Actually, it is both acquired and part of your DNA. There is a logical <span>explanation but you have to figure that out on your own.</span>
Amino acids make up proteins, and proteins are needed for proper growth in humans. They’re essential because, without them we wouldn’t have the nutrients we need to survive. I hope this helped!

Answer:
D. the need for a surface area of sufficient area to allow the cell's function
Explanation:
Many cellular functions such as the exchange of substances and respiratory gases, absorption of nutrients, cell-cell communication, etc. require the cells to have a sufficient surface area. A small cell has a larger surface area to volume ratio and therefore, maintains a higher rate of exchange of substances. As the cell increases in size, the surface area grows less than its volume. Therefore, the surface area required to perform the cellular functions puts an upper limit on the cell size.
Cells maintain the required surface area by dividing and/or by developing folding or projections on the surface. For instance, the cells in the wall of the small intestine require to maintain a higher surface area for nutrient absorption. Therefore, the cells of the wall of the small intestine develop microvilli to have a larger surface area which in turn supports a relatively higher rate of absorption.
