What are the mechanisms by which aneuploidy and polyploidy are caused? What are the mechanisms by which aneuploidy and polyploid
sleet_krkn [62]

The correct answer is:

The principal cause of aneuploidy is chromosome nondisjunction during mitosis or meiosis. Polyploidy in nature can result either from the duplication of euploid chromosome sets from a single species or from the combining of chromosome sets from different species.  

Aneuploidy is a phenomenon when there is the presence of an abnormal number of chromosomes in a cell (an extra or missing chromosome). Usually it appears as a result of improper cell division (chromosomes don’t separate) and it can cause many genetic disorders.

Polyploidy refers to a state when there are more than two sets of chromosomes (one from mother one from father). Triploid (three sets of chromosomes) and tetraploid (four sets of chromosomes) chromosomes are examples of polyploidy. This phenomenon is most common in plants.

schepotkina [342]

Answer:

The correct option is a) "decrease the amount of GTP to inhibit microtubule elongation and block secretion"

Explanation:

Since microtubules play a critical role in transporting secretory vesicles, preventing it from elongating will keep it from performing this function. Completely eliminating the microtubules from the cell as suggested in option d will harm the cells and other processes in it because the microtubules also have an integral part to play in maintaining cell shape & structure.

sertanlavr [38]

Answer:

1. kidneys 2. Lungs 5. Pancreas

Explanation:

The body's balance between acidity and alkalinity in the human body is regarded as the acid-base balance which is measured on the basis of the pH and the concentration of carbon dioxide and bicarbonate in the blood. The organs that controls acid-base balance are lungs, kidneys and pancreas. Theses organs control blood pH by releasing carbon dioxide from the lungs because it is a waste product slightly acidic in nature and excreting excess of acids and bases from the body.
