A human is a complex organism that develops from a zygote. Briefly explain some of the the steps in this development process in the form of a
paragraph. In your answer, be sure to: 1) explain how a zygote formed, 2)
compare the genetic content of the zygote to the body cells of the
parents, 3) identify the structure in which embryonic/fetal development
usually occurs within, and 4) identify the structure that forms, which
provides nourishment and waste removal to/from the developing baby.

Match the following terms describing electrical events with the correct phases of the cardiac cycle. the ventricular muscle cells depolarize at the start of this phase. during this phase, na+ entry through the funny channels causes the pacemaker potential of sa nodal cells to gradually become less negative until it reaches threshold. the ventricular muscle cells repolarize right before this phase. the cytosolic concentration of calcium in the contractile cells of the ventricle is highest during this phase. a. isovolumetric relaxation b. ventricular ejection c. isovolumetric contraction d. ventricular filling
