Explanation:
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.
<span>Nucleus is the central organelle of the cell which encloses the DNA. Apart from the nucleus, there are few other organelles which have their own DNA.Mitochondria,power house of the cell has its own DNA.so the selected cell possess is mitochondria and chloroplasts.</span>
RNA travels to ribosomes, after leaving the nucleus, to perform translation and form amino acid with the help of tRNA
Answer - Theory
Reasoning - Your best bet and term to describe the evolution by natural selection is theory as to still scientific theory/research is still ongoing and changes can be made in a different direction.
