Everything is made up of matter . Matter can either be a solid (example: gold)‚ a liquid (example: hydrogen) or a gas (example: Hydrogen). Matter can be classified as either a mixture or a pure substance or a mixture. There are two types of mixtures a homogenous mixture and a heterogenous mixture. A homogenous mixture is a mixture that has been thoroughly combined and has been turned into a solution. A heterogenous is a mixture in which the particles has not been thoroughly combined.

of cellular pigment. Albinism is a form of hypopigmentary congenital disorder‚ characterized by a partial hypomelanism or total lack of melanin pigment in the eyes‚ skin‚ and hair. Albinism results from inheritance of recessive alleles. Also another term used for albinism is an albino. Albinism is hereditary; it is not an infectious disease and cannot be transmitted through contact blood transfusions or other rectors. Many types of albinism exist‚ all of which involve lack of pigment in varying degrees

MCOPS‚ Manipal ANALYTICAL METHODS FOR RESIDUAL SOLVENTS INTRODUCTION: Organic solvents are routinely applied during synthesis of drug substances‚ excipients‚ or during drug product formulation. They are not desirable in the final product‚ mainly because of their toxicity‚ their influence on the quality of crystals of the drug substance and their odor or taste‚ which can be unpleasant for patients. To remove them‚ various manufacturing processes or techniques (usually under

the E.coli strain using Ni2+ agarose affinity chromatography technology Abstract The purpose of this experiment was to express and purify the his6-tagged recombinant form of GFP (rGFP) from the organism E.coli using Ni2+ agarose affinity chromatography. The expression of rGFP was confirmed qualitatively using the UV light and was expressed in the E.coli strain BL21 (DE3) (-- removed HTML --) (-- removed HTML --) . Ni2+ agarose affinity chromatography was used to purify the crude extract and different

oleracea and Musa acuminata‚ which use different wavelengths of light to display various pigments of color. The light energy for photosynthesis calls for an array of light to be absorbed by the plants. In this experiment‚ the different wavelengths of light can be traced and graphed by extracting chlorophyll from these two plants and placing them into a spectrophotometer‚ which identifies what wavelengths of light a pigment absorbs. It was found that Musa acuminata‚ commonly referred to as banana palm‚ showed

Vitiligo Vitiligo is a skin condition‚ and sometimes is referred to as the Michael Jackson Disease. It is a skin condition in which there is a loss of pigment from areas of skin. That then results in irregular white patches of skin. Vitiligo occurs when the melanin forming cells‚ also called melanocytes fail to produce melanin. Melanin is the dark pigment that is in the epidermis that gives us our skin color. When the melanocytes fail to produce melanin‚ white patches of skin appear on the skin. Although

Hypothesis Organic solvent and high temperature will destroy the cell membrane and make it permeable to the red pigment. The higher the concentration of the alcohol‚ the greater will be this effect. Principle Beetroot is the material used in this experiment to demonstrate the effects of high temperature and chemicals on the permeability of the cell membranes. Beetroot contains a red pigment called betalain‚ which is located in the large central vacuole of the beetroot cells. The vacuole is enclosed
