Vitamin A; it is a soluble vitamin in fatty bodies, which can not be released in the urine as other vitamins normally do, it is said that we consume large quantities in an inactive form since this is necessary for many human body processes such as vision, formation and maintenance of skin cells, the immune system, growth and even lactation and embryonic development, therefore it is not necessary to be active to consume large amounts of this vitamin.
Soil structure is important becuse it does affect the characteristic of soil.

Answer:
a) Because when we exercise, we hydrolyze more ATP to ADP and Pi, and O2 is necessary for the hydrolysis, so we increase our intake of oxygen.
c) Because when we exercise, we produce more CO2 and increased ventilation is necessary to rid ourselves of CO2.
d) Because when we exercise, we use more ATP, and additional O2 is necessary to generate sufficient ATP.
Explanation:
During exercise , our body needs more energy in the form of ATP. This ATP comes from break down of food materials in the mitochondria of the cell during cellular respiration. With the addition of oxygen, more ATP is produced during respiration and this ATP is used by the body. With ATP, carbon dioxide is produced as a waste material which can be removed by exhaled out during breathing.
