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.
...strong hydrogen bonds between the oxygen and hydrogen atoms of neighbouring atoms increases the amount of energy needed to cause water to change states.
Answer:
Option D.) Groundwater
Hope it helps pls mark me as BRAINLIST thanks :)
Heat creates energy... the atoms move faster and faster, which changes the state of matter.
for example:
if a solid is heated, it turns to a liquid
if a liquid is heated, it turns to a gas
hope this helps?
Rods work very well in darkness/ low light. Cones process colors.
