Practice Quiz Active and Passive Transport

What is the difference between active and passive transport?

• Active does not use energy and passive uses energy

• Active uses energy and passive does not use energy

What is homeostasis?

• How the body/cell maintains balance

• how the body/cell stays unbalanced

What does semi-permeable mean?

• Only some things can move through membrane

• Nothing can move through membrane

What is equilibrium?

• When concentrations cannot be balanced between two substances

• When concentrations are balanced between two substances/sides

Diffusion is the movement of molecules from an area of higher concentration to an area of lower concentration.

• True

• False
