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.

Hope this helps.
Answer:
Production of ATP / cellular respiration
Explanation:
The mitochondrion is the powerhouse of the cell. It is responsible for cellular respiration.
Answer:
The right option for blanks is mRNA, amino acids and polypeptide chain (protein).
Reason:
During protein synthesis first of all mRNA formation occurs from DNA template. Then mRNA come out from nucleus into cytoplasm and bind with ribosome, where tRNA come and binds to mRNA codon with the help of anticodons. and add amino acids. In this way a chain of polypeptide is formed.
Answer:
Light travels in straight lines.
Explanation:
Once light has been produced, it will keep travelling in a straight line until it hits something else.
