Answer:
I believe the answer is B.
Explanation:
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:
The lead whose positive electrode is placed on the left leg is II or DII (option C).
Explanation:
The electrocardiogram or EKG is a method of recording the electrical activity of the heart, useful for the diagnosis of diseases related to rhythm and heart rate. The 12-lead EKG is commonly used.
The electrode located on the left leg corresponds to the positive pole of the II or D-II lead, a bipolar peripheral lead whose negative pole is on the right arm. The electrode on the left leg is also the positive pole of the D-III lead, which goes to the left arm, and of the monopolar AVF lead.
The other options are not possible because:
- <em>AVR and AVL are monopolar leads located in the right and left arms, respectively.</em>
- <em>I or D-I corresponds to the bipolar lead whose poles are located between both upper extremities.</em>
The answer is the upper back muscles. Hope I helped!
A set considered the amount of repetitions that were completed in one exercise. A repetition is the each individual time that the person doing that exercise.
Example: I do a set of 4 bicep curls. Each set will be 10 repetitions. That means I will do 10 bicep curls, 4 different times to total 40 bicep curls.
