Answer:

a. ​food pellet

Explanation:

In classical conditioning, an unconditioned stimulus is the stimulus that naturally elicits an unconditioned response. The unconditioned stimulus is usually paired with a neutral stimulus, and after pairing with a neutral stimulus, the neutral stimulus becomes a conditioned stimulus that elicits a conditioned response alone.

In the experiment described above in the question, <em>the unconditioned stimulus is the food pellet,</em> which naturally elicits the response of the rat to wait at the far left corner of the cage. The neutral stimulus which is paired with the food pellet is the vanilla scent, which now becomes the conditioned response, when paired alone.

Setler79 [48]

Answer:

The correct answer is A the compound is a competitive inhibitor

Explanation:

Competitive inhibitor competes with the substrate to bind to the active site of the target enzyme and after binding to the active site the inhibitor slow down or stop the reaction catalyzed by that enzyme.

          Competitive inhibitor basically effects the Km value of the enzyme thus decreasing the activity of the later.

           Increasing the substrate concentration displace the inhibitor from the enzyme"s active site thus reducing the inhibitory effects of the later thus increasing the activity of the enzyme.
