Question
Flipper of a whale and wing of a bat have the similarI. basic functionII. external morphologyIII. pattern of bone arrangementA. I only.B. III only.C. I and II.D. II and II
Solution
The correct answer is B. III only.
Explanation:
I. Basic function: The basic function of a whale's flipper and a bat's wing are not similar. A whale's flipper is used for swimming and maneuvering underwater, while a bat's wing is used for flying.
II. External Morphology: The external morphology of a whale's flipper and a bat's wing are also not similar. A whale's flipper is broad and flat, while a bat's wing is thin and membranous.
III. Pattern of bone arrangement: The pattern of bone arrangement in a whale's flipper and a bat's wing are similar. Both have a similar structure of one long bone (humerus) followed by two smaller bones (radius and ulna), followed by a series of even smaller bones (the digits). This is a result of both animals being mammals and having a common ancestor. This is an example of homologous structures in evolutionary biology.
