Bouvier‚ Dogbo‚ and Camara studied whether it is possible to produce bixin using the microorganism E.coli. Bixin is a pigment that is only synthesized naturally by the plant Bixa Orellana (from tropical America)‚ and it is the second pigment used in the world‚ for example in cosmetic‚ food‚ and pharmaceutical industries. The authors presumed that engineering genes in sink organs of plants presenting high amounts of lycopene could be an alternative to the natural occurring Bixin‚ which would be advantageous

the data grows smaller. The smaller the graph goes‚ the more pigment it has. In the graph you can see with sixteen pieces of beet it goes just over 90. While the once piece of beet has a really high bar‚ showing it does not have a lot of pigment as compared to the smaller pieces. Interpretation: The bigger pieces let out less red pigment and the smaller pieces let out more red pigment. The smaller pieces let out more red pigment because there is more surface area on the smaller ones. While the

changes with respect to the environments such as temperature (Maynard G. Hale) . In the experiment‚ we use the red beets in order to see how the structure of the membrane relates to its function. Red beets cells contain central vacuoles that house a pigment called Betacyanin. When beet cells remain intact‚ Betacyanin stays within the cell. Once the beet cells are disrupted‚ betacyanin will leak out and create a pink/red color in the environment. An increase in membrane damage will cause more betacyanin

I was the meanest‚ richest and smartest boy in my Primary Four class. Being a notorious bully‚ students cowered at the mere mention of my name. Without any reason‚ I would start bullying other students. I always had a bag of tricks up my sleeves‚ so my ‘attack’ on my ‘victim’ would come unexpectedly. I always had a sense of satisfaction after successfully bullying a student. It was like another feather in my cap. Others’ misery was my happiness. On one typical Monday recess‚ I caught sight of

mummies from Egypt‚ Peru‚ and the Philippines have been radiocarbon dated to 2000 BC. The word tattoo is derived from the Tahitian word ta-tau‚ which means “the result of tapping.” Modern artists use an electrically powered instrument to inject tattoo pigment 50–3‚000 times per minute to a depth of about a sixty-fourth to a sixteenth of an inch into the dermis (Armstrong & Murphy‚ 1997). The instruments use sets of one to 14 vibrating needles (Sperry‚ 1992). Tattoo Procedures and Regulations Tattooing

this reduction reaction ultimately come from water‚ which is then converted to oxygen and protons. Energy for this process is provided by light‚ which is absorbed by pigments. Chlorophylls absorb blue and red light and carotenoids absorb blue-green light but green and yellow light are not effectively absorbed by photosynthetic pigments in plants; therefore‚ light of these colors is either reflected by leaves or passes through the leaves(Arizona 2007). This is why plants are green. A certain colors

For Homo sapiens‚ the way we perceive the world through our power of sight‚ came from the species of primates that existed before us according

Plotting the Absorption Spectrum of Lettuce Leaf Extract November 14‚ 2012 Aim: To see how chlorophyll pigments absorb electromagnetic radiation at different wavelengths‚ with the use of a spectrophotometer to vary the wavelength of incident light‚ and then plot an absorption spectrum. Hypothesis: The chlorophyll pigments of the spinach leaf’s chlorophyll extract will absorb more electromagnetic radiation at wavelengths which correspond to the wavelengths of colors other than green‚ as chlorophyll

spinach pigments‚ and analyzed what colors of light these pigments absorb. By using TLC plate‚ hexane and acetone‚ I separated the pigments of spinach‚ and discovered that the main pigments were green and yellow. This works because with different polarities‚ pigments move at different rates. Hexane and acetone were also used to separate chlorophyll and carotene from spinach. Since they are polar‚ they can separate organic and inorganic things. From the experiment‚ I know that the pigments of spinach
