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>
All of those are symptoms of heatstroke
Answer:
B. Nutritionist
Explanation:
Calories are a unit for the measurement of the amount of energy in different foods and drinks.
Pharmacists are responsible for the distribution of medication, which is not measured in calories so it is not A.
X-ray technician organise X-rays which scan the insides of people's bodies (most commonly bones) so they do not use calories.
Finally life technicians identify and collect loving organisms to study so they don't use calories either.
A nutritionist's is to evaluate the chemical make up of different foods i.e. How much energy hence calories, and how they work with different people's bodies, therefore B is correct.

Digestive system is the system of organs which digest food. Human digestive system is consisted of the gastrointestinal tract and the accessory organs of digestion. Accessory organs of digestion are: the tongue, salivary, glands, pancreas, liver and gallbladder. The digestion in this system has many stages, and the first one starts in mouth, and it is called oral cavity. D<span>igestion means breakdown of food into smaller and smaller and smaller components which can be absorbed and assimilated into the body...</span>
Different types of drugs affect your body in different ways, and the effects associated with drugs can vary from person to person. How a drug effects an individual is dependent on a variety of factors including body size, general health, the amount and strength of the drug, and whether any other drugs are in the system at the same time. It is important to remember that illegal drugs are not controlled substances, and therefore the quality and strength may differ from one batch to another. Drugs can have short-term and long-term effects. These effects can be physical and psychological, and can include dependency. You may act differently, feel differently and think differently if you have taken drugs. And you may struggle to control your actions and thoughts. You might begin to use drugs without thinking about any harm to your body. You might think drugs won't become a problem because you are only a casual user. The more you take a drug, the more likely you are to build up a tolerance to its effects. This can lead to the need to take larger doses to obtain the effects of the drug. For this reason, evidence suggests that after prolonged use, many drugs can cause dependence. Drug dependence can quickly begin to affect your psychological and physical health, and can also affect your work and social life. It is important to remember that there is no safe level of drug use. Be careful when taking any kind of drug.
