Why Are There So Many Languages in The World?
Thousands of years ago, people in different communities all over the globe invented their own words to describe their lives, and that’s why today people from the same area tend to speak the same language and other people may not.
Why your left hand appears as right in the mirror?
Mirrors don’t reverse left to right, they reverse front to back. Consider this, when you look at yourself in a mirror, it appears to you that your reflection is another person who looks just like you standing behind a piece of glass, at the same distance from the glass as yourself and facing you. To get there, you reason, that person walked behind the glass and – here’s the important bit – turned 180 degrees about the vertical axis to face you. Now his/her left hand should be opposite your right hand, and vice versa. In fact, this assumption is wrong. Your reflection didn’t do a 180-degree turn. It was reversed front to back with no rotation at all. Your brain mentally subtracts the 180-degree turn that you assume must have happened from the observed front-to-back reversal and what do you get? A clear left-to-right reversal. It is called lateral inversion.
