If the cell you were looking at had organelles such as a nucleus or mitochondria, then it is a eukaryotic cell.
However, if the DNA was simply coiled in the cell without a membrane around it to form a nucleus and there
were no other organelles such as chloroplasts, mitochondria, or lysosomes, then it is likely a prokaryotic cell.

Parts ii and v are valves that prevent the blood from flowing from the ventricles back into the atriums. This is
important so that all the blood in the ventricles is moved on to the lungs or the rest of the body in order to
provide oxygen to the rest of the body. If these valves do not function properly, the heart will not be able to
move as much blood as possible on to the lungs or the rest of the body, so the heart will have to work harder
to do its job.
