48
Q

When does diffusion stop?

A

At an equilibrium

49
Q

What is the molecular structure of chitin?

A

Carbohydrates similar to cellulose

50
Q

Explain diffusion.

A

It is the net movement of molecules from a higher area of concentration of that substance to a lower area of concentration, this is due to kinetic molecular energy in the molecules

51
Q

In living organisms the membranes that permit only certain materials to pass through them are called what?

A

Semi permeable

A

Changes amount of activation energy

56
Q

What substance is often called a universal solvent?

A

Water

Q

What happens when diffusion pressure is high?

A

Diffusion occurs rapidly because equilibrium is not there
