The brain and spinal cord are two components of the Central nervous system which are responsible for sensory information.

Strength of concrete increases with increase in water cement ratio as the strength of the cement is directly proportional to water cement ratio.

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.

The combined gas law states that the ratio between the pressure-volume product and the temperature of a system remains constant.

Hence it depends on all the three Volume, Temperature & Pressure.
