Answer:
Water, carbon dioxide, and oxygen are among the few simple molecules that can cross the cell membrane by diffusion
Explanation:
Transport proteins generally perform two types of transport: “facilitated diffusion,” where a transport protein simply creates an opening for a substance to diffuse down its concentration gradient; and “active transport,” where the cell expends energy in order to move a substance against its concentration gradient
Riparian zones are attractive to livestock because they contain lush vegetation that livestock like to eat.
Riparian zones are the transitional areas between land and a water body such as rivers, streams, or lakes.
