The correct answer for the question that is being presented above is this one: "d. amount of plankton." The key abiotic factor in marin ecosystems includes the water temperature, the amount of sunlight and the water depth. The amount of plankton is not really an issue.
This one’s a little tricky. I think your 2 best options are B and D
Not sure if you want to represent the particles moving but not making contact, which would be B or the particles moving and keeping contact which would be D.
Hope this helps a little

Answer: Amino acids; peptide
Explanation:
20 different AMINO ACIDS link together to form chains. A protein is composed of one or more of these PEPTIDE chains which are twisted and folded into a particular shape.
There exists 20 amino acids capable of forming protein in the Human body. At least two amino acids are joined together by a peptide bond to form polypeptide chains that are then held together by hydrogen bonds in twisted alpha helical structures to form proteins.
The asters function in cell division is to separate the sister chromatid away from each other to process the Telophase
Thus, if the cell grows beyond a certain limit, not enough material will be able
to cross the membrane fast enough to accommodate the increased cellular
volume. When this happens, the cell must divide into smaller cells with
favorable surface area/volume ratios, or cease to function.
