The appendages of this protist will move back and forth like a wagging tail to actively propel the protist forward.

Answer 1

Based on the description of the protist having long lash-like appendages, it sounds like it might have flagella. In such cases, the most likely kind of locomotion is typically associated with flagella, which move in a whip-like or back-and-forth motion. Therefore, the appropriate response would be:

**The appendages of this protist will move back and forth like a wagging tail to actively propel the protist forward.**
