Answer:
Evolution is a gradual change in the inherited traits of a population over many generations. Natural selection is a mechanism where the members of a population best suited to their environment have the best chance of surviving to pass on their genes.
Answer:
- Bird wings and dragonfly wings are both used for flight: Analogous structure
- Clams and snails both have similar muscle structure even though the muscles do different jobs: Homologous structure
- Human and giraffe necks both have 7 vertebrae because we are related: Homologous structure
- The flaps of a Venus flytrap have a similar makeup to oak leaves: Homologous structure
Explanation:
Analogous structures are similar structures that have the same or similar functions in unrelated organisms. Analogous structures aren't the result of evolutionary relationships among organisms (i.e., they were not inherited from a common ancestor). On the other hand, homologous structures are structures inherited from a common ancestor. Homologous structures may or may not have an identical function, but they are the result of evolutionary relationships among organisms and, therefore, they are genetically related.
The correct answer for this question would be the last option. The statement that best describes the reproductive life cycles of ferns and angiosperms is this: <span>The dominant sporophyte phase in the life cycles of both ferns and angiosperms includes the formation of leaves, roots, and stems. Hope this helps.</span>
