Which of the following pathways does NOT directly deliver materials to lysosomes? A. Exocytosis B. Phagocytosis C. Autophagy D.

Use the drop-down menus to decide if an example of similar traits is likely a homologous structure or an analogous structure.
snow_tiger [21]

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.
