While studying the role of saliva in digestion of dogs Pavlov accidentally discovered Classical Conditioning, which denotes a <span>learning procedure in which a biologically potent stimulus (e.g. food) is paired with a previously neutral stimulus (e.g. a bell).</span>
In the case of the dogs Pavlov observed, the salivation was the unconditioned response and the salivation was the conditioned response.
Answer:
Concentric circle model
Explanation:
The concentric model was proposed by Burgess. This model defines different social people to live in an urban area. This is a very famous model related to metropolitan cities for development. Many of the social groups are based on their socioeconomic status that stands from central part distance to downtown.
This model is called the concentric model because it defined all social groups in the shapes of the ring from the center part to the outer part. It is also called the Burgess model. The human geography and urban geography involve it in the development of urban metropolitan cities.

-
Spain's transfer of territory to France (1st October 1800)
-
Louisiana Purchase (4th July 1803)
-
Pike's expedition in the Southwest (15th July 1806)
The further explanation is given below.
Explanation:
In the above questions, the events are missing. Please find the attachment of the full question.
- Spain as well as the US signed the Pinckney Treaty agreement to establish the boundaries throughout northern Europe between some of the US and the Spanish nations, as well as to control ruling on either the Mississippi River.
- With either the Treaty of San Ildefonso during 1800, Spain gave colonial territory across Louisiana towards France.
- The Louisiana Purchase seems to have been a contractual relationship one where France transferred to either the US in 1803 2 144 476 km² of colonial lands throughout America for something like a selling costs of $15 million.
- Pike's exploration seems to have been a future operation undertaken throughout 1806 until 1807, on support including its US government, to investigate the Louisiana purchase which the US had bought from either the French throughout 1803.
the answer is: A cognitive psychologist enrolls undergraduate students for a computer-based study about the effect of mood on problem-solving behaviors.
Here the requirement for research with human subjects according to the Fed :
"Obtains information or biospecimens through intervention or interaction with the individual, and uses, studies, or analyzes the information or biospecimens; or Obtains, uses, studies, analyzes, or generates identifiable private information or identifiable biospecimens."
The experiment on this ption fulfill the criteria because:
- The experiment should use studies or analytics to obtain some sort of private information from the subjects. (such as their mood)
- The experiment should make some sort of intervention that can be used to measure its hypothesis. (in the case above, the researchers could put the subject under a certain level of stress before telling them to solve a set of problems)
- The researchers need to interact with the subject in a certain way. (since the researchers meet the undergraduate directly, it's considered as an interraction)
