Sudan III is used to detect the presence of lipids.
1. The nervous system allows a free-living flatworm to respond to stimuli in its environment. The eyespots in the nervous system can detect the presence or absence of light and the sensory cell can detect chemicals and movement in water. These adaptions are necessary to the primary environments of flatworms.
Monoclonal antibodies can be used to protect against disease, help diagnose a wide variety of illnesses and detect the presence of drugs or viral and bacterial products. It is these specific traits that make it so valuable.

To detect the presence of CI- ion, add silver nitrate solution. A white opalescence to cloudy precipitate of silver chloride will form and confirm the presence of CI- ion.
The refraction of light by the cornea and lens of the eye makes it possible for an image to form on the retina. Without the formation of an image, it would be possible for the retina to detect the presence or absence of light, but not shapes or objects.
