What is photosphere?

Photosphere is the outer shell of star from which light is radiated.

It is the innermost layer of the solar atmosphere to which our eyes can penetrate through the superficial transparent layers.

Our view is obstructed beyond this layer by the rapidly increasing opacity of the denser layers of the gas as we go inward through it.

Temperature of photosphere for Sun is about 5,800 K and values of pressure & density are low.

How does potash alum arrest bleeding?

Bleeding can be stopped by coagulation of the blood (formation of a clot). Potash alum has highly charged Al3+ and (SO4)2- ions which act as neutralizing ions for the protein colloid in blood.

This causes aggregation or clotting and this in turn stops the bleeding.
Chemical Formula of Potash Alum :
K2SO4.Al2(SO4)3.24H2O

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.

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.

What is TX- 2 initiative?

Double the number of Tigers by 2022.

Tigers are the largest species of cat and one of the most iconic animals on the planet.

One hundred years ago, there were 100,000 wild tigers.


By the year 2010, as few as 3,200 wild tigers remained.


This shocking 97% population decline was driven by rampant poaching and habitat loss. In 2010, governments of the 13 tiger range countries decided innovative conservation efforts were needed.

The most ambitious and visionary species conservation goal was set: to double the number of wild tigers by 2022 – the next Chinese year of the tiger.


The goal is called Tx2 running by WWF.

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.
