Answer: Option D. "Heme"

Explanation:

Deoxyhemoglobin can be defined as a form of which has no oxygen binded to the hemoglobin.

When deoxyhemoglobin is replaced with oxyhemoglobin then the oxygen binds to the heme component of the hemoglobin protein in red blood cells.

Each heme group has iron atom that has the ability to bind to oxygen (02) molecule.

Four oxygen molecules bind to a single hemoglobin protein.

Hence, the correct answer is option D "Heme".

A client is experiencing a sudden fluid shift as a result of diffusion. What variable most affects the rate of substance movemen
Vladimir79 [104]

Answer:

Concentration, Temperature, Mass of Particle, Solvent /medium, surface area and permeability properties of membrane.

Explanation:

The random movement of particles causes the phenomenon called diffusion. The concentration gradients of particles pushes molecules in a direction such that molecules move from a region of high concentration to a region of lower concentration.

Diffusion is a passive process (not requiring the input of energy).

The following variables are factors that affects diffusion;

Concentration - down concentration gradient favours diffusion.

Temperature - temperature increases diffusion , the kinetic energy associated with each particle also increases. 

Mass/size of Particle - Smaller particles on the other hand will diffuse faster because they can move faster.

Solvent /medium Properties - Viscosity and density of the medium greatly affect diffusion. Highly viscous and dense medium slows down diffusion.

Diffusion can occur through a membrane. The two factors that are particular to diffusion through a membrane are surface area and permeability.
