jenyasd209 [6]

Answer:

conditioned stimulus; conditioned response

Explanation:

In respondent conditioning, also known as classical conditioning, a natural potent stimulus (food)  that elicits a response naturally is paired with a neutral stimulus (bell), which initially would not produce any response but only attract attention. Learning or new behavior is elicited in this way.

The previously neutral stimulus which now elicits salivation is referred to as conditioned stimulus, while the salivation is called the conditioned response.

Fofino [41]

You would predict this to occur as an opening of atrioventricular valves, atria contraction, and filling of ventricles with blood if an action potential could not be received by the atrioventricular node, despite the propagation through the sinoatrial node.

So, the correct options are B, C &E.

It enables a left atrium action potential, causing both atria to contract simultaneously before the ventricles do. The AV delay delays the contraction of the ventricles by slowing the rate at which the impulse reaches them. This is significant because it gives the atria enough time to finish contracting so that the greatest amount of blood may be discharged into the ventricles.

The right and left atria to have time to contract first (eject blood to the ventricles) before the ventricles contract, which is why the AV node delay is so crucial. The AV node is a modified myocardium.

Answer:

Written below.

Explanation:

5. During meiosis, a reproductive cell and its nucleus divide twice and produce four cells––two pairs of identical haploid cells.

6. Homologous chromosomes are two pieces of DNA within a diploid organism that carry the same genes, one from each parental source. In simpler terms, both of your parents provide a complete genome. Each parent provides the same 23 chromosomes, which encode the same genes.
