One possible result of chromosomal breakage is for a fragment to join a nonhomologous chromosome. What is this type of chromosomal alteration called <u>translocation.</u>
A chromosomal fragment is translocated when it is moved from one genomic sequence to another. Around two nonhomologous chromosomes, a translocation mechanism takes place in order to permit the interchange of fragments created by chromosomal breakage.
When a segment of one chromosome separates and affixes towards another chromosome, translocation takes place. If there is neither genetic material growth nor loss in the cell, such a form of rearrangement would be referred to as balanced.

Answer:
sympathetic stimulation
Explanation:
Under stress or emergency conditions, the preganglionic neurons of the sympathetic division release acetylcholine. Acetylcholine stimulates secretion and release of epinephrine and norepinephrine from the adrenal medulla. These hormones enhance the effects of the sympathetic division of the autonomic nervous system (ANS) during stress. Epinephrine and norepinephrine augment the fight-or-flight response as they increase the heart rate and force of contraction, the output of the heart, and blood pressure. They also increase blood supply to the heart, liver, and adipose tissue. The airways to lungs become dilated and there are increase blood levels of glucose and fatty acids.
