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.)

• 2

• 4

• 6

• 8

Hydra reproduce through __________, where the offspring grows from the body of the parent organism. (Some organisms reproduce through asexual reproduction.)

• budding

• DNA

• thymine

• mutations
