Question

match the vocabulary term to its definition.

1. ______ process by which organisms survive and reproduce
2. ______ body parts similar in structure in different species
3. ______ body parts similar in function but not in structure
4. ______ heritable characteristic that increases fitness

Explanation:

• For question 3: Natural selection is the process by which organisms with favorable traits survive and reproduce more successfully.
• For question 4: Homologous structures are body parts that have a similar structure in different species, indicating a common ancestry.
• For question 5: Analogous structures have similar functions but different structures, which is due to convergent evolution.
• For question 6: An adaptation is a heritable characteristic that enhances an organism's fitness (ability to survive and reproduce).

Answer:

1. d. natural selection
2. b. homologous structures
3. a. analogous structures
4. c. adaptation
