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
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.

Where does the sedimentary rock chalk form? from the precipitation of minerals in shallow marine environments by the lithificati
Katarina [22]

The correct answer is an accumulation of microorganisms in deep marine environments.

Chalk rock refers to a pure form of limestone produced in tropical and warm seas about 100 million years ago in the Cretaceous period. The microscopic marine algae known as coccoliths thrived in the ancient seas. Their shells were comprised of calcite. With the death of the algae, their bodies sunk to the floor of the sea and sediment of chalk got deposited.

Over many years layers of chalk sediment got deposited and resulted in compaction of loose sediment into solid chalk rock.

What if the sun disappears one fine day ?
igor_vitrenko [27]

Explanation:

Sun plays an important role in our solar system especially planet like earth are dependent on sun for food, water and air. Sun helps to balance the ecosystem on earth.

Here is an assumption what would happen if sun disappear for one day only, it would be more curt if it disappear forever but from POV of one day below are certain consequences of such a situation over solar system,

  1. You might be thinking if sun disappear then we would be seeing the moon for a whole day but don't forget, moon don't have it's own light, it reflects the rays coming from sun if sun disappear then surely moon would be like a ball kept in dark.
  2. It would happen for the first time if an asian man calls to someone in Europe, usually when here is night there is day and vica versa, but this time both will have same appear (night only)
  3. There's a idiom in Indian Hindi language that says "seeing the stars during the day time" which we use when we are going through something worse that we see the stars during daytime, but this time every human being on earth will see the stars during daytime, do not forget stars have their own light, they are not sun dependent.
  4. For the first time Night Blooming Jasmine will bloom and spread it's fragrance for 24 hours.
  5. Often when the earth revolves around its axis, a certain part of it receives light from the sun.But for the first time the earth will rotate around its axis without the sunlight falling on any part.
  6. people who are not allowed to go out of the house at night time can now enjoy the night out in the day too.
  7. Those trees and plants who slept in the hope that they would cook food in the morning with sunlight, they would not even know that their food has gone missing.
  8. Our ozon layer will have it's first leave from his duty.
  9. The bad thing is for the patients of night blindness, they will not be able to see this imaginary scene.
