The term Southern Oscillation most nearly refers to a reversal of wind direction
Answer: Option D
<u>Explanation:
</u>
Southern Oscillation, a component of the atmosphere in one large-scale interaction called El Niño / ENSO. The equatorial cycle fluctuates after irregular periods of about many years in response to alter in atmospheric pressure in the tropical Indo-Pacific.
With the weakening of the east-west wind during the southern oscillation phase, warm water may slide back west, increasing the flow of the equator up. Surface water temperatures and sea levels fall west and rise east, which is why this event is called El Niño.

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.
