Which supports the idea that birds and butterflies both have wings but they do not have a common ancestor with wings?
The wings are analogous structures that evolved differently and do not have a similar internal structure.
The wings are homologous structures that evolved differently and do not have a similar internal structure.
Wings of birds are vestigial structures, but the wing structures of bats are not vestigial.
Wings of bats are vestigial structures, but the wing structures of birds are not vestigial.

The wings are analogous structures that evolved differently and do not have a similar internal structure.

Explanation:

The wings have the same function, but birds and butterflies evolved in different ways, so the internal structures are not the same.

the answer will be a) proteins i believe

if, i suppose that a bee stings me swinging my hand away from a bee. then that if, i persist patient when a bee or wasp areas on your surface to investigate a scent or to take h2o and i secreting heavily, the bug ultimately will move of its personal agreement. if i don't need to set for it to disappear, lightly and gently wipe it off with a part of the paper.
