In Biology, homologous structures are defined as structures which serve the same purposes because they evolved from the same source (divergent evolution), the opposite of analogous structures, which serve the same purpose but evolved through convergent evolution. Birds' wings and bats' wings are both homologous and analogous. As wings, the two are analogous, but as forelimbs, the two are homologous.
A bird's wing bone
The wing of a bat. The leg of a horse...
The legs of a cat and fins of a whale are analogous structures because they have different evolutionary origins but serve a similar function in terms of movement. Homologous structures would be when two species share a common ancestor and have similar structures with different functions.
There are a few different similarities between the wing of a butterfly and the wing of a bat. Both are used to fly for example.

The sternocleidomastoid in the human is homologous to the sternomastoid muscle of the cat.
A bird without wing
Homologous structures are the same body parts found in different species that look different and do different things that are also made of the same thing ex. the human forearm and the wing of a bird are composed of the same bones however have a completely different appearance and function.

a homogulous series is a series of hydrocabrons which have the same type of bonds. i.e. are grouped by either single, double, or triple bonds, and thus follow a generic formula for how many Hydrogens to a number of carbons
Yes, the nails of a man and claw of a cat are homologous organs with similar structure but performs functions differently.
