Taste buds contain the receptors for taste. They are located around the small structures on the upper surface of the tongue, soft palate, upper esophagus and epiglottis, which are called papillae.These structures are involved in detecting the five (known) elements of taste perception: salty, sour, bitter, sweet, and umami. Small openings in the tongue epithelium, called taste pores, parts of the food dissolved in saliva come into contact with taste receptors. These are located on top of the taste receptor cells that constitute the taste buds. The taste receptor cells send information detected by clusters of various receptors and ion channels to the gustatory areas of the brain via the seventh, ninth and tenth cranial nerves.On average, the human tongue has 2,000–8,000 taste buds. The majority of taste buds on the tongue sit on raised protrusions of the tongue surface called papillae. There are four types of papillae present in the human tongue: Fungiform papillae - as the name s...

Deoxyribonucleic acid ( DNA ) is a molecule that encodes the genetic instructions used in the development and functioning of all known living organisms and many viruses. Along with RNA(base form of a protein) , DNA is one of the three major macromolecules essential for all known forms of life. Genetic information is encoded in DNA. DNA molecules are double helix, consisting of two long polymers of simple units called nucleotides, molecules with backbones made of alternating sugars (deoxyribose) and phosphate groups (related to phosphoric acid), with the nucleobases (G, A, T, C) attached to the sugars. DNA is well-suited for biological information storage, since the DNA backbone is resistant to cleavage and the double-stranded structure provides the molecule with a built-in duplicate of the encoded information. The DNA's structure is important to know. Its nucleotides contain the nitrogenous bases called G,A,T,C. These link in a pattern. Guanine and Cytosine link together and Aden...

A motion sickness occurs when you travel in a car and see a stationary thing or a reead a book you feel vomiting. This happens because your vestibular system in your ear is vibrated by the motin of the car and your eyes are seeing something stationary. So your brain can't take this and produces nuerotoxin which caint be in your body so you throw it out which you call vomiting.

Magnetite is a mineral, one of the two common naturally occurring iron oxides (chemical formula Fe 3 O 4 ) and a member of the spinel group. Magnetite is the most magnetic of all the naturally occurring minerals on Earth. Naturally magnetized pieces of magnetite, called lodestone, will attract small pieces of iron, and this was how ancient people first noticed the property of magnetism. Small grains of magnetite occur in almost all igneous and metamorphic rocks. It is black or brownish-black with a metallic luster. Lodestones were used as an early form of magnetic compass. 

Do you know that light actually pushes you about a square inch were you weigh about a billionth of a killogram which is about 0.000000001 its seems very less but in a big city like Chicago in a sunny day it wieghs about 140 kilograms. Also that light travels about 299,792458 m/s in the vacumm and it travels 298,925,574 m/s in the air.

Acancer cell is produced in your body when a cell's DNA gets corrupted; this is a mutation . The body normally shuts  down or eliminates this mutated cell by a process called apoptosis but sometimes the cell replicates so quickly that it couldn't be eliminated and this is cancer. The cell rapidly divides with infinite supply of telomere's and therefore can keep replicating without a stop.  Normally these cells are taken out by a surgery if they are grown only in a single part of the body. Radiation therapy can also used when only one part of an organ is damaged. The radiation is given from an external source and with great accuracy. Therefore, radiation is used to eliminate only cancer cells while leaving out the healthy tissue. Sometimes the cancer cells travel out of the mutated region and into the blood capillaries. Then, these cancer cells  circulate and start growing in another organ. At this stage, chemotherapy is used, which are drugs that travels all over th...

Lotions are applied to external skin with bare hands, a clean cloth, cotton wool or gauze . Many lotions, especially hand lotions and body lotions are formulated not as a medicine delivery system, but simply to smooth, re-hydrate, and soften the skin. These are particularly popular with the aging and aged demographic groups, and in the case of face usage, can also be classified as a cosmetic in many cases, and may contain fragrances. Most lotions are oil-in-water emulsions using a substance such as cetearyl alcohol to keep the emulsion together, but water-in-oil lotions are also formulated. The key components of a skin care lotion, cream or gel emulsion (that is mixtures of oil and water) are the aqueous and oily phases, an emulgent to prevent separation of these two phases, and, if used, the drug substance or substances.
