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.

dolphi86 [110]

The species had the same fundamental niche, but the high-altitude species was occupying a perceived niche, as it was inhabiting a different ecosystem, with different adaptations, but being the same species.

<h3>Why is the perceived niche considered a subset of the fundamental niche?</h3>

Well, as we know, the perceived niche is smaller than the fundamental niche, in other words it is a specific portion of the fundamental niche, so it is considered a subset of the fundamental niche.

With this information, we can conclude that the species had the same fundamental niche, but that the high-altitude species was occupying a perceived niche, as it was inhabiting a different ecosystem, with different adaptations, but being the same species.
