Answer 1

Answer:

B and E

Explanation:

The correct answer would be that both birds and mammals are vertebrates and are also endothermic.

Both birds and mammals belong to the same animal kingdom. They also belong to the same chordate phylum but belongs to different classes under the phylum. However, they both belong to the same sub-phylum Vertebrata - a group of chordates with the vertebral column.

Birds (aves) and mammals represent different classes of animals. Birds lay eggs that later hatch when conditions are right to give rise to their young ones. Mammals, on the other hand, give birth to their younger ones and are able to produce milk through their mammary gland to feed them. The body of mammals is characterized by the presence of hairs that help insulate the body making them to be homoiothermic, unlike birds that of birds, where hair is replaced with feathers.

However, both birds and mammals are endothermic, that is, they both maintain a fairly constant body temperature irrespective of the temperature of their environment.

The correct options are B and E.
