Question 1

Question

You're looking at a sample from your patient under the microscope. Does your patient have a virus? - ProProfs

You're looking at a sample from your patient under the microscope. Does your patient have a virus?

a
Yes, my patient has a virus, as this a typical viral structure.
b
No, my patient does not have a virus, this is a bacterial cell.
c
Yes, my patient has a virus, since this is not a cell.
d
No, my patient does not have a virus, this is a fungal cell.
Question 2
Viruses are exceptions to the cell theory, but they have some characteristics of living things. What is one of these characteristics?

a
They contain genetic material.
b
They reproduce by mitosis.
c
They contain chlorophyll.
d
They are made up of many specialized cells.
Question 3
What function do ribosomes have within a cell?

a
Ribosomes synthesize proteins.
b
Ribosomes contain genetic material.
c
Ribosomes produce ATP.
d
Ribosomes control what enters and exits the cell.
Question 4
Which three organelles work together to prevent a plant cell from bursting when it has absorbed too much water?

a
vacuole, cell wall, and cell membrane
b
ribosome, cell membrane, and Golgi apparatus
c
cytoplasm, cell wall, and endoplasmic reticulum
d
lysosome, cell membrane, and chloroplast
Question 5
How is a mitochondrion's structure related to its function?

a
The complex folding pattern of the mitochondrion's membrane provides many sites where reactions can occur.
b
Mitochondria have no internal membranes.
c
The mitochondrion's internal membrane is not folded, which allows more sites for reactions.
d
The complex folding pattern of the mitochondrion's membrane does not provide many sites where reactions can occur.
Question 6
Single-celled organisms utilize organelles to maintain homeostasis, while large multicellular organisms, such as humans, use organs to maintain homeostasis. How are organelles and organs similar?

a
Organelles are similar in function to organs.
b
Organelles are specialized for cellular respiration while organs are specialized for breathing.
c
Organs are specialized for metabolism while organelles are specialized for homeostasis.
d
Organelles are similar in structure to organs.
Question 7
Researchers conducted a study concerning cellular transport in animal cells affected by mitochondrial disease. The disease affects an organism's ability to produce adenosine triphosphate (ATP). During their study, which method of cellular transport still functioned in the affected animal cells?

a
Simple diffusion
b
Phagocytosis
c
Active transport
d
Pinocytosis
Question 8
Crystals of dye, when placed in a beaker of water, eventually spread evenly throughout the water. This is an example of

a
phagocytosis.
b
diffusion.
c
osmosis.
d
active transport.
Question 9
Why does active transport require energy to move molecules of a substance across a cell membrane?

a
The substance moves from low to high concentration, against the concentration gradient.
b
The cell membrane is very thick.
c
The substance moves from high to low concentration, with the concentration gradient.
d
Lack of the substance makes the cell weak.
Question 10
A student is investigating the process of osmosis. She fills a medicine dropper with red blood cells. Next, she creates a saline solution that is isotonic to the red blood cells. What will most likely happen to the red blood cells after they are placed in the solution?

a
Water will exit the cells and cause them to shrink in size.
b
Water will neither enter or exit the cells and their sizes will remain the same.
c
Water will enter and exit the cells at a steady rate and their sizes will remain the same.
d
Water will enter the cells and cause them to grow in size.
