Fick's law states that:

A) the amount of gas diffusing across a membrane depends on differences in partial pressure.
B) the total pressure of a mixture of gases is the sum of the pressures of the individual gases.
C) the dissociation of oxygen from hemoglobin depends on the pH of the environment.
D) as oxygen concentration increases, there is an increase in the amount of hemoglobin produced.
E) the size of an animal varies inversely to the amount of diffusion across its respiratory membranes.

Fick's Law

A principle in physics and chemistry describing the rate of diffusion of a substance across a space, influenced by the concentration gradient, surface area, and other factors.

Partial Pressure

The pressure exerted by a single type of gas in a mixture of gases, often used in calculations involving gas laws and respiration.

Hemoglobin

Located in red blood cells, this compound is tasked with the transfer of oxygen from the lungs to the body's tissues and the retrieval of carbon dioxide, taking it back to the lungs.
