 Chauvet Cave Horses The expression of “cave painting” usually refers to drawing‚ stencil art and painting on the walls and ceilings of prehistoric caves of the Stone Age. Evidence indicates it began during the Aurignacian period (around 30‚000 BC) but reached a highpoint during the late Magdalenian period. The most spectacular examples of this rock art have been discovered in France and Spain‚ where archeologists have found some 350 caves containing Paleolithic artworks‚ but

Samples (Potato‚ Banana‚ Apple) Enzymatic Browning: Enzymatic browning (oxidative) is a reaction between oxygen and a phenolic substrate catalyzed by polyphenol oxidase result in orthoquinone‚ which in turn rapidly polymerized to form brown pigments or melanin. This is the common browning that occur in cut fruits and vegetables [pic] Phenolase enzymes that have been isolated from food sources are oligomers and contain one copper prosthetic group per subunits.

would have only released slightly more betalain‚ as the molecules would have only had a very small amount more heat energy to convert into kinetic energy. Secondly I when I washed each of the beetroot pieces I may not have removed all of the red pigment on the outside‚ so this would have affected my results very slightly. Again this would only have had a small effect on my results‚ because a very slight increase in betalain molecules would not have changed the reading on the

would become stained due to its leakage of betalin (the redish-purple pigment). Betalin is found in the vacuole of beetroot cell. The leakage may have been caused by something happening in the cell membrane of the beetroot – concerning the proteins embedded in the phospholipid layer. The study will require the experiment of different temperatures of water and to find out which in temperature causes the most leakage of the pigment and why it does this. Introduction The study can contribute to biology

palettes that were composed of the usual pigments of his time‚ such as cobalt blue‚ emerald green and vermilion‚ Seurat rendered his subject by placing tiny‚ accurate brushstrokes of different colors close to one another so that they blend at a distance —a process that would not be completed until the spring of 1886. Art critics eventually named this technique Divisionism‚ or Pointillism. But unfortunately its colors have changed. Seurat used this new pigment in his painting‚ a zinc chromate yellow
