Answer:
These reactions are collectively called the urea cycle or the Krebs-Henseleit cycle. Ammonia is a toxic product of nitrogen metabolism which should be removed from our body. The urea cycle or ornithine cycle converts excess ammonia into urea in the mitochondria of liver cells.
Marie is experiencing the: Sympathomimetic effects (fight-or-flight state).
The sympathetic nervous system is a component of the autonomic nervous system, managing the activity of visceral organs and the automatic functions of the body, such as breathing or beating of the heart. The sympathetic nervous system is involved in many unconscious physiological activities through two neuromodulators of the catecholamine family: adrenaline, but especially norepinephrine (fight-or-flight hormones).
* It accelerates the metabolism and is activated for example in case of danger or fear, to prepare the individual to escape.
* It affects the cardiovascular system: it increases the heart rate and induces peripheral vasoconstriction, causing an increase in blood pressure.
* At the digestive level, it slows the muscular contractions of the intestines but promotes the release of glucose by the liver.
* It also has a bronchodilator effect, that is to say, it causes the increase of the diameter of the bronchi.
Answer:
The cell cycle best repairs organism from a puncture wound.
Explanation:
Repairing in organism means restoration of damaged tissue and its functioning. In a cell cycle, a tissue is repaired through the process of Mitiosis in cell division. It helps in growth of cell.
Through this process identical cell copies are produced by which the punctured wound or damaged tissue is replaced. Thus, cell cycle is seen in playing an important role in repairing an organism.
Answer:
D) Neither of the parental genes is dominate over the other.
Explanation:
<em>Since the trait on the offspring is a mixture from both parent, it means that neither of the alleles from both parents is completely dominant over the other. Instead, each of the alleles contributes equally to the trait of the offspring.</em>
This effectively explains the fact that each trait exhibited by offspring is a blend of the traits from the two parents.
The correct option is D.
