Explanation:
The bones in the forelimbs of penguins and seals are best described as analogous, while the flippers of penguins and seals are homologous.
Analogous structures are structures that are similar in different organisms, even though they are unrelated to each other. For instance, the wings of birds and the fins of a penguin or a fish.
Homologous structures are similar structures in related organisms. Both the penguins and the seals have flippers. Another example is the human arm and the wings of a bat. Both have similar structures internally, but while a human lifts items with their hands, the birds use theirs for flying.
