One function of the male reproductive system in
mammals is to
produce insulin necessary for sexual
reproduction
transport eggs necessary for fertilization
allow for delivery of gametes needed for
reproduction
provide protection for the developing zygote

in yeast.Yeast produce offspring that usually have
genes that are different from those of the
parent
genes that are identical to those of the parent
half of the genetic information of the parent
organelles that are not found in the parent
The diagram below represents division of a cell that produces two daughter cells. Which statement most likely describes the daughter cells produced?
The daughter cells will pass on only half of the genetic information they received from the
original cell.
The daughter cells will each produce offspring that will have the same genetic information as
the original cell.
The daughter cells will each undergo the same mutations as the original cell after reproduction has occurred.
The daughter cells will not pass on any of the genes that they received from the original cell.

ovary – provides milk for newborns
testis – development of sperm
placenta – storage of released eggs
uterus – produces estrogen
Which structure is correctly paired with its function?

genetically identical to parents
one parent, union of gametes, offspring similar
to but not genetically identical to the parent

The Critical Role of the Placenta
The proper functioning of the placenta is critical to the growth and development of a healthy fetus. For example, the placenta appears to act as a nutrient sensor. It regulates the amounts and types of nutrients that are transported from the mother to the fetus. Improper functioning of the placenta can alter the structure and function of specific cells and organ systems in the developing fetus, putting it at risk for health problems as an adult. For example, in some pregnancies, the placenta develops a resistance to blood flow. This resistance appears to force the heart of the fetus to work harder. This could result in an increased chance of the individual developing heart disease as an adult. A group of hormones known as glucocorticoids affects the development of all the tissues and organ systems. One of the things this group of hormones does is to alter cell function by changing the structure of cell membrane receptors. State the role of the uterus in the development of the fetus and the placenta.
A large number of sperm cells are produced by males every day. This large number of sperm cells increases the chance that
enough sperm cells will be present to transport the egg from where it is produced to where it develops into a fetus
some of the sperm cells will survive to reach the egg
several sperm cells will unite with an egg so the fertilized egg will develop properly
at least one sperm cell will be reached when the eggs swim toward the sperm cells in the ovary
Which statement best describes the relationship between the blood of a human fetus and the blood of the mother?
Their blood systems are separate only at certain times in development and connected at other times.
The blood flows directly from the mother into the fetus.
Their blood systems are separate and no materials are exchanged.
Their blood systems are separate, but certain materials pass from one to the other
Which hormone does not directly regulate human reproductive cycles?
progesterone
estrogen
testosterone
insulin
Which sequence represents the order of some events in human development?
zygote → embryo → fetus
embryo → zygote → fetus
fetus → embryo → zygote
zygote → fetus → embryo
The graph below shows the relative concentrations of certain hormones in the blood during the human female reproductive cycle. Which hormone has the lowest concentration on which day?
hormone A on day 4
hormone B on day 2
hormone C on day 12
hormone D on day 20
Which process usually results in offspring that exhibit new genetic variations?
Which statement concerning production of offspring is correct?
Production of offspring is necessary for a species to survive, but it is not necessary for an individual to survive.
An organism can reproduce without\ performing any of the other life processes.
Production of offspring is necessary for an individual organism to survive, while the other life processes are important for a species to survive
Reproduction is a process that requires gametes in all species.
The diagram to the right represents a system in the human body. The primary function of structure X is to
produce energy needed for sperm to move
provide food for the sperm to carry to the egg
produce and store urine
form gametes that may be involved in fertilization
German measles is a disease that can harm an embryo if the mother is infected in the early stages of pregnancy because the virus that causes German measles is able to
infect the eggs
pass across the placenta
be transported to the embryo in red blood cells
be absorbed by the embryo from the mother’s milk
