Background information: .
A species of moths has wings that are 4cm long and 2 cm wide.
. - A moth was hatched that has a mutation on the gene responsible for the length of the wings. It develops wings that are 1 % cm long,
and 2 cm wide.
Question: Would this mutation be beneficial, neutral, or harmful to the survival of the moth?
O Neutral because they moth still has wings
O Harmful because the moth has a different color wing that it should so it won't be able to find a mate

escape predators
Beneficial because now the moth has better camouflage

Specific immune responses are triggered by antigens. Antigens are usually found on the surface of pathogens and are unique to that particular pathogen. The immune system responds to antigens by producing cells that directly attack the pathogen, or by producing special proteins called antibodies.
