- How does the blastodisc of the fertilized egg differ from an unfertilized one?arrow_forwardThis question is about mammals. a) What is the one defining characteristic that determines a mammal? b) Compare and contrast the three types of mammals with respect to fetal development and birth: the monotremes (such as the platypus), the marsupials (such as kangaroos), and the placentals (such as humans or dogs). That is, where does most of the early development occur, how is the young mammal introduced to the world, and how does the young obtain nourishment once introduced to the world?arrow_forwardWhat is the purpose of the placenta? Which part of the blastocyst eventually becomes the fetal placenta? In birds, developing chicks rely on the yolk sac to provide essential nutrients, but in humans, this is not the case.

- Zygote Embryo Muscle cells Intestinal cells Liver cells Blood cells Nerve cell Cardiac cells (1) Specialization occurs, resulting in the formation of a great variety of cell types. (2) Genes are inserted into the zygote to allow for the formation of different cell types. (3) The expression of genes responsible for the different cell types is controlled by the placenta. (4) The genetic information in the zygote is divided to produce a complete set for each cell typearrow_forwardWith regard to early cleavage in the sea urchin, is the entire zygote involved in early cleavage?
