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.

Heat causes changes in the temperature of objects
1. Any cone-bearing trees would release their seeds. These trees make the fires advantageous to their species by having the seeds "explode" when heat touches the cones.
2. The ashes from the burned trees would help nourish the released seeds.

<span>Lysosomes are cell organelles that broken down or digest the dying and old cell organelles and recycle the materials that are on it.
Cell is the most basic unit of matter that can carry out all the processes of life however not all cells are alike.The different structures found within the cell is called the organelles and are assigned to perform specific function in the specific cell. It is also said that organelles maintain the life of the cell. The organelles of a single cell like the organs of a multicellular organism is very essential for the survival of the body. The presence of organelles in both unicellular and multi-cellular organisms are very essential in orde to maintain life and carry on with its individual functions.</span>
