The right answer is D. renal regulation.
Among the many factors that modulate tension (vessels, heart strength, blood volume ...), the kidney plays a vital role because it makes an enzyme called renin that helps increase blood pressure and it regulates the outflow of sodium and water, which contribute to the elevation or diminution of blood pressure in the arteries.
 
        
             
        
        
        
The people who represented the Denisovan species are more likely to be related to <span>Neandertals, rather than human beings (Homo sapiens). The former differs from the latter at 202 positions of the mitochondrial DNA. Their fossil records claim that humans, Denisovans, and Neandertals have the same ancestry. </span>
        
             
        
        
        
Nitrogen is a fundamental element required during the growth and development of any organism.
- Nitrogen is a fundamental chemical element required to synthesize different biomolecules such as nucleic acids (either DNA or RNA) and proteins.
- Amino acids are the bounding blocks of proteins, whereas nucleotides are the building blocks of nucleic acids, and both contain nitrogen.
- All organisms in their growth phase requires nitrogen in order to synthesize these biomolecules (i.e., nucleic acids and proteins).
In conclusion, Nitrogen is a fundamental element required during the growth and development of any organism.
