of photosynthesis release oxygen as a byproduct. the reaction of this process: Chlorophillian pigment 6H2O + 12CO2 + S.E -----------------------> C6H12O6+ 6O2 + 6H2O Easily‚ we can explain the reaction like 6 molecules of water plus‚ 12 molecules of Carbon Dioxide plus Sun energy‚ cross with chlorophillian pigment‚ in the product we have glucose‚ plus oxygen‚ plus water. We can put so briefly the process saying that the organisms use the energy from

Art in the Renaissance era was very influential; this period experienced changes in art‚ new forms of artistic entertainment were introduced‚ and new techniques were developing. In Japan‚ a new style of artwork was beginning to blossom and grow in popularity: Ukiyo-e‚ “Pictures of the floating world.” Typical Ukiyo-e portrayed images of the earth and the arts.

Vitiligo Vitiligo is a condition that causes depigmentation of parts of the skin. It occurs when skin pigment cells die or are unable to function. The cause of Vitiligo‚ aside from cases of contact with certain chemicals‚ is unknown‚ but research suggests it may arise from autoimmune‚ genetic‚ oxidative stress‚ neural‚ or viral causes. The incidence worldwide is less than 1%‚ with some populations averaging between 2-3% and as high as 16%. Signs and symptoms The only symptom of Vitiligo is the presence

by the same Mendelian model? Part II – Skin Color is a Polygenic Trait Differences in skin color are largely due to differences in the amount of melanin‚ a dark pigment produced by skin cells. There are different variations of melanin‚ eumelanin and phaeomelanin‚ and many enzymes interact in the formation and movement of skin pigments. In an early model (and it still works; although the underlying sequence of enzymatic activity is much more complex) skin coloration was thought to have been controlled

haem. Through the phagocytic actions of macrophages present in the CSF‚ the haem is initially broken into biliverdin before the iron compounds are removed‚ and through degradation by enzymes‚ the degradation product bilirubin is produced. This pigment is responsible for producing the yellow-brown appearance in positive CSF samples and is detectable at a wavelength of 476 nm. Through oxidation of the haem group‚ methaemoglobin is sometimes produced after around 10 days following the initial erythrocyte

Keratinocytes: The most numerous cells are the keratinocytes which produce keratin‚ a fibrous protein responsible for protective properties of the epidermis. Melanocytes: located at the base of the epidermis. Specialized cells that synthesize the pigment melanin. Melanin protects the cell nucleus from the destructive effects of UV radiation Langerhans cells: arise from the bone marrow and migrate to the epidermis and other areas of the body containing stratified squamous epithelial tissue.
