Answer:
The correct answer is - divergent.
Explanation:
A divergent plate boundary is plate boundary that is form by the sepration of the two distinct tectonic plates away from one another and result in the forming the ranges known as oceanic spreading ridges.
This type of plate boundary occurs due to the earthquack or volcanic erruption of from the mantle to surface of the earth. This magma or rises and forms oceanic crust by the solidifying of the moleten rocks.
The answers are;
The muscular contractions are wave-like
The muscular contractions are entirely involuntary
This action is called peristalsis.
It is powered by the expansion and contraction of the smooth muscles present in the esophagus. It is controlled by the sympathetic activity of the autonomic nervous system hence
the movements are involuntary.
The <em>TYR </em>gene is responsible for the production of the enzyme tyrosinase which is crucial in the production of melanin which is primarily responsible for skin pigmentation and for pigmentation of other organs. In albinism, there is mutation of the <em>TYR </em>gene therefore there will be no transcription of DNA to mRNA and no translation of mRNA to the enzyme tyrosinase leading to its deficiency. The deficiency of tyrosinase will eventually lead to the absence of melanin and ultimately, the absence of pigmentation in an organism.
