Hair structure,😯😯

Image
The hair is made up of 95% keratin, a fibrous, helicoidal protein (shaped like a helix) that forms part of the skin and all its appendages (body hair, nails, etc.). Keratin is synthesized by keratinocytes and is insoluble in water, thus ensuring impermeability and protection for the hair. Some 18 amino acids can be found in the hair, such as proline, threonine, leucine and arginine. Keratin is particularly rich in cysteine (a type of sulfurated amino acid), which forms disulfide bonds between molecules, adding rigidity and resistance to the entire structure The hair’s structure can be divided into 3 distinct parts: - Medulla: innermost layer of the hair shaft, composed of an amorphous, soft, oily substance - Cuticle: thin protective outer layer that contains the nourishing portion essential to hair growth. It is highly keratinized, composed of cells shaped like scales that are layered one over the other, measuring about 60 micrometers long and about 6 ...

Panibharatha's parents pressured him to become a doctor,[15] so he was transferred to the Thibbotuwawe Gunananda Thero, who lived in Ratnapura, to practice medicine.[2] While Panibharatha studied medicine, he continued to practice dancing.[16] In 1937, J. D. A Perera invited him to work as a drummer for Perera's wife, Chandralekha, in Colombo.[5][8] In 1940, Panibharatha dressed as a traditional Ves Dancer at the Attanagalle Rajamaha Vihara for his traditional inauguration into dancing.[14] After seeing his excellence in drumming and dancing, J. D. A Perera allowed Panibharatha to attend his school, Lawrence College, as a student.[2] He was also permitted to work as a dance teacher while studying at the school.[7] Later, he entered the Vidyalankara Pirivena to learn the Sanskrit language and literature from Rambukwella Sri Siddhartha Thero.[5] In 1938, at the age of 18, he was appointed as the dance teacher at Nalanda College, Colombo.[8][17] After working as a teacher for se...

🍫🍫Chocolate 🍫🍫🍫

Image
The seeds of the cacao tree have an intense bitter taste and must be fermented to develop the flavor. After fermentation, the beans are dried, cleaned, and roasted. The shell is removed to produce cocoa nibs, which are then ground to cocoa mass, unadulterated chocolate in rough form. Once the cocoa mass is liquefied by heating, it is called chocolate liquor. The liquor may also be cooled and processed into its two components: cocoa solids and cocoa butter. Baking chocolate, also called bitter chocolate, contains cocoa solids and cocoa butter in varying proportions, without any added sugar. Powdered baking cocoa, which contains more fiber than cocoa butter, can be processed with alkali to produce dutch cocoa. Much of the chocolate consumed today is in the form of sweet chocolate, a combination of cocoa solids, cocoa butter or added vegetable oils, and sugar. Milk chocolate is sweet chocolate that additionally contains milk powder or condensed milk. White chocolate contains cocoa butter,...

🏜️🏜️ desert 🏜️🏜️🏜️

Image
Deserts are formed by weathering processes as large variations in temperature between day and night put strains on the rocks, which consequently break in pieces. Although rain seldom occurs in deserts, there are occasional downpours that can result in flash floods. Rain falling on hot rocks can cause them to shatter, and the resulting fragments and rubble strewn over the desert floor are further eroded by the wind. This picks up particles of sand and dust, which can remain airborne for extended periods – sometimes causing the formation of sand storms or dust storms. Wind-blown sand grains striking any solid object in their path can abrade the surface. Rocks are smoothed down, and the wind sorts sand into uniform deposits. The grains end up as level sheets of sand or are piled high in billowing sand dunes. Other deserts are flat, stony plains where all the fine material has been blown away and the surface consists of a mosaic of smooth stones. These areas are known as desert pavements, ...
