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:
Alteplase is a thrombolytic agent that is used for the treatment of acute myocardial infarction for lysis of coronary artery thrombi. It should be used as an infusion in the first 6 hours of the beginning of the anginal symptoms. For example if you are a person over 70 kilos, 100mg are applied, in a 90-minute regimen like this: starting with a bolus of 15 mg, followed by an infusion of 50 mg for 30 minutes and 35 mg for 60 minutes.

Answer:
There are various reasons.
Explanation:
very cold temperatures - the water can be colder than expected, even in warm weather
hidden currents - there can be strong underwater currents, which can trouble even the most confident of swimmers
reservoirs are often very deep - it is difficult to estimate depth and they can be deeper than people expect
there may be hidden debris or underwater hazards which can cause injury, including weeds and plants which can entangle people under the water
if it’s polluted it could make you ill
it can be very difficult to get out (especially steep slimy banks)
there are no lifeguards on duty
the remoteness of some of these places can also hamper and delay rescue attempts
I hope that helped!
