Animal kingdom

Questions:

1.In order to eradicate mosquitoes Housing colony members were asked to keep the surroundings dry, not to let water standing any where and cover the drainage. It was found that the strategy worked and there was decline in the number of mosquitoes. What according to you is the reason for the decline in the number of mosquitoes.?

Ans1: Mosquito belongs to class Insect, phylum Arthropoda . Its development is indirect with distinct stages like egg, larva, pupa and adult. It breeds in water and so if water is not provided it cannot complete its life cycle . This leads to the decline in the number of mosquitoes.

2. Ravi’s younger brother of class III stated that bats are like birds as they are able to fly. How will you contradict him and make him understand that bats are mammals and not birds. 

Ans2: Bats have external ears, body covered with hairs and mammary glands. They have skin instead of feathers and mouth with teeth instead of beak. They do not lay eggs but give birth to young ones.
