Worked Solution & Example Answer:A scientist investigated the nature of the sexual attraction between male and female moths - VCE - SSCE Biology - Question 13 - 2009 - Paper 1
Step 1
female of the moth species produces a chemical that causes an electrical response in the air.
Answer
The experiment shows that when air containing chemicals from female moths was blown over the antenna connected to electrodes, there was a measurable electrical response. This indicates that the female moths produce specific chemicals that elicit a reaction in the male moth's antenna. Therefore, option B aligns best with the observed phenomenon.
