Two solutions are separated by a selectively permeable membrane, and water is observed moving from Solution A into Solution B until the levels stabilize. What can be concluded about the relative solute concentrations of A and B at the start? 

A bacterial cell carrying an antibiotic-resistance plasmid undergoes conjugation with a non-resistant cell via a sex pilus. What is the most likely outcome for the recipient cell? 

The process by which a cell releases materials to do the outside environment by fusing a vesicle with the cell membrane is called: 

A patient undergoing hemodialysis has their blood passed alongside a dialysis fluid across a selectively permeable membrane. If the dialysis fluid contains no urea and a lower concentration of potassium than the blood, what would you predict? 

A solution that has the same solute concentration as the inside of a cell is described as: 

Diffusion of substances across a membrane without the use of any cellular energy is known as: 

A cell needs to secrete a hormone made of protein to the outside environment. Which sequence of events, involving the endomembrane system, correctly describes this process? 

A scientist places dissolved starch and glucose in a dialysis bag and submerges it in plain water. After an hour, the surrounding water tests positive for glucose but negative for starch. What does this indicate about the dialysis membrane? 

During viral latency, what generally happens to viral gene expression? 

Cholesterol embedded within the cell membrane primarily functions to:
