Which describes one of the ways proteins behave in facilitated diffusion? a)they change membranes. b)they use atp. c)they change shape. d)they create channels..

Option D is correct.

D)They create channels.

Facilitated diffusion is the movement of molecules across the cell membrane of a cell through carrier proteins and protein channels. IN Facilitated diffusion no energy is required so it is called passive transport.

The molecules that can not directly diffuse across the membrane, they are transported through special channels and carrier proteins.

succession returns a disturbed

ecosystem to a more stable state. this is also classified into two (2) types:

primary succession and secondary succession. the primary succession arises when

a new land is transformed and a bare rock has been exposed providing an environment

that can be occupied for the first time. while, secondary succession occurs

when a previously occupied environment was disturbed that kills much of all its

community
