1.
The reproductive system enables ...
a)
living beings to produce offspring. The reproductive system in males and females produces cells for reproduction.
b)
the sum of traits that have been transmitted from a person's biological parents.
c)
22 chromosomes plus an X or a Y chromosome.
d)
observable trait only if the other gene in the pair is the same.
2.
Males produce ...
a)
egg cells.
b)
sperm cells.
3.
Females produce ...
a)
egg cells.
b)
sperm cells.
4.
Each person begins as ...
a)
a fetus (FEE-tuhs).
b)
a single cell produced by fertilization.
5.
Fertilization (fuhr-tuh-luh-ZAY-shun) is the ...
a)
joining of a sperm cell and an egg cell to make a single cell called a fertilized egg. The fertilized egg divides and attaches itself to the uterus.
b)
the sum of traits that have been transmitted from a person's biological parents.
c)
a muscular organ in a woman's body that supports the development of the fertilized egg during pregnancy.
6.
The uterus (YOOtuh-rus) is ...
a)
a muscular organ in a woman's body that supports the development of the fertilized egg during pregnancy.
b)
the sum of traits that have been transmitted from a person's biological parents.
c)
strands of matter found in the nucleus of a cell. Most human cells contain 46 chromosomes, but reproductive cells contain only half as many.
7.
Heredity is ...
a)
the time between fertilization and birth, about nine months.
b)
an observable trait.
c)
the sum of traits that have been transmitted from a person's biological parents.
8.
You inherit traits through chromosomes (KROH»muh»sohmz), ...
a)
22 chromosomes plus an X chromosome.
b)
strands of matter found in the nucleus of a cell. Most human cells contain 46 chromosomes, but reproductive cells contain only half as many.
c)
22 chromosomes plus an X or a Y chromosome.
9.
An egg cell has ...
a)
22 chromosomes plus an X or a Y chromosome.
b)
22 chromosomes plus an X chromosome.
10.
A sperm cell has ...
a)
22 chromosomes plus an X or a Y chromosome.
b)
22 chromosomes plus an X chromosome.
11.
If a sperm cell with a Y chromosome fertilizes an egg cell, ...
a)
then a female will develop.
b)
a male will develop.
12.
If the sperm cell has an X chromosome, ...
a)
a male will develop.
b)
then a female will develop.
13.
A gene (JEEN) is ...
a)
a tiny piece of information found in a chromosome that controls heredity. DNA, an acid found in genes, carries this information. Each pair of genes contains information from both a mother and a father.
b)
cluster of cells and attaches itself to the walls of the uterus. This cluster of cells is known as the embryo (EM-bree-oh).
c)
the umbilical cord. The mother's blood passes through the cord to the fetus and carries away wastes.
d)
the time between fertilization and birth, about nine months.
14.
A dominant gene produces an ...
a)
observable trait.
b)
observable trait only if the other gene in the pair is the same.
15.
A recessive gene produces an ...
a)
observable trait.
b)
observable trait only if the other gene in the pair is the same.
16.
Pregnancy is ...
a)
a muscular organ in a woman's body that supports the development of the fertilized egg during pregnancy.
b)
the sum of traits that have been transmitted from a person's biological parents.
c)
the time between fertilization and birth, about nine months.
17.
After fertilization, the fertilized egg divides into a ...
a)
cluster of cells and attaches itself to the walls of the uterus. This cluster of cells is known as the embryo (EM-bree-oh).
b)
observable trait only if the other gene in the pair is the same.
c)
a fetus (FEE-tuhs).
18.
From the end of the eighth week until birth, the developing organism ...
a)
the time between fertilization and birth, about nine months.
b)
cluster of cells and attaches itself to the walls of the uterus. This cluster of cells is known as the embryo (EM-bree-oh).
c)
is called a fetus (FEE-tuhs).
19.
The mother-to-be provides the fetus in her uterus with food and oxygen through ...
a)
joining of a sperm cell and an egg cell to make a single cell called a fertilized egg. The fertilized egg divides and attaches itself to the uterus.
b)
a muscular organ in a woman's body that supports the development of the fertilized egg during pregnancy.
c)
the umbilical cord. The mother's blood passes through the cord to the fetus and carries away wastes.
20.
The health of a developing baby depends on the mother's health. Prenatal care is ...
a)
the health care given to an expectant mother and her unborn baby.
b)
strands of matter found in the nucleus of a cell. Most human cells contain 46 chromosomes, but reproductive cells contain only half as many.
c)
cluster of cells and attaches itself to the walls of the uterus. This cluster of cells is known as the embryo (EM-bree-oh).
21.
Teen pregnancy is risky for many reasons. ...
a)
The fertilized egg has divided many times before she knows that she is pregnant. Any drug use on her part can harm the developing baby.
