Answer:
In Pavlov's classic study on classical conditioning, the bell was the <u>neutral stimulus </u>before conditioning and the <u>conditioned stimulus</u> after conditioning had occurred (option C).
Explanation:
Classical conditioning, proposed by Ivan Pavlov, establishes that two stimuli -one unconditioned that produces a response and one neutral- when associated, convert the neutral stimulus into a conditioned one with a response.
Pavlov's famous dog experiment laid the foundations of classical conditioning:
- A dog is capable of salivating at the sight of food.
- The same dog does not react to a bell.
- When the dog is shown the food and the bell rings, in repeated opportunities, the only sound of the bell will make it salivate, what is a conditioned response.
The bell, a neutral stimulus, and salivation have become a conditioned stimulus and response, respectively.
Regarding other options:
<em> a. A conditioned stimulus does not lead to an unconditioned one.
</em>
<em> b. A neutral stimulus does not result in reinforcement.
</em>
<em> c. Pavlov's experiment did not demonstrate the conversion of a conditioned stimulus into a neutral stimulus.</em>

Answer:
lymphocytes
Explanation:
Lymphocyte is a type of cell that is part of the body's immediate defense, acting against cancer cells and viral infections. Also, these cells are very important in wound healing. Slower healing of an injury is best explained by temporarily reduced lymphocyte production.
The concentration of these cells in the blood depends on the individual's physical condition: in cases of immunodeficiency, the concentration is low (lymphopenia); when there are infections or rejection of transplants, it increases (lymphocytosis). Lymphocyte count is a widely used test for monitoring diseases and infections such as those caused by HIV.
