An arm is an analogous feature because it has evolved independently in different species to serve a similar function, like in the wings of birds and bats. It is not homologous, as it does not share a common evolutionary origin, like the forelimbs of vertebrates. An arm is not vestigial, as it is a functional and adaptive trait that has been retained through evolution for various purposes.
A hydrocarbon that possesses one double bond belongs to the next homologous series called alkenes.
Homologous structures in humans include the forelimbs, such as the human arm, the whale's flipper, and the bat's wing. Although these limbs serve different functions—grasping, swimming, and flying, respectively—they share a similar underlying skeletal structure, indicating a common evolutionary ancestor. This similarity in anatomy despite differing functions exemplifies the concept of homology in biology.

Homologous means similar to but not the same thing, as a squirrel's foreleg is homologous to a human's arm.
Yes.
A homologous structure to a human arm bone would be the forelimb bones in other mammals, such as the forelimb bones in a bat or a whale. These structures may have different functions (e.g. for flying or swimming), but they share a common evolutionary origin with the human arm bones.

The sternocleidomastoid in the human is homologous to the sternomastoid muscle of the cat.
A human cell typically contains 23 pairs of homologous chromosomes.
No, a bat wing and a mouse arm are not homologous structures. Homologous structures are similar body parts that are derived from a common ancestor, while bat wings and mouse arms have different evolutionary origins and serve different functions.

Not all animals have the same skeletal structure. Whales have bones in their "flippers" that resemble the same bones that make up the human "arm". This is called a homologous structure.
