Answer: Skin; Brain, GSA - General Somatic Afferent
Explanation:
<em>Whilst bushwalking, Brian begins to feel chafing sensation in his thighs. In order to perceive this chafing, neural impulses must travel in one direction – from his </em><em><u>skin</u></em><em> to his </em><em><u>brain</u></em><em>. This information would travel via </em><em><u>GSA </u></em><em>neurones.</em>
The peripheral mechanoreceptors which are found on the skin and used to detect movement will detect the chafing and send it to the brain.
This information will be received by the brain through General Somatic Afferent neurons which are spread across the body and have the primary function of detecting touch and temperature.
B. Positive feedback, it decreases body temperature.

In many functions of a living
organism, it cannot make its own energy. It uses energy from its environment, retrieves
and converts into a usable and edible matter. Organisms that can do this
process is the autotrophs, they can facilitate photosynthesis which they gather
energy from the sun, water and carbon dioxide in order to create energy by
then, the transfer of this energy to other organism is played by the food chain
–food web. </span>
