The nuclear lamina represses gene expression in all of the following ways EXCEPT by:

What substance is LEAST likely to diffuse through a lipid bilayer on its own (without the help of a membrane transport protein)?

Which statement is FALSE about the ubiquitin pathway?:

In flourescence microscopy, the reason that excitation light and emission light are different colors is because: 

Phospholipids that have small polar headgroups and 2 long fatty acid tails are more likely to form:

The internal temperature of hibernating mammals, such as bears, drops when they hibernate. How do they maintain the fluidity of their cell membranes to compensate for this drop?

Trans unsaturated fatty acid tails pack:

What is a TRUE statement about passive transport

In plant cells, H+ pumps maintain a low concentration of H+ inside the cell. As long as a low H+ concentration is maintained inside the cell, H+ -driven symporters on plant cell membranes can use the electrochemical gradient of H+ to:

The “hydrophobic effect” is the driving force of the spontaneous assembly of the lipid bilayer of cell membranes in water. What does that mean?
