Test Review 1-Special, Uni, Stem Cells

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.
