Cell Differentiations in animals

Cells differentiate to perform different functions because

• all genes are turned on inside that cell

• all genes are turned off inside that cell

• different genes are turned on inside that cell

• different genes are turned on or off inside that cell

During the process of differentiation

• all sections of DNA are activated to determine the structure of a body cell

• ONLY ONE section of DNA are deactivated to determine the structure of a body cell

• only specific sections of DNA sequence are activated to determine the structure and functions of a body cell

• specialized cells

• differentiated cells

• nerve cells

• stem cells

Which best explains why muscle cells are different from blood cells?

• Muscle cells are produced by the brain, but blood cells are produced by the heart. 

• Different genes are activated in muscle cells than in blood cells. 

• Muscles cells experience different environmental influences than blood cells. 

• A mutation occurs during the development of muscle cells but not in blood cells. 

Answer explanation

Muscle cells and blood cells differ in gene activation.

Which is true about embryonic stem cells?

• They no longer divide, their cell type is set and cannot change.

Cell differentiation is critical during embryonic development. The process of cell differentiation results in the production of many different kinds of specialized cells. This process is most directly influenced by

• DNA

• Lipids

• Carbohydrates

• ATP

What is the function of nerve cells?

• Allow for gas exchange to happen.

• Transport oxygen throughout the body.

• Control DNA expression.

• Transmit electrical signals to different parts of the body.
