Which of the following are common vectors that transmit diseases?

Chemicals
Mosquitoes
Salmonella
Roaches

The correct answer is: Mosquitoes

Mosquitoes are indeed common vectors that transmit diseases, making this the correct choice. They are well-known for spreading various infectious diseases such as malaria, dengue fever, Zika virus, and West Nile virus. Vectors are organisms that carry and transmit pathogens to humans or other animals, and mosquitoes are particularly effective at this due to their ability to bite and draw blood from hosts, facilitating the transmission of disease-causing organisms. In contrast, chemicals, while they may relate to the spread of certain illnesses through contamination (like pesticides causing poisoning), do not actively transmit diseases. Salmonella refers to a type of bacteria that causes foodborne illness and not a vector itself, as it does not carry diseases from one host to another. Roaches can carry pathogens that may contaminate food and surfaces but are not classified as primary vectors for diseases in the same way that mosquitoes are. Their role is more about being a contaminator rather than a direct transmitter of specific diseases through a biological process.
