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.
Digestive system.
It would affect the digestive system because gallstones form in the binary tract, which are ducts leading from the liver to the small intestine.

Answer:
I hope it is helpful
Explanation:
Each lung is separated into lobes branching off the main bronchus; the right lung has three lobes, while the left has only two lobes. ... It creates a very smooth surface so that as the lungs expand and contract they can ride over the heart and surrounding elements.
To conduct a scientific investigation without bias, you would need to select a random sampling of people and set up preliminary guidelines. Questions need to be conducted and answers collected in the same manner for all people interviewed.
