[Solved] Researchers are studying the coronary circulation in various healthy and diseased states. They measure blood flow and pressure (blue circle) in one of the epicardial coronary arteries of an experimental animal with cardiovascular physiology similar to that of humans. Then they clamp the artery to simulate 60% atherosclerotic stenosis and remeasure the flow and pressure distal to the lesion. Which of the following changes are most likely to be observed once steady state is achieved? A)A B)B C)C Unconditioned Response: A natural, automatic reaction to a stimulus that does not require learning to take place. Unconditioned Stimulus: In classical conditioning, it refers to a stimulus that naturally triggers a response without any prior learning. Discriminative Response: A behavioral response that differentiates between various stimuli, showing an ability to discern or discriminate between them. Conditioned Response: A learned response to a previously neutral stimulus that has become conditioned through association.
