Answer:
The correct answer is option b. "Malnutrition has no significant effect on the genomic base pair content of a person's muscles".
Explanation:
Chargaff's Rules state that the content of nucleotides in the cells have a 1:1 ratio of pyrimidine and purine bases and the composition of DNA varies from one species to another but not within the same specie. Therefore according to Chargaff's Rules malnutrition has no significant effect on the genomic base pair content of a person's muscles, since no variation of the genomic base pair content should occur within the same person or specie.

For functioning of heart, circulatory and execratory systems are required.
Explanation:
It requires at least two body systems to perform the function because the functions does not be completed solely, it requires coordination among systems which help them to fulfill their task.

Nitrogen get into the air by lightning strike or fires by certain types of bacteria.
The structure shown by the red arrow is cell membrane.
In biology, cell membrane refers to the thin layer, which develops the external boundary of a living cell. It has three primary functions, which are as follows:
1. It comprises channels and receptors, which permits particular molecules like nutrients, ions, metabolic components, and wastes to pass between the cell and the outside environment.
2. It prevents toxic components from entering the cell.
3. They distinguish essential but incompatible metabolic procedures conducted within the cell.
