Which mechanism requires energy?

a) diffusion of oxygen into red blood cell

b) diffusion of ions through a potassium channel

c) osmosis

d) exocytosis

d is the correct answer because Exocytosis is a type of vesicle transport which cells use to move substances out of their interior. It is an active process because it requires the energy of ATP to occur. ATP occurs when the last phosphate breaks tahts how energy flows through

your answer is true

i am 100% sure

explanation:

there are mainly three domains in biological classification namely; archaea, bacteria, and eukarya.

archaea includes all the prokaryotic cells which are characterized by their lipid membranes. they have branched hydrocarbon which is attached to glycerol through an ether linkage.

bacteria includes all the prokaryotic cells, the cell membrane of which are made up of the unbranched fatty acid chain. in addition, they are attached to glycerol through an ester bond.

eukarya includes all the eukaryotic cells, that is, the cells contain a nucleus and other membrane-bound cell organelles.

they can be autotrophic as well as heterotrophic, unicellular as well as multicellular

they include kingdoms like protista, plantae, animalia, fungi et cetera.
