Question

6/19
organs that are reduced in size and show no apparent function are
homologous
vestigial
analogous

Explanation:

To solve this, we analyze the definitions:

• Homologous organs have similar structures but may have different functions (e.g., human arm and bat wing), so not matching the description.
• Vestigial organs are reduced in size and have no apparent function (e.g., human appendix), which matches the question.
• Analogous organs have similar functions but different structures (e.g., bird wing and insect wing), so not matching.

Answer:

B. vestigial
