8 0

Answer:

Osmosis is movement of water molecules from an area of their higher concentration to area of their lower concentration through a semipermeable membrane.

Active transport is movement of molecules from an area of their lower concentration to area of their higher concentration using energy in form of ATP by pump proteins.

Why do iguanas have spikes
miskamm [114]

Iguanas have spines along their backs to help protect them from predators. They also have a bunch of extra skin below their necks called a dewlap. This dewlap helps them to regulate their temperature, which is helpful as they are cold-blooded and their bodies don't control their body temperature automatically.
