Answer:
The correct answer is d Insulin initiates a protein kinase cascade that utilizes glycogen synthase kinase.
Explanation:
During muscle contraction glycogen degradation occur which result in the formation of glucose-6-phosphate that is supplied to the muscle.This total phenomenon is signaled by steroid hormone epinephrine that deals with the breakdown of glycogen.
But the peptide hormone insulin exhibit the opposite effect that to stimulate glycogen synthesis by activating the catalytic activity of glycogen synthase through the help of phosphorylation by glycogen synthase kinase.
Of the possible types of relationships - parasitism is the only one which doesn't really represent a symbiotic type of a relationship. All of the other ones here (mutualism, commensalism and competitive exclusion) are some form of symbiotic relationship.
The speciation process is best defined as the development of a new species (c).
