Answer: The fight-or-flight response is most clearly associated with the release of epinephrine into the bloodstream.
Any physiological reaction occurring due to something which frightens physically or mentally is fight-or-flight response. In order to produce the fight-or-flight response the hypothalamus activation of the adrenal cortical system and sympathetic nervous system takes place. On receiving the signal from hypothalamus the sympathetic nervous system makes the actions of body speed up or gets tensed and body is in an alert condition.
The impulses are sent by the sympathetic nervous system to the smooth muscles and also glands. As a response to it epinephrine or adrenaline and the norepinephrine or noradrenaline is released by the adrenal medulla in the bloodstream. These stress hormones thus bring about changes in the body such as increase in blood pressure and heart rate.
<span>If you inherit the genotype AO for blood from your parents, you have blood type A. Regarding blood types, there are three possible alleles: A, B, and O. Both alleles A and B are dominant to allele O. So, if a person has the genotype AO, allele A will mask the effect of allele O, and the person will have blood type A.</span>
The frameshift mutation of a gene can be reversed by using a mutagen like intercalating agent.
<h3>
What is the mean of intercalating agent?</h3>
In organic chemistry, embolism is that the insertion of molecules between the placoid bases of desoxyribonucleic acid (DNA).This method is employed as a way for analyzing polymer and it's conjointly
the premise of bound forms of poisoning. A substance that inserts itself into the polymer structure of a cell and binds to the polymer. This causes polymer harm. In cancer treatment, polymer intercalating agents might kill cancer cells by damaging their polymer and stopping them from dividing. The frameshift mutation of a cistron may be reversed by employing a agent like intercalating agent.
