Question

6 what is a homologous structure? 7 describe a vestigial organ. 8 what is an analogous structure? body parts that are similar in structure but differ in function body parts that are different in structure but similar in function body parts or organs that are no longer used but may have served a function in the past body parts that are similar in structure and in function

Explanation:

• For question 6: Homologous structures share structural similarity due to common ancestry, even if their functions diverge.
• For question 7: Vestigial organs are remnants of structures that had a function in ancestral organisms but are no longer functional or have reduced function in modern organisms.
• For question 8: Analogous structures evolve independently in different organisms to perform the same function, so they have functional similarity but structural differences.

Answer:

1. Body parts that are similar in structure but differ in function.
2. Body parts or organs that are no longer used but may have served a function in the past.
3. Body parts that are different in structure but similar in function.
