PLS HELP ASAP If an animal cell wasn't in an isotonic solution, wouldn't active transport be able to balance the cell's volume?
ohaa [14]

Answer:

Animal cells tend to do best in an isotonic environment, plant cells tend to do best in

a hypotonic environment. This is demonstrated in the attached PDF.

Explanation:

A cell that does not have a rigid cell wall, such as a red blood cell, will swell and lyse (burst)  when placed in a hypotonic solution, a process called cytolysis. Cells with a cell wall will swell when placed in a hypotonic solution, but once the cell is turgid (firm), the tough cell wall prevents any more water from entering the cell. When placed in a hypertonic solution, a cell without a cell wall will lose water to the environment, shrivel, and probably die. In a hypertonic solution, a cell with a cell wall will lose water too. The plasma membrane pulls away from the cell wall as it shrivels, a process called plasmolysis.

I hope this helps. If not I am really sorry!

Which organism is a secondary consumer (3rd trophic level)? a. larvae b. copepods c. killifish d. snapper
anygoal [31]

ANSWER:  B, killifish

REASONING: A secondary consumer consumes animals that eat only plants.  Larvae and copepods do not fit these descriptions, because they do not eat animals.  Snapper do eat animals, so do not fit the description either.  Killifish eat small animals that do eat plants.
