Which of the following structures in a housefly aids in the transmission of diseases in man?
Answer Details
The structure in a housefly that aids in the transmission of diseases to humans is its hairs.
Houseflies are known to carry various disease-causing microorganisms such as bacteria, viruses, and parasites on their body parts, including their hairs. These microorganisms can be picked up by the housefly when it feeds on contaminated materials such as feces, garbage, or decaying matter, and can then be transferred to humans when the housefly lands on food or surfaces that humans come into contact with.
Housefly hairs are particularly effective in transmitting diseases because they can trap and hold onto small particles, including microorganisms. The hairs on their legs and body can easily pick up and transfer these microorganisms to new surfaces or onto human skin when they land on them.
Therefore, it is important to keep houseflies away from food and living areas to reduce the risk of disease transmission. This can be done by practicing good sanitation, keeping food covered, and using fly traps or insecticides.
