Answer and Explanation:

The mechanism of action of statins begins with the inhibition of a protein called HMG-CoA reductase, allowing its substrate to accumulate in the body and promote cholesterol reduction. At that moment, a transporter called OATP (Organic Anion Transporting Polypeptides) takes statins to the epatic tissue where they will be transformed and metabolized until they are eliminated through bile. This elimination is influenced by the P-glycoprotein, which is the main cause of the efflix presented by the bili. This process can get help from other molecules like some protease inhibitors, digoxin and cyclosporine.

Vanyuwa [196]
The type of learning that the young sea otter used to be able to perform this task is social learning.
This means that the young otter learned what it is supposed to do from its surroundings - and what is surrounding it is its society of other otters. It is social learning because the otter didn't learn on its own that it needs to break open shells in order to eat what is inside, but rather it saw what the other otters were doing and thus learned it.
