The cell that is formed when fertilization occurs is called a __________. (Think about what happens when an egg and a sperm join together.)
zygote
mutation
chromosome
cytoplasm
What is the process shown in this figure? (The chromosomes are identical to only one cell donor.)
budding
cloning
regeneration
vegetative reproduction
During which phase of meiosis do homologous pairs of chromosomes separate? (Sister chromatids separate in meiosis II.)
anaphase I
prophase I
anaphase II
telophase II
Which conclusion can be drawn from this picture? (Each sex cell has one half the number of chromosomes of the parent.)
An egg cell and a sperm cell unite to form a zygote.
Kittens will always look like the father.
Sperm cells come from the mother.
Mitosis produces egg and sperm cells. Mitosis produces egg and sperm cells.
A sea star has one of its arms break off. That arm grows into its own separate organism through __________. (Some organisms can re-grow a body part if it becomes damaged.)
sexual reproduction
regeneration
spindle fibers
chromosomes
During which phase of meiosis do chromosomes condense and thicken? (Chromosomes need to condense and thicken before they are spit into different cells.)
metaphase I
prophase I
anaphase II
metaphase II
In asexual reproduction, offspring are produced ________. (This type of reproduction produces offspring with genetic material that is identical to its parent.)
from one parent
from two parents
from 46 chromosomes
from 8 chromosomes
The process that produces haploid sex cells is __________. (Most animals would not live if they received twice as many chromosomes as needed.)
mitosis
fission
meiosis
interphase
If fission takes place every 20 minutes in some bacteria, then starting with one bacterial cell, how many bacterial cells would be produced in three cell divisions or one hour? (Each cell divides and produces two daughter cells.)

Hydra reproduce through __________, where the offspring grows from the body of the parent organism. (Some organisms reproduce through asexual reproduction.)
budding
DNA
thymine
mutations
Human reproduction involves which of the following? (These cells have only a haploid number of chromosomes.)
body cells
sex cells
skin cells
mitochondria
Which of these organisms can perform the same type of reproduction as the one shown in the figure? (Sea urchins and sponges can also reproduce in this manner.)
human
sea stars
strawberry plants
sheep
Which of these is part of asexual reproduction? (Think about the process where an offspring is produced from one parent.)
sperm
egg
zygote
bud
What is the mathematical relationship between the number of chromosomes and the number of homologous pairs? (The numbers on the chart show the mathematical relationship.)
There is no mathematical relationship between the number of chromosomes and the number of homologous pairs.
The number of chromosomes is related directly to the age of the organism, so the number of homologous pairs changes.
There is only one chromosome in each homologous pair.
There are one half as many homologous pairs as there are chromosomes.
If a diploid tomato cell has 24 chromosomes, how many chromosomes will the tomato's sex cells have? (Sex cells are haploid.)
