Answer:

they can differentiate into almost any other type of cell is the correct answer.

Explanation:

Stem cells are important because they can differentiate into almost any other type of cell.

A stem cell has the ability to differentiate and divide into different types of cells.

Types of stem cells

Embryonic stem cells

Adult stem cells

Induced pluripotent stem cells.

Properties of stem cells:

Stem cells are an unspecialized cell that can give to the specialized cell.

They can renew themselves.

They have the ability to differentiate.

Stem cells are used to treat many diseases as stem cells can replace the damaged cells.

Different types of diseases can be treated with the help of stem cells such as spinal cord injury, heart diseases, stroke, diabetes, macular degeneration, rheumatoid arthritis,leukemia,multiple myeloma,lymphoma,cancer, and neuroblastoma.

A DNA mutation changes the shape of the extracellular domain of transmembrane receptor protein A produced by the cell. Which of

Tatiana [17]

Explanation:

The extracellular domain of the transmembrane receptor protein acts as binding site for primary messenger molecule whereas the transmembrane domain holds the receptor within membrane and the cytosolic domain has intrinsic tyrosine kinase activity, all these helps in proper cell signaling

If because of any mutation there is change in shape of the extracellular domain then that molecule that normally binds to the receptor protein will no longer attach hence cellular response will be deactivated
