*Why do we say nice sweet. Hah its bitter, Ono its sour , Gosh its salty, Hmm its umami ....?
The reason is :
Taste buds*
Humans perceive taste through sensory organs called taste buds, or gustatory calyculi, concentrated on the top of the tongue. There are between 2000 and 5000 taste buds that are located on the back and front of the tongue. Others are located on the roof, sides and back of the mouth, and in the throat.
The sensation of taste can be categorized into five basic tastes: sweet, bitter, sour, salty and umami. Taste buds are able to differentiate between different tastes through detecting interaction with different molecules or ions. Sweet, umami, and bitter tastes are triggered by the binding of molecules to G protein-coupled receptors on the cell membranes of taste buds. Saltiness and sourness are perceived when alkali metal or hydrogen ions enter taste buds, respectively.
As taste senses both harmful and beneficial things, all basic tastes are classified as either aversive or appetitive, depending upon the effect the things they sense have on our bodies. Sweetness helps to identify energy-rich foods, while bitterness serves as a warning sign of poisons
*What is the living creature which tastes with it's feet ???
Butterfly*
They taste with sensors in their feet.
With few exceptions, adult butterflies eat only various liquids to maintain their water balance and energy stores.
Most butterfly adults sip flower nectar, but other imbibe fluids from sap flowers on trees, rotting fruits, bird droppings, or animal dung. Many adult butterflies are found drinking fluids at wet sand or mud, especially along stream courses or the edges of dirt roads or trails. Some exceptions are the adults of longwing butterflies such as the Zebra are able to collect pollen from certain flowers with their proboscis and to break it down and absorb amino acids (proteins) which contribute to the ability to survive, mate and lay eggs for long periods (6 months or so).
With their short proboscis (tongue) the adults of Harvester butterflies can actually pierce the bodies of woolly aphids and drink their fluids--this would be the only bugs that adult butterflies eat. The caterpillar of almost all butterflies eat various parts of plants. Each species may specialize of only a few kinds of plants or plant parts. The caterpillars of the Harvester butterfly and its relatives are exceptions in that they feed solely on aphids
*What happens to pearl when dipped in vinegar??
It melts*
Pearls are comprised of about 90 per cent calcium carbonate, a small amount of water, and Conchiolin which is an organic protein present to bind the crystals. The pearl is composed of calcium carbonate
Well, vinegar won't actually melt a pearl, but the acids will definitely dissolve one. Pearls are mostly calcium carbonate. Vinegar, which is mostly acetic acid, dissolves calcium carbonate over time. The same dissolution would occur if an egg were placed in a glass of vinegar and left to sit — the egg shell would disintegrate.
*Do we smell stuff while sleeping???
No, If you can smell than you are not sleepin.*
Smell is the first one of your senses to diminish when sleeping, more so for some people than others.
Happy Reading.
