These fibers provide vis- ceral motor (parasympathetic) innervation to the viscera. The only cranial nerves that transmit parasympathetic fibers are the oculomotor, facial, glossopharyngeal, and vagus nerves.
Answer:
b. The two bacterial strains have different phenotypes.
Explanation:
In genetics, the trait that is expressed is often referred to as the dominant trait and it can also be expresssed phenotypically.
Since one of the bacteria produces the inducer, it therefore means that bacteria has the dominant strain for the regulatory inducer while the other bacteria might have the strain but since it is not expressed phenotypically, it is as a result not dominant.
Phenotype refers to the physical appearance of an organism as a result of the interaction of its genes with the environment. Examples of phenotypic expresssions are hair colour, skin colour, height, etc.
Answer:
The heart valves
Explanation:
The heart valves prevent blood from flowing in the wrong direction in the heart. The valves are held in the proper place because of the chordae tendinae.
Answer:
Anaphase
Explanation:
During anaphase, cytokinesis – which is the pinching off of the cell membrane – the organelles which duplicated during the prophase are roughly equally divided between the two dividing cells. This is because these organelles are well distributed across the cytoplasm of the mother cell.
Natural Selection helps animals survive in their habitats and they have adaptations to help them survive better.
