When half of the earth is facing the sun we have daylight.
<u>Explanation:</u>
The earth rotates about its in every 24 hours. When the earth's one of the sides faces the sun, then days occurs. When the side of the earth is far away from the sun, then night occurs. The earth rotates in an anticlockwise direction when we view form the north pole. The daylight sweeps the darkness from east direction to that of the west across the world.
All planes have day and night times because they all rotate about their axis. The day and night cycle time or the length differs for each planet. this is because the speed in which they rotate differs. The planet mars has the same day and night cycle length as earth.
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.
It contains a cellular membrane which separates the interior of the cell from its environment.
