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.
An operational definition is used for a behavior so that the
behavior can be properly described and understood. Without an operational
definition, it would be difficult to describe behavior without being subjective.
Therefore, behavior cannot be understood and cannot be correctly addressed. It
is also important to understand how behavior functions so that the antecedents
and consequences of behavior can be observed. Thus, what reinforces or affects the
behavior can be better understood. Lastly, an operational definition is
objective and specific, therefore, behavior can be described across different
settings and times.

Answer: Metamorphic rocks started out as some other type of rock, but have been substantially changed from their original igneous, sedimentary, or earlier metamorphic form. Metamorphic rocks form when rocks are subjected to high heat, high pressure, hot mineral-rich fluids or, more commonly, some combination of these factors.
