The correct answer is adding ninhydrin to developing solvent.

Ninhydrinis used to detect (color) amino-acids, since amino acids are colourless compounds. So, after development, the TLC plate is sprayed with ninhydrin reagent and dried in an oven, at 105°C for about 5 minutes. It reacts with α- amino acids that results in purple coloured spots.

Which of the following organisms exhibits cephalization?
bezimeni [28]
Cephalization describes the process by which organisms develop a distinct head. The head of a cephalized organism contains a concentrated group of nerves, or brain, that controls the rest of the organism, as well as specialized organs for consumption and perception, like mouths, eyes and ears. Cephalized organisms exhibit a distinct division between parts of the body; they have a front, back, top and bottom. These animals comprise the bulk of animals that are encountered on a daily basis.
