Question

which of the following is true about the cells of the human body?
a. environmental factors cannot influence the development of a cell.
b. all cells in the human body are shaped like discs and contain one nucleus.
c. different cells perform different functions within the human body.
d. the genetic information contained in cells differs between cell types.

Explanation:

Environmental factors can influence cell - development, so A is false. Not all human cells are disc - shaped and have one nucleus (e.g., nerve cells), so B is false. All cells in the human body contain the same genetic information, but different genes are expressed in different cell types, so D is false. Different cells in the human body have specialized functions, such as red blood cells for oxygen - transport and nerve cells for signal - transmission.

Answer:

C. Different cells perform different functions within the human body.
