PLEASE HELP Cells of all organisms have various mechanisms to control their metabolism. Some animals go into hibernation in response to changing environmental conditions. Their metabolism slows down to decrease their need for food. Which statement best explains this ability to change metabolism?

a. Animals that hibernate have genes that code for hibernation.
b. Phenotypes control the hibernation genotype, determining metabolism regulation.
c. Genes that regulate metabolism are multi-factorial and adjust to environmental changes.
d. Genes that regulate metabolism can mutate to adjust to temperature and lack of food.

18. determine whether each stateme blank space given. ach statement is true (t) or false (f). place your answer in the 8. when a cell is put into an isotonic solution, individual wat put into an isotonic solution, individual water molecules cannot move back and forth across the cell membrane. d. when a cell is put into a hypertonic solution, there is a net movement of water molecules across the cell membrane into the cell. c. when a cell is put into a hypotonic solution, there is a net movement of water molecules across the cell membrane out of the cell. d. the movement of any solvent across a semi-permeable membrane is called osmosis. e. carrier proteins have the ability to change shape and physically move molecules across the cell membrane. f. in facilitated diffusion, the concentration of the molecules to be moved across the cell membrane is higher inside the cell.
