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.

The troposphere is the lowest layer of the Earth's atmosphere. The air is very well mixed and the temperature decreases with altitude. Air in the troposphere is heated from the ground up. The surface of the Earth absorbs energy and heats up faster than the air does.

Kingdom is the smallest level of classification.

The level of classification from largest to smallest is :

* Domain

* Kingdom

* Phylum

* Class

* Order

* Family

* Genus

* Species

A daisy-wheel printer works on the same principle as a ball-head typewriter. Daisy wheel printer is a type of impact printer invented in 1969.

The daisy wheel is a disk made of plastic or metal on which characters stand out in relief along the outer edge. To print a character, the printer rotates the disk until the desired letter is facing the paper.

A protein that acts as a hormone is INSULIN.

Insulin is a peptide hormone produced by beta cells of the pancreatic islets; it is considered to be the main anabolic hormone of the body.  Insulin helps keeps your blood sugar level from getting too high or too low.  

Photosynthesis is a process used by plants and other organisms to convert light energy into chemical energy that can later be released to fuel the organisms activities.

Climatology is a study of climate which is subspecialty of environmental science studies.
