Answer:
The correct answer is <em>c. animal wastes and fertilizers. </em>
Explanation:
Two major sources of nitrate pollution are farming and breeding activities. There are also certain industrial activities involved in nitrate pollution, but in general, these industries are related to agriculture.
The indiscriminate use of fertilizers for several years in intensive productions produce high nitrate concentration in soil and consequently elevate the risk of nitrate lixiviation.
Breeding animals produce nitrate pollution by their wastes, which accumulate and are not treated. These wastes include flesh, hair, feathers, skin, fat, liquids, excrements, among others. These wastes are an important source of nitrate.
In many cases, animal wastes are used by farmers as organic matter to improve their production. But excessive and incorrect use of it might produce severe damage in water sources.
The human body reserves creatinine phosphate as the energy source at the start of 100 yard dash (race).
The creatinine phosphate is converted into ATP, which is the energy package of our body. ATP is body's usable form of energy. Energy is stored in various forms in our body such as fats, carbohydrates and proteins. At a microscopic level, it is stored in molecules like creatinine phosphate. Carbohydrate and fats are the primary source of our body followed by proteins.
Our body uses three different forms of metabolism to convert these molecules in ATPs. These three processes are Phosphagen System, Aerobic Respiration and Glycolic/Anaerobic respiration.
