A vaccum should be used for the control group chamber.

Explanation:

In an experiment, a control is an experiment or observation designed to minimize the effects of variables other than the independent variable. The introduction of a control increases the reliability of the results; often through a comparison between the control measurements and the other measurements.

A vaccum according to this experiment is a chamber that will have no pressure within it. This will give a benchmark of the effect of pressure in this experiment.

How would a small, uncharged lipid move across the cell membrane?
ElenaW [278]

Answer:

Through simple diffusion, down the concentration gradient.

Explanation:

The phospholipids of the membrane are amphipathic with hydrophillic heads and hydrophobic tails. Other polar molecules cannot go through this hydrophobic interior. Since small uncharged lipids are non polar and hydrohobic, they are able to go through the membrane without the help of transport proteins. Therefore, the last two options can be ruled out because facilitated diffusion includes the use of a protein. Diffusion involves molecules moving down the concentration gradient so the second option can be ruled out.
