Increased pressure in the ventricles would close what valve(s)? Increased pressure in the ventricles would close what valve(s)? AV valves only semilunar valves only both semilunar and AV valves

Atrioventricular valves (AV) only

Explanation:

During the early phase of ventricular systole, when the pressure in the ventricles is increased, the atrioventricular valves (mitral/tricuspid) closes. When the pressure in the ventricles exceeds the pressure in the aorta/pulmonary trunk the aortic/pulmonary valves open and blood is pumped from the heart into the great arteries.

interphase   is the cell cycle stage in which the cell acquires nutrients, creates and uses proteins and other molecules and starts the process of cell division by replicating the dna. it is the longest stage in the eukaryote cell cycle.

the following   can go wrong during interphase:   a base pair could be mismatched during the duplication process causing a mutation.   correct answer: c
