zygote
gonad
gamete
blastula
The process illustrated by the diagram is known as
regeneration
gametogenesis
sporulation
cleavage
Which statement best explains this development?
Specialization occurs, resulting in the formation of a great variety of cell types.
Genes are inserted into the zygote to allow for the formation of different cell types.
The expression of genes responsible for the different cell types is controlled by the placenta.
The genetic information in the zygote is divided to produce a complete set for each cell type.
In an organism, a muscle cell has the same DNA as a nerve cell, yet the cells perform different functions. This is possible because
different mutations occur in each cell type, changing the genetic instructions
temperature variations within the body alter DNA
proteins in each cell type change the structure of DNA
different parts of the genetic instructions are used in each type of cell

For a human zygote to become an embryo, it must undergo
fertilization
recombination
meiotic divisions
mitotic divisions
What would most likely happen if structure X were damaged in the early stages of pregnancy?
The genes from the mother would not be turned on in the fetus.
The nutrients necessary for development would not be able to reach the fetus.
The fertilized egg would not be able to travel from the ovary to the uterus.
Development would take longer since the fetus would have to synthesize nutrients.
In humans, the placenta is essential to the embryo for
nutrition, excretion, and reproduction
respiration, nutrition, and excretion
movement, reproduction, and nutrition
coordination, movement, and growth
The major function of the placenta is to
cushion the fetus so it won't be hurt when the mother moves
exchange food, oxygen, and waste between mother and fetus
store food for the fetus
support the egg for the process of fertilization
