Final answer:
The wings of bats and birds and the streamlined body form of sharks and whales represent examples of convergence in biology.
Step-by-step explanation:
The wings of bats and birds and the streamlined body form of sharks and whales represent examples of convergence. Convergence is when unrelated organisms evolve similar traits or structures due to similar environmental conditions. In this case, bats and birds both evolved wings for flight, while sharks and whales both evolved streamlined bodies for swimming.
