Answer:
Broca's area refers to a motor speech region, which assists in movements needed at the time of the production of speech. When an injury takes place in the frontal parts of the left hemisphere, it can give rise to various kinds of language issues.

The injury to the left hemisphere is known as Broca's aphasia, also known as expressive aphasia.
Wernicke's aphasia also called receptive aphasia, posterior aphasia, or sensory aphasia is a kind of aphasia in which individual encounters with difficulty in understanding spoken and written language.

The stimulus and response when a human increases his/her physical activity
<h3>What is stimulus?</h3>
- A stimulus is a detectable change in the physical or chemical structure of an organism's internal or external environment.
- The ability of an organism or organ to detect external stimuli, so that an appropriate reaction or response can be made, is called sensitivity
When a human increases physical activity, the amount of fuel burned in its cells also increases, which in turn increases the concentration of dissolved CO2 in the blood. The CO2 reacts with water in the blood to make a weak acid, which lowers the pH of the blood.
