Dr. Graham exposes rats to a vanilla scent prior to receiving a food pellet in the left corner of their cage, but provides no fo
od after exposure to a lemon scent. After several trials, upon smelling a vanilla scent, the rats wait at the far left corner of the cage regardless of whether a food pellet is present. However, they do not wait in the far left corner when exposed to the lemon scent. What is the unconditioned stimulus in the experiment? a. food pellet
b. vanilla scent
c. lemon scent
d. left corner of cage
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>Roughly 5.6 years would be added to the average lifespan of the U.S. population. The test's lifespan increased from 719 to 770, or by 1.071. Multiplying the average lifespan by this amount would equal 84.609.</span>
since one mole is 6.022×10^23 atoms, one mole of silver is 6.022×10^23 atoms and one mole of tin is 6.022×10^23 atoms. so one mole of tin has the same number of atoms as one mole of silver
