Question

protozoan organelles can be highly specialized into structure analogous to
○ mouths
○ digestive systems
○ reproductive tracts
○ legs
○ all of the above

Explanation:

Protozoans are single - celled organisms. Their organelles can be specialized to perform functions similar to the organs or structures of multicellular organisms. Some protozoan organelles can act like mouths (for ingestion), some like digestive systems (for digestion), some like reproductive tracts (for reproduction), and some like legs (for movement, e.g., cilia or flagella can be analogous to legs for locomotion). So protozoan organelles can be specialized into structures analogous to all of the options given.

Answer:

E. all of the above
