in the condensation of the water-vapour of the air on the cold surface of a glass; in the capillarity of hair, wool, cotton, wood shavings, etc.; in the imbibition of water from the air by gelatine; in the deliquescence of common salt; in the absorption of water from the air by concentrated sulphuric acid; in the behaviour of quicklime".

Maintains the intraocular pressure and inflates the globe of the eye. It is this hydrostatic pressure that keeps the eyeball in a roughly spherical shape and keeps the walls of the eyeball taut. Provides nutrition (e.g. amino acids and glucose) for the avascular ocular tissues; posterior cornea, trabecular meshwork, lens, and anterior vitreous.
There are not four primary tastes, but five: in addition to bitter, sour, salty, and sweet, humans have taste receptors for umami, which is a "savory" or "meaty" taste. [495] Fat does interact with specific receptors in taste bud cells, but whether it is a sixth primary taste remains inconclusive. [496] The human sense of smell is not weak or ...
Saliva on a baby's lips. Saliva (commonly referred to as spit or drool) is an extracellular fluid produced and secreted by salivary glands in the mouth.In humans, saliva is around 99% water, plus electrolytes, mucus, white blood cells, epithelial cells (from which DNA can be extracted), enzymes (such as lipase and amylase), and antimicrobial agents (such as secretory IgA, and lysozymes).
Similar to wine, “water is actually 100% terroir driven,” meaning a particular region’s climate and soil where the water is sourced affect its taste, explains Riese. “You can actually ...
Dryness is a property of beverages that describes the lack of a sweet taste. [1] This may be due to a lack of sugars, the presence of some other taste that masks sweetness, or an underabundance of simple carbohydrates that can be converted to sugar by enzymes in the mouth (amylase in particular).
Additionally, many D- enantiomers of proteinogenic amino acids have a sweet taste, even when their L- enantiomer lacks any sweet taste, such as in the case of D-asparagine versus L-asparagine. [15] The sweetness of 5% solution of glycine in water compares to a solution of 5.6% glucose or 2.6% fructose. [16]
