Food poisoning involves the effects that decomposed or contaminated food can have on a group of people who eat it, and can cause illness in all or most individuals.

Although patients' symptoms should be treated and preventive education provided, the best course of action for a scientist is to investigate the cause.

The response of a scientist to the increase in food poisoning cases is to determine the type and source of food, as well as the nature of the alteration it has -decomposition, contamination, bacteria- in order to eliminate the source and avoid new cases.

The other options may be valid in the face of the appearance of food poisoning cases, but they are not the best procedure with which a scientist would respond.

It is called THERAPEUTIC INDEX. Therapeutic index is the comparison of the amount of a particular drug that causes the desired therapeutic effects and the amount that causes toxicity. The index can be low or high. A drug with a low therapeutic index will require only a small increase in dose to produce toxic effects in users.

Answer: Skin; Brain, GSA - General Somatic Afferent

Explanation:

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 skin to his brain. This information would travel via GSA neurones.

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.
