zimovet [89]

Answer:

b. to amplify the signal

Explanation:

A multi-enzyme phosphorylation cascade is a series of signaling events where one enzyme phosphorylates to another, then this last enzyme acts to phosphorylate another protein and so successively, thereby triggering a chain reaction that leads to the phosphorylation of hundreds or even thousands of proteins. A multi-enzyme phosphorylation cascade is known to increase the number of activated (phosphorylated) proteins at each step of the signaling cascade. Phosphorylation is a posttranslational modification capable of activating proteins during long periods, thereby a phosphorylation cascade also enables the activation of multiple proteins before these proteins become inactive again.

Why can’t the evolutionary relationships between certain species be explained thoroughly?
zmey [24]

Answer:  The species are poorly related to each other.

Darwin gave information for evolution as "descent with modifications" it involves a process in which species change and gives rise to a new species over generations. He proposed that the evolutionary history of life forms a branching tree with many level as a new species evolve. All species can be traced back to a common ancestor. Each newly evolved species will have one or more characteristics in common as that of the old species.

In species with no common ancestor will not have any similar characteristic in common such species cannot be evolutionary linked and cannot be placed and linked in an phylogenetic tree.
