Answer:
Nine
Explanation:
These are called carrier proteins, and they have what it is called: solute-binding sites, that when saturated, they are considered "full".
Each different amino acid needs a separate carrier protein to move it across the plasma membrane, so that's 3, then the four different sugars need separate carriers as well, we add 4 more then, we have 7 so far, finally the 2 different ions use 2 more, plus the other 7, totals 9.
The correct answer is indicator species.
Answer:
The vegetative cells found in all the kinds of organisms that form the body of an organism are known as somatic cells. They are found in both multicellular and unicellular species. In humans, a somatic cell comprises 46 chromosomes with 23 pairs coming from each parent. However, these cells are non-reproductive.
On the other hand, the gametes refer to the cells that are considered as the reproductive cells of the organism. They are also known as sex cells as they develop into sperm and egg cells. These cells are haploid in nature, and they are formed at the time of meiosis.
