I would select A because cells have to divide into smaller cells depending on where they are.
The provided question lack the essential part which is required to answer the question, however the correct part is attached with with the question as image.
Answer:
From the provided punnett square it is clear that the genotype of parents are Rr for each. On this basis offspring which is maria that can be either RR, Rr, or rr. Maria have chances to get RR= 25%.
There can be no 100 surety of the phenotype of maria as there is 25% chances of rr and 75% of ability of tongue rolling.
to get Rr=50% and rr = 25%
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:
C. Meiosis produces new combinations of chromosomes.
Explanation:
Compared to mitosis, meiosis divides TWICE and has EIGHT stages of rather than mitosis with the regular four stages.
The end result in Meiosis produces haploid cells in which half of the amount of chromosomes are produced in each individual cell, therefore Meiosis produces new combinations of chromosomes.
A. is incorrect because Meiosis does NOT create genetically identical cells.
B. is incorrect because Meiosis creates a HALF set of chromosomes (or just half than the original amount).
D. is incorrect because DNA is not produced during meiosis.
Commensalism is when a parasite feeds of of something, but doesn't hurt the host.
