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.

When a human red blood cell is placed in a hypotonic environment (like distilled water), it will
Ksivusya [100]

Answer:

C shrink

Explanation:

a hypertonic solution has more solutes than the intracellular environment, so water will leave the cell to try to achieve equilibrium. If enough water is lost, the cell will take on a wrinkled or shriveled appearance. In red blood cells this is called crenation and the surface of the cells take on a scalloped appearance. A high amount of water loss can be damaging or even fatal for a cell.
