Biological pigment

It is astonishing to me that people believe that the pigment of one’s hair could be a determinant of intelligence. However unsupported it may be, some stereotypes of a blonde are ditsy, oblivious, and unintelligent. An example showing the traits that accompany the label is in the movie White Chicks. The film…

minority. In Comparative politics, there are three types of ethnic conflict theories. They are Primordia list accounts, this form of ethnic group and nationalists exist because of traditions of belief and action toward the human features such as biological features pigmentation because of territorial locations. Primordial rely on strong ties to kinship or other members of the ethnic groups and makes it possible to rely on family resemblances and repeated conflicts on its group. The second theory…

Paper Chromatography Paper Chromatography is an analytical method that is used to separate coloured chemicals substances, especially pigments. This is how paper chromatography is conducted: Materials Chromatography Paper (Can also be Coffee Filter) Large Beaker (max one litre) Paper Clips/Sellotape & Skewer Stick Water soluble black marker Water Procedure: Draw a ink dot with the marker on each one of the chromatography paper near the bottom end of the paper. Then stick or paper clip the…

As a bio-psycho-socio-cultural-spiritual being, a generally describe myself in many different aspects in which others may be opposed to believe. Bio-psycho-socio-cultural-spiritual is broken down into five theories: biological, psychological, sociological, cultural, and spiritual. With these theories in mind, being a 21 year old black African American woman growing up in slums of Milwaukee, was not one of the easiest milestone to get though. Everywhere I turn other look down upon me as if I was…

Membrane Self-Assembly Processes: Steps Toward the First Cellular Life by Pierre-Alain Monnard & David W. Deamer Summary: To summarize, early cells must have had a membrane to encapsulate its components and keep them within the cell. This membrane was made up of amphiphiles. This membrane was very permeable and as a result, passive diffusion occurred. Later on this membrane evolved to be a little impermeable as to keep the metabolic reactions and catalysts that drive these reactions within…

A stem cell is simply a cell capable of developing into any other type of cell. It is a biological foundation that hasn’t specialized itself for a specific purpose, however can easily do so for different functions within the body. The cell can be totipotent (able to develop into an organism), pluripotent (able to form tissues of an organism)or multipotent specialized for a certain tissues e.g. blood). Whilst stem cells are mainly known for coming from embryos, there are a wide variety of other…

MS is now in very common use in analytical laboratories that study physical, chemical, or biological properties of a great variety of compounds (Anon., n.d.). For example, protein characterization which helps characterized and sequence proteins. 3.1 Infrared Spectroscopy Infrared (IR) spectroscopy deals with the infrared region of the electromagnetic…

Organic Acids An organic acid is an organic compound with acidic properties. The most common organic acids are the carboxylic acids, whose acidity is associated with their carboxyl group –COOH. Sulfonic acids, containing the group –SO2OH, are relatively stronger acids. Alcohols, with –OH, can act as acids but they are usually very weak. In general, organic acids are weak acids and do not dissociate completely in water, whereas the strong mineral acids do. Lower molecular mass organic acids such…

the surrounding tissue. Difference between Lasers and IPLs The bright radiation, emitted by laser, is monochromatic and penetrates only at a specific depth. It is restricted to that small range depth. IPL however has a broad spectrum that produces biological effects at various depths of the skin that is radiated by different lengths of wave. Therefore, the IPL is a procedure able to treat various beauty blemishes and diseases. Other vital features to enhance its exceptional versatility are: …
