Why you will spray ninhydrin for analysis in chromatography?
Since amino acids are colourless compounds, ninhydrin is used for detecting them. To identify this, after development, the TLC plate is sprayed with ninhydrin reagent and dried in an oven, at 105°C for about 5 minutes. Ninhydrin reacts with α- amino acids that results in purple coloured spots [(due to the formation of the complex - Rheuman's purple).

Why you are adding marble chips during heating?
Marble chips are added during heating so that the solution or substance can boil evenly. Evenly boiling the solution will cause it not to have heating spots, which can cause an eruption of bubbles. Heating spots are caused when the heat being applied is only getting to the liquid at the bottom of the flask, causing the liquid down there to evaporate more quickly than the upper liquid. The liquid evaporating causes bubbles to shoot through the solution vigorously, disrupting the system. To avoid these heating spots, we add marble chips or boiling chips to induce a nice, even boil.

Why do American bulldogs develop black spots on their skin?
I have always heard that American Bulldogs inherited their black spots because of the breeding from Dalmations and certain hunting retrievers such as the English Pointer. Mostly the white dogs are the ones with the spots and as they get older the hair actually grows darker i nthose spots. My AMBD was white as a puppy and as he matued he developed brown freckles where the black spots were on his back. Of course he was covered with black spots but only developed the brown spots on his back. Hope this helps.
