The answer is B.
This is because it says that the population tends to level off meaning that it stays around the same population size since it is the maximum amount of individuals that can survive.
Answer:Gravity is super important to our everyday lives. It is the Sun's gravity that keeps the Earth in the suns orbit. All of the Life on Earth needs the Sun's light and warmth to survive. Gravity helps the Earth stay just the right distance away from the Sun, so it's not too hot or too chilly.

Explanation:
Alpha helix is a secondary structure of proteins, it is made of 3.6 aminoacids residues per turn, this structure is possible thanks to local hydrogen bonding between C=O and N-h groups. The result is a cylindrical structure with a hydrogen-bonded backbone and the outside studded with side chains.
Glycin has an -H in its side chain, this makes it a too flexible molecule, therefore it's unusual to find them in alpha-helical structures because their presence could cause the helix to deform. Large R-groups can also affect this stability, phenylalanine has a bulky aromatic side group, this discards it as a stabilizer. Serine has a hydrogen bond donor or acceptor as a side chain, due to the proximity to the main chain it competes with the main chain to form NH and CO bonds. Alanine is the most common amino acid in alpha-helix structures because it has a short and no charged R group (unlike arginine that even when it's short it has a charged R-group), this makes it flexible enough to keep the structure stabilized.
