What was the main point of ivan pavlov’s experiment with dogs?

learning can occur when a conditioned stimulus is paired with an unconditioned stimulus.

Explanation:

learning can occur when a conditioned stimulus is paired with an unconditioned stimulus.

Russian physiologist, Ivan Pavlov was researching salivation in dogs in response to being fed. He inserted a small test tube into the cheek of each dog to measure saliva when the dogs were fed (with a powder made from meat).He discovered that when they saw or sensed food, they would produce saliva in expectation of feeding.

it also supports my hypothesis. if you rest first you can squeeze the clothespin more times. from the data i collected the average of the eight people concluded exercise makes your muscles more fatigued and less able to squeeze the clothespin compared to resting before squeezing.

i believe it's c. the trait for large beaks will be passed on to future generations through natural selection.

since eventually smaller beaks would have to find another source of food or even eventually just die out from the lack of food.
