Answer:
"The American Robin is the largest, most abundant and broadly distributed thrush in North America. The presence of this songster in the backyard setting, together with its loud, musical voice, make it one of the most recognizable birds in North America. Indeed, the American Robin has been described as "America's favorite songbird" (Young 2012)".

Answer:
It decreases the levels of cAMP in the cell, repressing transcription from the lac operon.
Explanation:
When glucose is absent, cAMP serves as coactivator binds to CRP, the catabolite gene activator protein. The CRP-cAMP complex binds to the site near the lac promoter and stimulates the expression of the operon by RNA polymerase many folds.
Catabolite repression refers to inhibition of the synthesis of enzymes of lactose catabolism when glucose is present as an energy source. In the presence of glucose, synthesis of cAMP is inhibited resulting in its lower cellular concentration. The lower cAMP levels do not allow the binding of cAMP and CRP. The result is reduced expressed of lac operon.
Given what we know, we can confirm that if a cancer medicine wishes to stop cellular division, it must target the Centrioles of a cell.
<h3>What are the Centrioles of a cell?</h3>
- The centrioles are cylinder-shaped organelles made up of microtubules.
- Their function is to organize the contents of the cell before cellular division.
- This is done to ensure that once the cell divides, its contents are split evenly to each daughter cell.
- They also play a role in initiating the cellular division process.
Therefore, given the role of the centrioles in organizing the contents of the cell for cellular division, as well as initiating the first part of cell division, we can confirm that in order for a cancer medicine to stop cell division, it must target the centrioles.

The answer is A. Rabbits eat grass. The snakes eat the rabbits and the hawks eat the snakes. So if rabbits died off, so would the snakes, and the hawks. Because both of their food sources would deplete. And grass would flourish.
