Answer:
cell memberane
Explanation:
cell memberane controls things going in and out of the cell
Protists = eukaryotic organisms tgat are mostly classfies as unicellular/ mostly seperate nuclear division phases of mitosis doesnt occur
for now we know that it is not d (bacteria) or a (too board)
c and b show describe a word called 'cell specialisation'
i think the answer is c since it is said to be mostly unicellular and we know that single cell doesnt have much specilaised cell
idk

It is A both chemical changes and flow of energy
Answer:
D. Molecules called pumps function to control active transport.
Explanation:
Active transport is one of the two types of transport (the other being passive transport). It is the type of transport in which substances move against their concentration gradient i.e. from a lower concentration to a higher concentration. Hence, due to this, energy input in form of ATP is required by the cell.
However, the process of active transport makes use of certain molecules called PUMPS to control it. The pumps moves ions/molecules against their concentration gradient. An example is the sodium-pottasium pump which moves sodium ions from a region of low conc. to a region of high conc.
