General Science Questions

Our atmosphere is made up of

78% Nitrogen,

21% Oxygen and

1% all other gases like argon, carbon dioxide, neon, and helium.

So, Nitrogen makes up the majority of our atmosphere.

C3 plants are plants that undergo C3 photosynthesis, which means that they undergo the Calvin cycle (converting carbon dioxide into energy) in their chloroplasts and typically keep their stomata open during the day. These are the most common types of plants.

In C3 plants the conservation of water promotes Photorespiration.

Most producers use sun light for making their energy in the process of photosynthesis. The energy they prepared is sugar and glucose. 

Secondary succession means in an ecosystem renewal of itself after all or a portion has been destroyed.

After a forest fire, the whole forest had destroyed but after that again renewal of that forest is also an example of secondary succession.

Water reabsorption by the renal tubules is harmonally controlled and it is a osmosis mechanism.

Cobalt therapy or cobalt-60 therapy is the medical use of gamma rays from the radioisotope cobalt-60 to treat conditions such as cancer.

Cobalt 60 is a synthetic radioactive isotope of cobalt with a half-life of 5.2714 years. It is produced artificially in nuclear reactors.
