Answer:
he Taeniae coil
Explanation:
The mesocolic,free and omental taeniae are collectively known as TAENIAE.
They are the 3 ribbon of smooth muscle of the ascending,transverse, descending and the sigmoid colon. Anatomically their longitudinal contractions give the <u>natural</u> bulges(HAUSTRAL) in the colon.
The Haustral helps in translocation of chyme to the next haustral, and aiding the mixing of chyme for water absorption in the colon,
The coil of these smooth muscles is under the parasympathetic nervous system through Sacral nerve (of the spinal cord) innervation.
The result of a cross between two agouti mice of genotype nnaa are albino offspring because mice with genotype nn are albino (pigment production is blocked by epistasis).
<h3>What is epistasis?</h3>
Epistasis is a genetic phenomenon where the presence of a gene variant alters a phenotype influenced by other genes.
A gene is epistatic when a variant (allele) can alter the expression of another gene in the same signaling pathway.
Epistatic interactions are very common in nature and many traits are influenced by this type of interaction.

Answer:
B. The chromosomes exchange genetic information.
Explanation:
Crossing over of tetrads during meiosis is very important for the exchange of genetic information.
This step of meiosis allows for each chromosome to be genetically unique and distinct from the others, creating genetic variation.
Crossing over does not double the number of chromosomes or reduce the number. The number of chromosomes stays the same.
So, the correct answer is B. The chromosomes exchange genetic information.
