Answer 2

Explanation:

• When mosquitoes bite, they spit saliva and viruses on the surface of the skin.
• Saliva causes inflammation and prevents the clotting of blood from that particular area, which facilitates the sucking of blood by mosquitoes.
• Viruses can easily penetrate through this inflamed site and from that site they multiply and infect the whole body.
• Such microorganisms and viruses which are spread by mosquitoes:
