The similarity that you see in bone structure of above animals is a good example of homologous structure because this similarity is caused by existence of a similar structure, but the similarities between the wing of the pelican and wing of the bat is called analogous, because these similarities is caused by similar functions

Explanation:

The forelimbs present in vertebrae such as human, cat, whale and bat have similar structures. This shows that they have a common ancestor. Homologous structures can be described as structures which are similar which shows that they might have arisen from the same ancestor.

Analogous structures can be described as the presence of structures in different organisms which are able to perform similar functions. For example, the wings of a pelican and the wings of a bat.

the relative standard reduction potential of the half-cell in which reduction occurs; more positive than the other half-cell. reduction is a chemical process in which electrons are added to an atom or an ion; it always occurs accompanied by oxidation of the reducing agent.
