Students use a microscope to look for structures present in four different cells. The students placed an X for each structure that was viewed for each cell on the table shown. Which cell that was viewed is most likely a prokaryote?
Cell W
Cell X
Cell Y
Cell Z
A prokaryotic cell and a eukaryotic cell are shown. Which characteristic best distinguishes these cells as either prokaryotic or eukaryotic?
The organization of the genetic material
The location of the cytoplasm
The role of the cell membrane
The function of the flagella
The activities in the cell cycle occur during specific phases. In which phase of the cell cycle is DNA replicated?
Mitosis
G1 phase
G2 phase
S phase
This model of the cell cycle includes two arrows that each represent a process in the cycle.
Arrow 1 represents prophase, and Arrow 2 represents interphase.
Arrow 1 represents mitosis, and Arrow 2 represents meiosis.
Arrow 1 represents interphase, and Arrow 2 represents mitosis.
Arrow 1 represents meiosis, and Arrow 2 represents prophase.
Which biomolecule makes up the cell membrane and hormones?
lipids
protein
nucleic acid
carbohydrate
Beeswax is a waxy substance that is produced by bees and then harvested by humans for a variety of uses. Ancient Romans used beeswax as a waterproofing agent because it is not water-permeable. Beeswax is which of the following types of organic molecule?
carbohydrate
lipid
nucleic acid
protein
Many land plants store energy in starch. When energy is needed, the starch molecules can be broken down quickly. This chemical reaction produces which of the following?
amino acids
lipids
monosaccharides
RNA chains
Which of the following activities occur in the S phase?
Prophase
Anaphase
Telophase
Interphase
Which of the following activities occur in the G1 phase?
F
G
H

Oncogenes are mutated forms of genes. Oncogenes can transform a cell into a tumor cell. Some tumor cells are benign, while others are malignant. How does the presence of an oncogene lead to the formation of a tumor?
ATP Production is inhibited.
Cell division is unregulated.
Somatic cell growth is inhibited.
Antibody Activity is unregulated.
A laboratory assistant was told to watch the mitosis of a eukaryotic cell under the microscope and inform the lead scientist when the cell entered prophase. What should the assistant expect to look for to indicate that the cell is in prophase?
The chromosomes gather at opposite ends of the cell and uncoil, and then two new nuclear envelopes form around this genetic material.
The sister chromatids separate into individual chromosomes and are moved apart.
The chromosomes line up across the center of the cell, and each chromosome is connected to a spindle fiber.
The chromatin condenses into chromosomes, the nuclear envelope breaks down, and a spindle begins to form.

1
2
3
4

bees and grasshoppers
snakes and hawks
grasshoppers and rabbits
