Explanation:

1. Locomotion: The Dileptus moves using its cilia and long proboscis, demonstrating self-directed movement, a key living trait.
2. Feeding Behavior: It uses its proboscis to capture and consume smaller organisms, showing energy acquisition (nutrition), a characteristic of life.
3. Cellular Structure: It is a single, complex eukaryotic cell with visible internal organelles, fitting the basic unit of life.
4. Response to Stimuli: The organism avoids obstacles and reacts to the presence of prey, indicating irritability/response to environment.

Answer:

1. Self-directed locomotion using cilia/proboscis
2. Active feeding on smaller organisms
3. Visible complex single-cellular (eukaryotic) structure
4. Responsive movement to environmental stimuli (obstacles/prey)
