how are parts of birds & fish similar in structure & function
That depends on what two species you're referring to. Homologous parts are similar in structure and evolutionary origin, though not necessarily in function. for example: human arms and bat's wings Analogous parts, on the other hand function similarly, but may not be similar in structure or evolutionary origin. example: a butterfly's wings and birds' wings
The body parts similar in origin and structure you're referring to are "homologous" structures. These structures arise from a common ancestor and have similar anatomical features, despite potentially serving different functions in various species. An example is the forelimbs of mammals, which share a similar bone structure but are adapted for different purposes, such as flying in bats and swimming in whales.
Analogous structures are body parts or organs in different species that have a similar function but not necessarily a common evolutionary origin. For example, the wings of birds and bats are analogous structures because they both serve the purpose of flight, even though they evolved independently.
A phospholipid has a charged head and an uncharged tail.
Animals that caw are crows and rooks. They are both birds that looks similar but the rook has a skinnier beak than the crow.

The wings of bats and birds have a similar function of flight but developed differently, with bat wings being elongated fingers covered in a thin membrane while bird wings are modified forelimbs covered in feathers. Additionally, the eyes of cephalopods (e.g. squid) and vertebrates both function in vision, but cephalopod eyes developed independently and have a different structure.
Analogous structures are body parts that have a similar function in different species but have evolved separately, thus not sharing a common ancestor. These structures result from convergent evolution, where organisms adapt to similar environmental pressures.
Homologous structures refer to structures on different species that are similar in function and their evolutionary origin. Analogous structures are similar in function but do not share a similarity in evolutionary origin.

Body parts similar in orgin and structure?
The function of a cow's heart is the same as a human heart - to circulate blood throughout the body. The cow's heart is very similar to a human heart in structure.
The type of structure where body parts share a common function but not a common structure is known as analogous structures. These structures arise through convergent evolution, where different species independently evolve similar traits to adapt to similar environments or challenges. A classic example is the wings of bats and the wings of butterflies; both serve the function of flight but are structurally different.
Structure refers to the physical arrangement of parts or components, while function refers to the role or purpose that those parts or components serve. In many cases, the structure of an object or system is closely related to its function, as the design of the structure often influences how well it can perform its intended function.
