Respiration - The cellular process of releasing energy from food through a series of enzyme-controlled reactions is called respiration . Some of the energy released is used to produce ATP.
I choose the option (4) chemical bond.
Glucose is decomposed to 2 pyruvate, acetyl-CoA, and then entering the TCA cycle. All the energy such as ATP, NADH, and FADH2 is generated from braking the chemical bond.
Denitrification is the major process involved in converting nitrogen components present in the nitrogen gas and it is released into the atmosphere.
<u>EXPLANATION: </u>
With the help of the nitrogen cycle, the nitrogen that enters living things by nitrogen fixation is converted back into nitrogen and is released in the atmosphere by microbes.
The nitrogen-fixing bacteria converts the nitrogen contents into ammonia by the process called ammonification. Then it oxidizes ammonia to nitrite by the process called nitrification and these nitrates are absorbed by plants.
Then, the bacteria present in the soil convert nitrate back to nitrogen gas which is released back to the atmosphere.

Option-D
Explanation:
The skin toughness trait is determined by the genes which can control the components of skin like the amount of the collagen and the elastin. Also, the trait is influenced by the environmental factors which can act as a stimulus to either increase or decrease the components of the skin.
In the given case, when you walk barefooted develops the callus but when you walk with the shoes you do not develop calluses. Here the development of calluses is influenced by the environment which can lead to the increased production of collagen genetically which provides strength.
Thus, Option-D is the correct answer.
