The genetic variation occurs due to induced changes to the genome from environmental factors, fertilization of two haploid gametes during gamete fusion. The correct options are D and E.
<h3>What is genetic variation?</h3>
The presence of differences in gene sequences between individual organisms of a species is referred to as genetic variation. It allows for natural selection, which is one of the primary forces driving life's evolution.
The genetic variation occurs due to induced changes to the genome from environmental factors, fertilization of two haploid gametes during gamete fusion.
Thus, the correct options are D and E.

Answer:
ATP is produced most efficiently by structure C.(mitochondria)
Answer:
A) Faster blood flow: A faster blood flow means the heart pumps blood with more power. Pumping blood to fast for too long can damage the heart muscle and interfere with its normal electrical signals, which can result in a dangerous heart rhythm disorder.
B) Infection: infection is caused by invasion of the body by external microorganisms. Disease can arise if the host's protective immune mechanisms are compromised and the organism inflicts damage on the host.
C) vomiting: This is an involuntary, forced expulsion of stomach contents usually through the mouth or nose. Body's reaction can be aspiration, electrolyte and water loss, damage to the enamel of the teeth, tear of the esophageal mucosa etc.
D) High blood pressure: This is due to the heart pumping blood at high pressure putting a strain on the walls of the blood vessels. In some cases, people with high blood pressure may have a pounding feeling in their head or chest, a feeling of lightheadedness or dizziness, or other signs.
The question is incomplete. However, if we consider this cell as human cell - the cell contain 23 pairs of chromosomes.
Answer:
Chromosomes consists of the constricted DNA associated with the proteins. Different species has different chromosome number. Two main types of chromosomes are heterochromatin and euchromatin.
The human cells contain the 23 pairs of chromosomes or 46 chromosome. If the cell divides by the process of mitosis than the chromosome number will be same in parent as well as the daughter cell. The daughter cell 23 pairs of chromosomes. If the cell divides by the process of mitosis the cell has 23 chromosome number as the meiosis reduces the chromosome number upto half.
