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.
I think this is a good plan. In this way, it would stop flooding in the future. Trees help absorb water with their roots. It can absorb at least 20% of the flood water.
However, there are also factors that would affect the trees from growing healthily. Some of the trees would not receive the right amount of energy and sediments can possibly be mix with the good soil.
It is best that we examine why the flooding occurred. There could be other possible reasons for flooding. It can be pollution caused by people throwing their garbages anywhere.
