Information of Michael King’s lab sheet can state two conclusions. The first conclusion that can be stated from information of the lab is water seeped through some of the oil. The density of the water was 1.1 g/mL and the soap was 1.446 g/mL‚ the soap was clearly denser than water. For proof that the water seeped through the soap Michael King’s observation sheet of water stated: “The water is leaking down into the soap‚ but still sits on top of the dish soap.” Later through his observations it elaborates

practical is to investigate the effects of different treatments on photosynthetic electron transport by using isolated chloroplasts from silverbeet leaves. As photosynthesis proceeds‚ any electrons produced will reduce the dye DCPIP to its colourless form‚ so a rapid decrease in dye colour will indicate a rapid rate of photosynthetic electron transport. Given this‚ I predict that placing the reaction in the dark will produce no change in colour as well as the treatment of adding DCMU‚ as it is an inhibitor

as weddings‚ festivals or even births. Here‚ in the United States people often use it as tattoos. Since henna is not permanent‚ some get it to see how it will turn out before getting the actual tattoo. Another way to use henna is using it as a hair dye. It prevents breakage‚ it reduces dandruff‚ hair is thicker‚ it promotes growth because it has antibacterial and antifungal properties‚ and it also smooth’s the hair cuticle‚ giving hair healthy appearance. Henna is safe at any age and is mostly used

will be a change in the rate of colour leakage. Scientific Background Beetroot is a very familiar vegetable and is commonly known as beet. It is famous in most recipe books that advice that its outer skin is not to be removed to avoid getting red dye in the cooking water. If we look at the internal structure of beetroot‚ it will be observed that it consists of cells which are surrounded by a cell membrane. This cell membrane structure separates the contents of the cell from outside. The membrane

(C18H14N2O8S2) and bleach. C18H14N2O8S2 (aq) + NaOCl (aq) → products Allura Red is a food dye‚ which is an organic molecule with alternating single and double bonds. The color of the dye comes from the delocalization of electrons in the πbonding system (Exton‚ 149). Bleach is an aqueous solution that contains sodium hypochlorite (NaOCl). The hypochlorite of bleach breaks the double bonds of the food dye through oxidation‚ forming molecules that do not absorb visible light and thus bleaching the product
