Which behavior can both humans and flatworms do? a. communicate verbally b. see the shape of an approaching predator c. form images from sensory signals d. smell fresh food

The answer to the question is (C) form images from sensory signals.

Flatworms are model organisms for studying the regeneration, development of the eye and the nervous system that processes the sensory inputs. Flatworms have primordial eye present on their head as two tiny eye spots. These eyes can sense changes in the wavelength and intensity of the light. The eye spots are connected to the simple brain through sensory neurons. The brain helps in the formation of a blurred image of the surroundings by processing the input from the two tiny eye spots. This behaviour/ function is common to both the humans and the flatworms.
