Answer:

This question is incomplete as it lacks options, the options are:

A) What is the radius of each particle of the substance?

B) Does the substance contain more than one type of atom?

C) Was a chemical reaction necessary to create the substance?

D) What is the electrical charge of the particles of the substance?

The answer is B

Explanation:

In chemistry, an element is a substance made up of a single type of atom i.e. only one atom of the same type constitutes an element while a compound is a substance that contains two or more different elements. If a compound contains different elements, it means that a compound will certainly contain more than one type of atom.

According to this question, the best question to ask when Alyssa wants to differentiate between an element and a compound is: DOES THE SUBSTANCE CONTAIN MORE THAN ONE TYPE OF ATOM?

- If the answer is yes, the substance is a COMPOUND

- If the answer is no, the substance is an ELEMENT.

PLEASE ANSWER URGENTLY!!

dlinn [17]

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.
