288. Why do fingers and toes wrinkle when left in water?

According to Mark Changizi, a theoretical neurobiologist the wrinkling was caused by the constriction of multiple blood vessels beneath the skin and is the result of an involuntary nervous system reaction. But a century ago, scientists already knew that this curious reaction wasn't a simple reflex or the result of osmosis. That’s because surgeons learned that if certain nerves to the fingers were cut, the wrinkling response would disappear. Wrinkled fingers, then, are signs of an intact nervous system. Indeed, the wrinkling response has been suggested as a means of determining whether the sympathetic nervous system is functional in patients that are otherwise unresponsive. Mark Changizi came across a bunch of studies starting in the 1930s and going through the 2000s that showed that if the nerves that fed the hands had been damaged, fingers would not wrinkle after being soaked in water. And he thinks more research is needed to validate why.

289. Why are things related to the moon referred to as 'lunar'?

The word 'lunar' comes from 'Luna' who was Roman goddess of the Moon. In works of art she is represented as a beautiful young maiden, wearing a short hunting dress, and carrying a bow, a quiver full of arrows and a crescent on her forehead. Luna protected crops and drove across the sky at night in a chariot. To explain moonless nights, the Romans claimed that Luna had fallen in love with a mortal shepherd named Endymion and had left the sky to visit him. Did you know that the word 'lunatic' is also derived from 'Luna'? This is because in ancient times it was believed that strange or odd behavior was caused by the Moon!

317. How do the seasons work?

Earth has seasons because our planet's axis of rotation is tilted at an angle of 23.5 degrees relative to our orbital plane – the plane of Earth's orbit around the sun. The tilt in the axis of the Earth is called its obliquity by scientists.
The tilt of the Earth means the Earth will lean towards the Sun (Summer) or lean away from the Sun (Winter) 6 months later. In between these, Spring and Autumn will occur. The North pole always points the same way as the Earth revolves around the Sun. The Earth's movement around the sun causes the seasons.

324. How do one way mirror work ?

A one-way mirror has a reflective coating applied in a very thin, sparse layer -- so thin that it's called a half-silvered surface. The name half-silvered comes from the fact that the reflective molecules coat the glass so sparsely that only about half the molecules needed to make the glass an opaque mirror are applied. At the molecular level, there are reflective molecules speckled all over the glass in an even film but only half of the glass is covered. The half-silvered surface will reflect about half the light that strikes its surface, while letting the other half go straight through.

An aurora is a natural light display in the sky, predominantly seen in the high latitude regions (Aurora Borealis or the Northern Lights and Aurora Australis or the Southern Lights). The aurora is formed when charged particles emitted from the sun during a solar flare penetrate the earth's magnetic shield and collide with atoms and molecules in our atmosphere. These collisions result in countless little bursts of light, called photons, which make up the aurora. Collisions with oxygen produce red and green auroras, while nitrogen produces the pink and purple colors.

370. What part of the body does not have a blood supply?

The only living cells in the body that aren't directly served by blood vessels are those of the cornea in the eye. Oxygen and nutrients instead diffuse directly from the tear fluid on the outside and the aqueous humour (the thick watery substance between the lens and the cornea) on the inside, as well as along the nerve fibres that are connected to the cornea. One of the problems with contact lenses is that they reduce the oxygen supply from the outside. Even with gas-permeable lenses, this can cause corneal neovascularisation, where blood vessels grow into the cornea. This problem is reduced or eliminated by the newest silicone hydrogel lenses. As well as the cornea, other areas of the body that don't have blood vessels include hair, nails, tooth enamel and the outer skin layers.

372. What is the white, powdery substance that forms on battery ?

The white powdery substance is sulfuric acid and hydrogen crystals from the escaping hydrogen battery gases and liquid (the batteries have vents that allow the gases to escape.) This acid causes corosion of the copper wires and steel bolts attached to the battery and to some degree the battery posts and post connectors which are made of lead.

373. Why plants bent toward lights?

The higher concentration of auxin on the shady side causes the plant cells on that side to grow more so it bends toward the light. Because light is the energy source for plant growth, plant shave evolved highly sensitive mechanisms for perceiving light.
It is called phototropism. Not all plants bend towards light. Monstera and Philodendron, are instead negatively phototropic and direct their stems towards the shadow cast by tree trunks, which these vines need for support.

375. Male mosquito feeds on ?

Only female mosquitoes bite. Both male and female feed mainly on fruit and plant nectar, but the female also needs the protein in blood to help her eggs develop. Once she's had her fill of blood, she'll rest for a couple of days before laying her eggs.

376. What is Moonbow? How is it different from rainbow?

A moonbow  is a  rainbow produced by  moonlight rather than sunlight. Other than the difference in light source, its formation is exactly the same as for a solar rainbow: It is caused by the refraction of light in many water droplets, such as a rain shower or a waterfall, and is always positioned in the opposite part of the sky from the moon relative to the observer.

377. How does E.C.G. work ?

Small metal disks called electrodes are placed on your skin. The electrodes are used to pick up the electrical impulses of the heart. The impulses are recorded, giving doctors a record of your heart's electrical activity. The electrodes have wires called leads, which hook up to the electrocardiogram machine (E.C.G.).

379. Why do animals have tails?

Many animals, such as felines,mammals and insects have tails. The tail has many functions. In Africa animals have evolved into growing tails to brush away flies. It is also used for balance, by animals such as cats and kangaroos.
Although, the Arctic Fox uses it's tail for warmth, and the fish uses it to move through water. It is very peculiar that animals have gotten to use tails in ways you would never would have predicted. Some fish also use it to inject venom into their prey, thus bringing the conclusion that tails have evolved to defend, attack and even warm the animal itself.

384. What is a carat, and how does it relate to a karat ?

A carat is a unit of weight for diamondsand other gemstones. One carat equals 200 milligrams (0.200 grams). There are 453 grams in a pound (1,000 grams to a kilogram).
A karat, when used with gold, is a unit of purity- 24-karat gold is pure gold, but usually you mix gold with a metal like copper or silver to make jewelry (because pure gold is too soft). Each karat indicates 1/24th of the whole. So if a piece of jewelry is made of metal that is 18 parts gold and 6 parts copper, that is 18-karat gold.
