ASAP! Please? Since monotremes can lay eggs, why aren't they classified as birds?
-- Explanation NOT multiple choice question --

They aren't classified as birds because monotremes are mammals, unlike birds. They are referred to as mammals because they have mammary glands responsible for manufacturing and producing milk. Birds cannot do this.

do you have a picture?

the membrane forms the outside of the cell

cytoplasm is the liquid within

ribosomes are the components within that distribute rna

the dna is the genetic make-up
