Answer:
Cell Membrane---Semi-permeable
Explanation:
All cells have cell membranes, regardless of the type, and they are all semi-permeable, or selectively permeable, which means they can regulate what enters and leaves the cell.
Science is a dynamic subject and it changes all the time. In the science field, research is always on going and when new evidence are discovered about a particular topic, the new evidence are usually used to update the scientific information that is already on ground. All the areas of science listed about have enjoyed scientific updates in the recent.

Answer:
2.glucose move into chamber B faster than fructose
Explanation:
- Facilitated diffusion: refers to the transport of hydrophilic molecules that are not able to freely cross the membrane. Channel protein and many carrier proteins are in charge of this <u>passive transport</u>. If uncharged molecules need to be carried <u>this process depends on concentration gradients</u> and molecules are transported from a higher concentration side to a lower concentration side. If ions need to be transported this process depends on an electrochemical gradient. The glucose is an example of a hydrophilic protein that gets into the cell by facilitated diffusion. Facilitated diffusion is a passive transport process because the cell does not need any energy to make it happen.
The exposed scenario is an example of facilitated diffusion, a process that occurs in favor of the concentration gradient, and which rate depends on the concentration of molecules in each side of the membrane, in this case, glucose and fructose, among other factors that might also influence the diffusion rate. So, as the concentration of glucose is higher in chamber A (80%), and lower in chamber B (20%), in comparison with fructose, the first one will diffuse faster than fructose. The difference in concentration between both chambers is sharper in glucose, so its transport is faster than the fructose transport, which will also diffuse but at a lower rate.
The answer is a slim layer, Flagella, and a Fimbriae
Hope this helps!!
