a) All genetic material comes from one parent
b) Only some of the genetic material comes from one parent
c) The size of the parent determines the amount of genetic material

B) they have the same number of chromosomes
C) they have one-half the number of chromosomes
D) they have one-quarter as many chromosomes
C) they have one-half the number of chromosomes

What is the function of the placenta during the internal development of an offspring?
(Name 2)
- Oxygen and nourishment for the developing offspring diffuse across the placenta.
- The placenta allows the exchange of materials, including wastes, between the mother's blood and her developing fetus.
- The placenta protects the fetus from some infections by not allowing blood from the mother to flow to the fetus
400
Explain how harmful substances in the blood of a pregnant female can enter a fetus even though the blood vessels of the mother and fetus are not directly connected.
- Harmful substances can diffuse/pass through the walls of blood vessels and the placenta.
500
What are the disadvantages of asexual reproduction?
Without genetic variation, a population is more likely to die out because it cannot adapt to change.
500
Cancer of the ovary is not common, but when it occurs, the cancer can cause the ovary to malfunction. Identify one possible result of an ovary not performing its intended function in the body.
— No eggs would be produced
— A female might not produce estrogen/progesterone.
— A woman might have difficulty becoming pregnant.
— disrupts the female's menstrual cycle
500
Explain how process 2 increases genetic variation.
Process 2 combines genetic material from 2 individuals to create offspring that are not the same as the parents.
500
Identify one way in which the process of growth of a human embryo is similar to the process of reproduction in a single-celled organism.
– They both involve mitosis.
– Both processes produce cells containing identical genetic information.
– The cells are produced asexually.

When a pregnant woman ingests toxins such as alcohol and nicotine, the embryo is put at risk because these toxins can
A) diffuse from the mother's blood into the embryo's blood within the placenta
B) enter the embryo when it eats
C) transfer to the embryo since the mother's blood normally mixes with the embryo's blood in the placenta
D) enter the uterus through the mother's navel
A) diffuse from the mother's blood into the embryo's blood within the placenta
