Cells in a cat’s pancreas produce insulin, but the cells in its heart do not. Which statement best explains this?
Heart cells have too many ribosomes.
Heart cells have too few mitochondria.
The genes for insulin production are activated in heart cells.
The genes for insulin production are not activated in heart cells.
What cells can differentiate into specialized cells when grown in the right laboratory culture conditions?
only adult stem cells
only embryonic stem cells
only bone marrow stem cells
both embryonic and adult stem cells
The diagram below shows the process of differentiation by which stem cells become specialized body cells such as nerve cells, muscle cells, and blood cells.
How are these specialized cells similar to one another and to the stem cells?
All the cells have the same DNA.
All the cells have the same function.
All the cells produce the same proteins.
All the cells produce nutrients the body needs.
Which of these cells in the human body is specialized to transport oxygen throughout the body?
Genes are located on chromosomes which are composed of
DNA
RNA
ATP
ADP
In a laboratory setting, embryonic stem cells can differentiate into which types of cells?
any type of eukaryotic cell
any type of prokaryotic cell
any type of cell from the same organism
any cell from a different organism
Which type of cell will result from a DNA code for cells specialized in fighting off infections?
fat cell
white blood cell
sperm cell
red blood cell
As an embryo develops, what process is responsible for cells becoming eye or liver cells?
repression
expression
transcription
differentiation
Below is a flow chart of the hierarchy of cell organization in the human body.
What term should be placed between the terms cells and organs?
body
tissues
structure
body systems
Which difference can be observed when comparing a muscle cell to a sperm cell?
Muscle cells have a nucleus, while sperm cells only have DNA.
Muscle cells move in one spot by contraction, while sperm move by traveling a distance with flagella.
Muscle cells have a flagella to move with, while sperm cells have cilia to move with.
Muscle cells do not communicate with each other or other cells, while sperm cells communicate with each other and other cells.
Which cell types can differentiate into a variety of cells?
stem cell
nerve cell
blood cell
sperm cells
Which matches the cellular structure with its function in the human body?
red blood cells—carry signals neurons—carry oxygen T lymphocytes—destroy bacteria
red blood cells—carry oxygen neurons—destroy bacteria T lymphocytes—carry signals
red blood cells—carry signals neurons—destroy bacteria T lymphocytes—carry oxygen
red blood cells—carry oxygen neurons—carry signals T lymphocytes—destroy bacteria
A child touches a hot stove. Which types of cells communicate with each other to make the child remove her hand?
skin cells
bone cells
nerve cells
red blood cells
Sperm cells, which are structured by DNA, have more mitochondria than egg cells. Which assumption could be drawn from this information?
Sperm cells require more energy than egg cells.
Sperm cells are unable to travel as far as egg cells.
Sperm cells produce the energy that is used by egg cells.
Sperm cells use more energy since they are larger than egg cells.
Which cell types will most likely communicate using electrical charges?
skin cells
nerve cells
red blood cells
white blood cells
