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:
Sugars are the most common substrate of fermentation, and typical examples of fermentation products are ethanol, lactic acid, carbon dioxide, and hydrogen gas (H2). However, more exotic compounds can be produced by fermentation, such as butyric acid and acetone.
Explanation:
D - Enormous energy requirements
Answer:
The correct answer is as showed in the Explanation
Explanation:
Seismic waves are waves of energy that are produced due to Earth's layers movement, such as the ones occurring during earthquakes. Scientists developed an early warning system to determine when an earthquake is going to take place by analyzing the behavior of two types of waves: P waves and S waves. P waves are the ones that travel faster and are produced first, they travel in an exact opposite direct of where the earthquake is produced. On the other hand, s waves or secondary waves are slower and travel in a perpendicular way. Scientist detect when these waves are generated in specialized centers.
