Answer:
The correct answer is option d.
Explanation:
An illustration of epigenetic change is a microbe, which can stimulate modifications in the host DNA, causing suppression of defenses or weakening of individual cells. Epigenetic changes modify the physical composition of DNA.
One of the examples of epigenetic change is DNA methylation. DNA methylation refers to the supplementation of methyl group, which inhibits some of the genes from getting expressed. One of the conditions of DNA methylation is cancer.
In the majority of cancer, the tumor cells go through global hypomethylation. The tumor suppressed genes seem to turn highly methylated in the conditions of cancer.

1. interphase -(B)cell grows and
duplicate.
2. Mitosis- .(A) DNA separate forming two new nuclei.
3. Cytokinesis- (C) Two new cells separate.
the autonomic (involuntary) nervous system controls the rate at which the heartbeats. sympathetic (fight or flight) signals speed up the heart’s rate while parasympathetic (rest and digest) signals slow it down. The part or parts of the heart that forms sympathetic and parasympathetic neurons form synapses is called cardiac plexus.
Cardiac plexus is a plexus of the nerves that are present at the base of the heart and is divided into superficial and deep part. The sympathetic and the parasympathetic nerves form synapses with heart in the form of cardiac plexus.
The sympathetic nerves are responsible for activating flight or fight mode while parasympathetic nerves are responsible for restoring the normal body state.

Answer:
Short answer is primers are partially complementary.
Explanation:
Forward primer: 5'-AGTCTACTCGTAACCGGTTACC-3'
Reverse primer: 5'-TAAGGCATCATGGTAACCGGTT-3'
When we write reverse primer 5' to 3' we can easily see that
3'-TTGGCCAATGG---5' is complementary to the forward primers'
5'---AACCGGTTACC-3' sequence. So instead of binding to the template DNA these primers might bind each other resulting with reduction of efficiency of DNA amplification.
