Question

Which is the class of phylum Chordata to which bat belongs?
A. Mammalia
B. Chiroptera
C. Prototheria
D. Aves

Answer 1

Hint:Bat flies but because of the characteristic trait only provided by mammals. They have organs that help feed your babies. The best known of all the species are members of this Phylum, our own. Chordate is simply synonymous with animals in the minds of certain individuals.

Complete answer:The phylum Chordata includes all species that at some point of development have a dorsal notochord known as the backbone. Mammalia is a group of vertebrate animals feeding their young on mammalian gland-produced milk. Bats are the only aerial species.
Bats are put in a phylum Mammalia because they are produced from the milk-secreting glands that are only present in mammalians called mammalian glands. A variety of other reasons for which bats are placed in mammalian groups are:- they are able to give birth to living young men and so are called living creatures, while birds are egg-laying on hatches (processing). bats are oviparous. - The young survive by sucking from nipples the milk secreted from the mammalian gland. The bat mammary glands are present in the chest region and they are the exocrine gland (which is, they have ducts to carry their secretions) which produces milk required to feed neonates (newly created). They are warm blood-free animals, that is to say, they have the capacity to regulate the body's temperature known as homeostasis.

Therefore, choice A is the correct answer.

Note: Since the birds have feathers and wings, however, they can't be called a bird and they cannot be classified in the Phylum Aves because certain characteristics are of the division of Mammalia. All characteristics are studied until each organism is divided and then put in the most appropriate sphere.
