The defecation reflex involves two postive feedback loops. these loops are the stretch receptors in the rectal walls and the sacral parasympathetic system. Defecation reflex empties the rectum by peristaltic movements push fecal matter from the sigmoid colon into the rectum. Then this distension of the rectal walls stimulates stretch receptors which results in defecation.
The answer is C. Golgi Apparatus
Tubes for Transporting Food-carrying tubes Phloem Water-carrying tubes Xylem Sugar is produced In the leaves. The food-carrying tubes transport this sugar from the leaves to the other parts of the plant. The root hairs found on the roots Take in water and mineral salts from the soil.

Salad dressing contains fat, a lipid.
Nicole is probably guilty.
The type of mutation that occurred here is an inversion of three nucleotide bases (Option A).
<h3>What is an inversion?</h3>
An inversion is a type of mutation where linear order of nucleotide in the mutated sequence is inverted.
In this case, we have an inversion that involves the following bases (bold highlighted) AATCGC TAC GCACGTCAG and AATCGC CAT GCACGTCAG.
In conclusion, this mutation is an inversion of the genomic sequence (Option A).
