Evolved from past organisms hope this helps!!!!
Answer:
Skin,muscles and metabolism play a significant role in maintaining his body temperature
Explanation:
Role of skin
In cold environment the blood vessels of the skin constrict to prevent the loss or liberation of heat from his(jim) body.
Role of muscles
The one of principle function of muscle is to store glycogen.The stored glycogen of jim"s muscle undergo glycogenolysis to generate heat inside his body.
Role of metabolism
In cold environment the rate of aerobic respiration and other catabolic reactions such as beta oxidation of fatty acid occur to generate energy in form of heat in his body.
Answer & explanation:
1. In the nitrification process, the oxidation of ammonia (NH₃) occurs, converting it to nitrite and, subsequently, to nitrate. This process is performed by chemosynthetic bacteria (also known as nitrifying bacteria), that is, they use the energy released in nitrification to synthesize their organic substances.
2. Denitrification occurs when bacteria in the soil called denitrifiers use nitrates and turn them into nitrogen gas. Denitrification ensures the return of nitrogen to the atmosphere.
3. The fixation of atmospheric nitrogen occurs mainly with the help of bacteria. These bacteria form nodules in the cortical region of the roots of these plants, where they act by capturing atmospheric nitrogen and transforming it into ammonia (NH₃), which will be used by plants.
