Question

i can fly through the air. i give birth to well - developed young and feed milk to my young. i sometimes reside in trees. which of the following classifications fit me? correct answer(s) eutherian bird mammal marsupial

Explanation:

• Mammal: Mammals give birth to live young (well - developed in the case of eutherians) and feed them milk. Bats are mammals that can fly through the air and sometimes reside in trees.
• Eutherian: Bats are eutherian mammals. Eutherians are placental mammals where the young are well - developed at birth.

Birds lay eggs, so they do not fit the description of giving birth to well - developed young and feeding milk. Marsupials give birth to relatively underdeveloped young that then develop further in a pouch, which is not in line with the description of "well - developed young" in the question.

Answer:

eutherian, mammal
