Does the number of villi on a cell affect the diffusion rate?
si....
How the rate of diffusion principal is used while filling rubber tubes to increase the speed of vehicles?
Explain how rate of diffusion principle is used while filling air in the rubber tubes to increase the speed of the vehicles.
What is diffusion in the villi?
Same as anywhere else on the cell. The function of the villi is to increase the surface area, and thus the rate of diffusion.
Why do you think temperature affect rate of diffusion?
Temperature affects the rate of diffusion, by speeding up the movement of molecules. For example it kind of like when going from water to steam. The water molecule get heat added and speed up, like that of diffusion.
What is the advantage of the presence of on cell membranes?
the membrane has a greater surface area for an increased rate of diffusion
How does surface area to volume ratio of a cell affect rate of diffusion?
The surface area to volume ratio of a cell affects the rate of diffusion in that the higher the ratio, the faster the rate of diffusion. This is a directly proportional relationship.
What happens to the rate of diffusion when a cell gets to big?
It explodes

How does low temperature affect diffusion?
I'm pretty sure it would slow down the rate of diffusion, because higher tempuratures increase the rate of diffusion.
Can cell shape influence the rate of diffusion of nutrients and wastes?
hmmm????????? bcz of science?????

How can you use weights of the filled cell models to determine the rate and direction of diffusion?
If the cell model weighs more after the elapsed time (30 min in this case), it can be determined that water has diffused INTO the cell model. However if the cell model weighs less after the elapsed time (30 min in this case), it can be determined that water has diffused out of the cell model. The rate of diffusion compared to other cell models being investigated in the experiment can be determined by comparing the change in mass to other cell models. For example, if a cell model containing glucose changed + 15.7 % in mass over 30 minutes and a cell model containing sucrose changed + 27.3 % in mass over 30 minutes, it can be assumed that the diffusion rate in the sucrose model is faster than in the glucose model. You would have to have a way to measure solute concentrations and such in order to determine water potentials and what not. Hope this helps, just my insight from completing AP Biology Investigation 4. Current AP Biology student.
What is the advantage of the presence of on cell membranes?
the membrane has a greater surface area for an increased rate of diffusion
Why does diffusion take place faster when you heat the substance?
The acts as a catalyst to speed up the diffusion process, allowing the molecules to overcome it; the activation energy causes the reaction to proceed at the faster rate.
How can some substance diffuse through a cell membrane at faster rate than by diffusion alone?
In facilitated diffusion, there are temporary openings in the cell membrane that enable certain molecules to pass through quickly.
