Pros: Might someday cure disease, might someday increase crop yeild, might create things that can be of our use.
Cons: Genetic engineering could cause food allergies, have bad side affects, it could kill animals over time.

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.
Clearcutting results in the removal of topsoil and some animal habits, which can prevent the forest from being able to grow again. While it is cheap, the damage to the food chain and surrounding ecosystem can destroy entire regions.
No, a macromolecule is a large organic molecule
