Answer:
<h2>
certain genes being expressed in some cells and not in others</h2>
Explanation:
The DNA is present in every cell of the multicellular organism but that does not mean that every cell will perform the same function.
The function of the cell is decided during the cell differentiation phase the function of the cell is determined by the expression of specific genes. Expression of these genes controls the functions of the cell.
In the given question the differences in the structure and function of the brain and kidney arise due to different expression of genes in different cells.
Thus, the selected option is the correct answer.
Mitochondrial it would be
The question is incomplete as it does not have the options which are:
A. Speciation
B. the founder effect
C. natural selection
D. gene flow
Answer:
Founder effect
Explanation:
The founder effect is the phenomenon observed when the members of the population establish a new population.
This effect is observed due to the immigration and emigration of the individuals of the population.
In the given question, the four lizards swept away with the ocean and reached a new island. There they reproduced and flourished and by the time they formed the new population with orange stripes. This is the case of the genetic drift especially the founder effect in which the new alleles for the orange tail expressed.
Thus, the founder effect is the correct answer.
I think it is increase the amount of substrate.
For use in (aerobic) respiration, polypeptides would first be hydrolysed to their amino acid monomers. These are each deaminated, i.e. have their amino groups removed, producing an organic acid, which can be fed into the Kreb's Cycle, and a waste product, ammonia (NH₃), which is moved to the liver and removed from the blood.
