Students using 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 student groups different types of cells as shown.
Which table heading should the student use for the two groups?
1. Animal Cells 2. Plant Cells
1. Prokaryotic Cells 2. Eukaryotic Cells
1. Mobile Cells 2. Motile Cells
1. Fungal Cells 2. Bacterial Cells
The picture shows a student using a microscope to study a prepared slide of a single-celled organism.
A single-cell organism can be classified as a prokaryote based on the absence of -
a cell membrane
ribosomes
chromosomes
a nucleus
4. Some students used the information they gathered from lab investigations to prepare a table. They entered the table in their lab notebooks.
Which of these correctly identifies the two cells described in the table?
Cell 1 is eukaryotic, and Cell 2 is prokaryotic.
Cell 1 is prokaryotic, and Cell 2 is eukaryotic.
Both Cell 1 and Cell 2 are eukaryotic.
Both Cell 1 and Cell 2 are prokaryotic
Both euglena (eukaryote) and cyanobacteria (prokaryote) are photosynthetic unicellular organisms found in pond water. The feature that distinguishes euglena from cyanobacteria is the -
ability to maintain homeostasis
presence of ribosomes
ability to reproduce
presence of a nuclear membrane
A student produces a labeled drawing of a virus for a presentation. The student states that a capsid has a function similar to the nuclear membrane found in animal cells.
Which of these describes the similar functions of capsids and nuclear membranes?
Both transport proteins throughout the structures.
Both provide energy for activities in the structures.
Both protect genetic information for the structures.
Both code for the proteins needed for the reproduction of the structures.
In 1898 Friedrich Loeffler and Paul Frosch found evidence that the cause of the highly contagious hoof-and-mouth disease in livestock was a microscope infectious particle. It was discovered that this particle requires a host cell to reproduce.
Which pathogen is most likely responsible for causing hoof-and-mouth disease in livestock?
a bacterium, because it is contagious
a fungus, because it infects livestock
a protist, because it is microscopic
a virus, because it requires a host cell to reproduce
Which of these describes a difference between viruses and cells?
Cells contain protein, and viruses contain only carbohydrates.
Viruses have flagella, and cells have only cilia.
Cells reproduce independently and viruses require a host to reproduce.
Viruses have membranes
The human immunodeficiency virus (HIV) often infects and destroys CD4 T-cells. These CD4 T-cells are one of many kinds of white blood cells that are an important part of the immune system, which protect the body.
The most common danger related to the destruction of CD4 T cells is -
an increase in the risk of high blood pressure
an increase in the threat of diseases caused by microorganisms and viruses
a decrease in the flow of blood to vital organs
a decrease in the amount of oxygen being transported to issues.
The picture shows a 3D model of a virus called a bacteriophage. Bacteriophages can infect bacteria such as E.coli.
In what way are the bacteriophage and E.coli alike?
they contain antibodies
they reproduce by mitosis
they have identical genomes
they lack membrane-bound organelles
Which description best identifies this type of cellular transport?
Active transport, because energy is being used to move molecules against the concentration gradient
Facilitated diffusion, because energy is being used to move molecules with the concentration gradient
Osmosis, because energy is being used to move molecules with the concentration gradient
Endocytosis, because energy is not being used to move molecules against the concentration gradient.
In a study of physical endurance, researchers observed significant increases in the heart rates and breathing rates of participants immediately after they engaged in strenuous exercise.
Which statement best explains the increase in the heart rate and breathing rate during exercise?
the water concentration in the blood increases.
body cells require increased oxygen as energy is expended.
muscle cells increase in temperature and require fluid to reduce the temperature.
an increase in muscle activity causes increases in glucose levels in red blood cells.
The picture shows a contractile vacuole of a unicellular freshwater organism. The contractile vacuole regulates the flow of water into and out of the cell in an aquatic environment.
What condition caused the contractile vacuole to fill with water?
the concentration of water is greater outside the cell than inside the cell.
the temperature of water in the vacuole is higher than the temperature of its environment.
the concentration of water inside the cell is the same as the concentration outside the cell.
The temperature of water in the vacuole is lower than the temperature of its environment.
This diagram shows cellular activity across a cell membrane.
Which two process does this diagram most directly model?
energy conversion and synthesis of new molecules
synthesis of new molecules and homeostasis
transport of molecules and energy conversions
homeostasis and transport of molecules
Some students used vinegar to dissolve away the cells of these eggs and used these eggs as models of human red blood cells. The students observed the changes in the eggs when they were placed in different solutions.
Which statement best describes the role of the cell membrane in this model?
the cell membrane is an impermeable barrier that prevents water from entering the cell.
the cell membrane allows solutes to enter the cell, which causes the cell to shrink.
the cell membrane allows water to enter and leave the cell.
the cell membrane removes solutes from the environment.
The division of the cytoplasm is called
mitosis
interphase
cytokinesis
somatic
What is the purpose the the cell cycle checkpoints?
To repair damaged cells before they enter cell division.
To remove damaged cells from an organism.
What is the first checkpoint of the cell cycle?
Mitosis checkpoint
G1 checkpoint
G2 checkpoint
How many cell cycle checkpoints are there?
1
2
3
4
Which of the following is true for both bacteria and viruses?
both contain genetic material
can be killed using antibiotics
have a cell membrane
have a protein coat
Prokaryotic cells are different than eukaryotic cells in that
prokaryotic cells are living and eukaryotic cells are non living
prokaryotic cells don't have a true nucleus and organelles with a membrane
prokaryotic cells are much larger than eukaryotic cells
prokaryotic cells require oxygen and eukaryotic cells do not
One important way to control the spread of viruses is through
the use of vaccines
drinking a lot of tea
the use of other types of bacteria
the use of antibiotics
What type of cells contain a nucleus?
bacterial cells
virus cells
prokaryotic cells
eukaryotic cells
