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>
Among the possibilities you've listed, the most impact on a person's exercise habits will be found in the community. People from our community are the ones who often force us to go and exercise when we usually wouldn't do it ourselves. When we have a supportive community, this makes the difference between working out and not working out sometimes.

Answer:
Explanation:
Fracture healing is a complex process that requires the recruitment of appropriate cells and the subsequent expression of appropriate genes at the right time and in the right anatomical location. Bones are richly supplied with blood vessels. Most apparent are the nutrient arteries (one or more per bone) that arises from adjacent arteries outside the bone and enter the bone through the nutrient foramina. The nutrient artery divide in the medullary cavity into ascending and descending branches. Blood get to the bone cells through the haversian systems or osteons which are microscopic canal systems that house the blood vessels. The end of bones are supplied by epiphyseal and metaphyseal arteries.
