Answer:
A fruit fly, internally infected by a potentially pathogenic fungus, is protected by its antimicrobial peptides
Step-by-step explanation:
fruit fly is protected against certain fungi, Gram-negative bacteria and parasites via epithelial barriers. Various cytotoxic proteins and antimicrobial peptides are synthesized by the fat body in response to infection, and secreted into the blood. Most of them can also be induced in surface epithelia in a tissue-specific manner. An antimicrobial agent called Defensin kills tumor cells and shrinks tumor size in fruit flies.
Fruit fly explained
Fruit fly: any two-winged insect of either the family Trypetidae or the family Drosophilidae (order Diptera). fruit flies are similar to larger flies. They have three body parts: the head, thorax and abdomen. They are generally yellowish in color with several black bands across the abdomen and have wings that are banded or spotted with brown. They are attracted to fruit peelings and are common in fruit producing areas, where they feed and reproduce on overripe or decaying fruit.
