Mosquito donot have teeth. justify? |
|
Answer» Answer: HEY MATE HERE IS YOUR ANSWER:-Mosquitoes bite, so it MAKES sense that these insects have teeth to bite you with. In the mind of an uninformed person, this would make a lot of sense. HOWEVER, mosquitoes don’t bite with their teeth, so there is no NUMBER of teeth required for them to survive or reproduce. The confusion about this issue all has to do with their little stinger called the ‘proboscis‘. The mosquito teeth myth is LIKELY to come from the fact that the mosquito’s proboscis, with which they bite their unwilling subjects, consists of a large number of sharp EDGES, which resemble human teeth. However, these so-called ‘teeth’ are used to reach the bloodstream of their victims, instead of digesting food. |
