Structure A usually produces
(1) sperm and eggs
(2) testosterone and eggs
(3) estrogen, progesterone, and eggs
(4) estrogen, progesterone, and testosterone
One function of the male reproductive system in mammals is to
(1) produce insulin necessary for sexual reproduction
(2) transport eggs necessary for fertilization
(3) allow for delivery of gametes needed for reproduction
(4) provide protection for the developing zygote
If the placenta separated from the uterus, what harm might come to the fetus?
(1) There would be no oxygen or nutrients delivered to the fetal blood from its mother.
(2) The fetus would not get enough of its mother's blood.
(3) The fetus wouldn't receive milk from its mother any longer.
(4) The fetus wouldn't be given permission to continue growing by mitosis.
In an embryo, the formation of many types of tissues and organs occurs as a result of the process of
(1) fertilization
(2) genetic sorting
(3) differentiation
(4) gene recombination
Which factor has the greatest influence on the development of new, inheritable characteristics?
(1) combinations of genes resulting from mitosis
(2) mutations of genes in reproductive cells
(3) sorting of genes during asexual reproduction
(4) recombining of genes during differentiation
Which process allows a mammal to continue to grow in size?
(1) mitosis of sex cells
(2) mitosis of body cells
(3) meiosis of sex cells
(4) meiosis of body cells
Which sequence best represents sexual reproduction?
(1) mitosis → gametes → zygote → fertilization
(2) gametes → meiosis → mitosis → fertilization
(3) fertilization → gametes → meiosis → zygote
(4) meiosis → gametes → fertilization → zygote
Some variation must be present in a population in order for natural selection to take place. These variations arise from mutations in the DNA and
(1) sorting of chromosomes during sexual reproduction
(2) combining of chromosomes during organ development
(3) changing of chromosomes during cloning
(4) removal of chromosomes during selective breeding
A man is exposed to large amounts of ultraviolet radiation while sunbathing at the beach. This exposure causes a genetic change in the DNA of a skin cell. In the future, this change can be passed on to
(1) his male and female children
(2) his male children, only
(3) all cells in his body
(4) his skin cells, only

Row 4
What will happen once the liquid plant extracts are added to the chromatography paper?
(1) the extracts will disappear
(2) the extracts will move upward, separating pigments as the shallow water rises.
(3) the extracts will move down into the shallow water.
(4) the extracts will fizz on the chromatography paper.
Which chemicals are used to cut DNA into fragments for a gel electrophoresis procedure?
(1) restriction enzymes
(2) molecular bases
