Question 64 The cell formed through fertilization of an egg by a sperm is called a/an O zygote. O sperm cell. egg cell. O gamete. O ovum.

Question 4 Put the following events of neurulation in order, from first to last. Notochord signals ectoderm layer at top of v[Choose] embryo to form a neural plate Cells in the neural plate change shape, causing the neural plate to bend and form the neural groove. 4 3 The two sides of the neural plate come [ Choose ] together, forming a neural crest The neural tube pinches off by coming [Choose ) unglued from the neural crest The neural tube becomes the spinal cord and brain in the body and head, respecțively. [ Choose )

Question 19 The process of development Begins differently for humans than it does for chickens Includes the formation of a gut through a process called gastrulation All of the above Is totally different for birds than it is for cats Refers only to the changes in mammal growth that occur after birth

During the cleavage stage, this process takes the zygote from a single celled organism to multicellular morula.   Question 8 options:   Oogenesis   Spermatogenesis   Cytokinesis   Mitosis   Meiosis
