jenyasd209 [6]

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.

wariber [46]

Answer:

False

Explanation:

Beryllium is used in alloys with copper or nickel to make gyroscopes, springs, electrical contacts, spot-welding electrodes and non-sparking tools. Mixing beryllium with these metals increases their electrical and thermal conductivity.  Other beryllium alloys are used as structural materials for high-speed aircraft, missiles, spacecraft and communication satellites.  Beryllium is also used in nuclear reactors as a reflector or moderator of neutrons.
