Answer:
The diagram, which illustrates a form of genetic recombination, shows that each allele is granted separately to the daughter cells, which is an example of independent assortment.
Explanation:
Crossing over, fertilization and independent assortment are methods of genetic recombination. The diagram (image) states that A-a and B-b are alleles for different characteristics, found in genes and chromosomes.
Independent assortment it was observed for the first time by Gregory Mendel, during his experiments with peas, describing that alleles -the portion of genes that contains variations of specific characteristics- are unrelated to each other and can be distributed independently in the daughter cells.
In this case, thanks to independent assortment, each parent can pass the characteristics of their genotype separately to the offspring -which will have shared characteristics of both- producing genetic variation in species.

Answer:
Medulla Oblongata
OR
Thalamus
Explanation :
The medulla oblongata: Contains centers for the control of vital processes such as heart rate, respiration, blood pressure, and swallowing.
So it could be either.
The thalamus: is a sensory relay in visual, auditory, somatosensory, and gustatory systems.
They both are not directly involved because the medulla oblongata is not anything to do with the brain and the thalamus is to do with the brain but another part of the brain. The thalamus sends information that can be stored in the memory, so it is not direct involvement.
Side note:
I encourage you to take both possibilities into account.

The specific adaptation of the sloths to their niche is energy conservation: they survive by trying not to loose any energy and trying not to move too much. They have less muscle because they don't need it: their adaptation is to move less. So the correct answer is to a) conserve energy.
