General Science Questions

Exercise is a subset of physical activity that is planned, structured and repetative.

Vitamin B12 is the only water-soluble vitamin that can be stored in the liver for many years. There are 9 water soluble vitamins.

Photoautotrophs are those organisms that can make their own food using sun light with the help of the process of photosynthesis.

Plants can prepare their own food using sunlight. Hence they are Photoautotrophs.

In the process of photosynthesis, plants need the sun's energy, water to make food for themselves in the form of ATP ( adenosine triphosphate ) , which is packages of energy.

Carbon :

coming into the plants ( or algae ) along with water make those ATP into a bigger molecule, which is know as glucose.

Formula: 6 CO2 + 6 H2O + Suns Energy -> glucose + oxygen

Photosynthesis has an affect on the carbon cycle because it reduces the amount of CO2 in the air and redirects it into sugars which feeds animals as well as humans.

Hence, Photosynthesis removes CO2 from the atmosphere and replaces it with O2.

We know that, 

Earth is known as Watery planet.

Neptune is known as Blue planet. 

Chemically marble is known as Calcareous rock as it is composed of carbonate minerals like calcite or dolomite.
