4 0

Answer:

The correct answer will be option A.

Explanation:

The electrical impulses are generated in the sino-atrial node or SA node, a mass of cells which generates impulse in the upper atrium.  

This electrical impulse transmits from the sino-atrial node to the atrio-ventricular node in the lower portion of the upper atrium through the internodal pathway- the pathway composed of atrial cells.

Once the impulse reaches the AV node, it is transferred to the ventricular portion of the heart through Bundle of His presence in the ventricular septum. This bundle of his divides into left and right ventricles through bundle branches and stimulates both the ventricles.

Thus, option-A is the correct answer.

Lelechka [254]
The answer to your question would be B) Ground water will increase, and here is why: Since the snow piled up on top on the mountain, when Spring comes around, naturally temperature will rise. Once this happens, the snow will melt and run-off of the mountain. Then, since there is so much water, there will be a large amount of ground water, probably more than normal. I hope this helped you a bit!
