The Broca's area is located in the lobe:

Correct Answer: A

Rationale: Frontal lobe is the correct answer because Broca's area, which is responsible for speech production and language processing, is located in the posterior part of the frontal lobe, typically in the left hemisphere. Damage to this area results in Broca's aphasia, characterized by non-fluent speech and difficulty forming sentences.

Correct Answer: B

Rationale: The action potential is initiated by the influx of Na+ through voltage-gated sodium channels, causing depolarization. It is terminated by the efflux of K+ through voltage-gated potassium channels, leading to repolarization. The action potential does not decline in amplitude as it propagates along the axon (all-or-none principle), and there is a net movement of Na+ and K+ across the membrane during the process.
