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.

Answer:
One difference between these cells is plant cell has chloroplast but animal cell does not have chloroplast.
Another difference between these is that plant cell has cell wall but animal cell does not have cell wall.
Explanation:
Plant cell are known to cells that possess chloroplast. These chloroplast contain chlorophyll which enables the plants to manufacture their own food. Animal cell does not possess chloroplast which makes it impossible for animals to manufacture their own food.
Plant cell actually have cell wall and a cell membrane but animal cell does not have cell wall but only possesses cell membrane. The cell wall gives mechanical strength and maintains cell shape.
