The urine osmolality is the measurement of urine absorption, which substantial values indicate concerted urine and small values specify weaken urine. Any foods that contained water also affects the osmolality of urine. Some of the mammals are competent of higher osmolality than healthy humans, most especially the rats, hamsters, and mice if given no water.

Answer from: sara6689

Osmolality is measured by an osmometer, which evaluates the freezing point depression of a solution and gives results as milliosmol per kilogram of water, while specific gravity is measured by a colorimetric strip, refractometer, hydrometer, and pycnometer.

Further explanation

Urine osmolality is a measure of urine concentration, where large values indicate concentrated urine and small values indicate runny urine. Water consumption (including water contained in food) affects urine osmolality. In healthy humans with limited fluid intake, urine osmolality must be greater than 800 mOsm / kg, while 24-hour urine osmolality must average between 500 and 800 mOsm / kg.

Urinary osmolality in humans can range from around 50 to 1,200 mOsm / kg, depending on whether the person has recently drunk large amounts of water (lower amounts) or has been without water for a long time (higher amounts). Plasma osmolality with a typical fluid intake often averages around 290 mOsm / kg H 2 O in humans.

the study states that the main stimulus that stimulates ADH expenditure during exercise is an increase in osmolarity pressure caused by the release of sweat and moisture through excessive respiration. If the osmolarity of body fluids increases above normal the solutes in the body fluid become concentrated, the posterior pituitary gland will secrete more ADH. This situation allows the reabsorbtion of large amounts of water and a decrease in urine volume but does not significantly change the rate of excretion dissolved by the kidneys.

Mantle convection is the slow creepingmotion of earth's solid silicate mantle caused by convection currents carrying heat from the interior to the planet's surface.[1][2] the earth's surface lithosphere, which rides atop the asthenosphere (the two components of the upper mantle), is divided into a number of plates that are continuously being created and consumed at their opposite plate boundaries. accretion occurs as mantle is added to the growing edges of a plate, associated with seafloor spreading. this hot added material cools down by conduction and convection of heat. at the consumption edges of the plate, the material has thermally contracted to become dense, and it sinks under its own weight in the process of subduction usually at an ocean trench.[3]this subducted material sinks through the earth's interior. some subducted material appears to reach the lower mantle,[4] while in other regions, this material is impeded from sinking further, possibly due to a phase transition from spinel to silicate perovskiteand magnesiowustite, an endothermic reaction.[5]the subducted oceanic crust triggers volcanism, although the basic mechanisms are varied. volcanism may occur due to processes that add buoyancy to partially melted mantle causing an upward flow due to a decrease in density of the partial melt.secondary forms of convection that may result in surface volcanism are postulated to occur as a consequence of intraplate extension[6] and mantle plumes.[7]it is because the mantle can convect that the tectonic plates are able to move around the earth's surface.[8]mantle convection seems to have been much more active during the hadean period, resulting in gravitational sorting of heavier molten iron, and nickel elements and sulphides in the core, and lighter silicate minerals in the mantle.
