Answer:
The correct answer is: A. The genes for insulin production are not activated in heart cells.
Explanation:
<u>DNA </u><u>is present in practically every cell in an organism</u>, but not every cell performs the same tasks as the rest. This happens because genes in the DNA <u>code for different types of proteins</u>, from enzymes to transporters, that impact greatly on the <u>function</u> of a cell; and these genes can be activated or inactivated which will directly correlate to the type of cell and the function that it has.
<u>If the cells in the pancreas can produce insulin but the cells in the heart can't it's because the cells in the heart have the genes for insulin production inactivated</u>.
The amount of mitochondria and ribosomes does not directly affect the production of insulin.
