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.

Endoplasmic reticulum serves as transpiration area. The correct option is B.

<h3>What is endoplasmic reticulum?</h3>

The endoplasmic reticulum (ER) is a large, dynamic structure in the cell that performs numerous functions such as calcium storage, protein synthesis, and lipid metabolism.

The ER's various functions are carried out by distinct domains, which include tubules, sheets, and the nuclear envelope.

The endoplasmic reticulum can be smooth or rough, and its function is generally to produce proteins that allow the rest of the cell to function.

Ribosomes, which are small, round organelles that make proteins, are found in the rough endoplasmic reticulum.

Thus, the correct option is B.

kirill [66]

The biodiversity will decrease due to an increase in pollution is the effect will have on the biodiversity on the river ecosystem.

Option A

<u>Explanation:</u>

Biodiversity is the actual collection of total amounts of flora and fauna present in a particular ecosystem. The river ecosystem consists of the aquatic plants, the aquatic animals like fishes,etc and even the surrounding land plants and animals, who utilize the river water for their living.

The inclusion of the polluted sewage of the surrounding area into the river directly mixes several chemicals to the water, which are potentially harmful for all the animals living there. This leads to destruction of the flora and fauna of both water and lands surrounding them. This hampers the biodiversity of the water as well as surrounding land.
