Jelly babies [4] or gummy bears [5] are often used for theatrics. Potassium chlorate, a strong oxidising agent, rapidly oxidises the sugar in the candy causing it to burst into flames. The reaction produces a "screaming" sound as rapidly expanding gases are emitted from the test tube. [6] The aroma of caramel is given off. [7]
Gummy bears (German: Gummibär) are small, fruit gum candies, similar to a jelly baby in some English-speaking countries. The candy is roughly 2 cm (0.8 in) long and shaped in the form of a bear. The gummy bear is one of many gummies, popular gelatin-based candies sold in a variety of shapes and colors by various brands such as Haribo.
Osmoregulation is the active regulation of the osmotic pressure of an organism's body fluids, detected by osmoreceptors, to maintain the homeostasis of the organism's water content; that is, it maintains the fluid balance and the concentration of electrolytes (salts in solution which in this case is represented by body fluid) to keep the body fluids from becoming too diluted or concentrated.
The process of osmosis over a semipermeable membrane.The blue dots represent particles driving the osmotic gradient. Osmosis (/ ɒ z ˈ m oʊ s ɪ s /, US also / ɒ s-/) [1] is the spontaneous net movement or diffusion of solvent molecules through a selectively-permeable membrane from a region of high water potential (region of lower solute concentration) to a region of low water potential ...
An osmometer is a device for measuring the osmotic strength of a solution, colloid, or compound.. There are several different techniques employed in osmometry: Freezing point depression osmometers may also be used to determine the osmotic strength of a solution, as osmotically active compounds depress the freezing point of a solution.
Effect of different solutions on red blood cells Micrographs of osmotic pressure on red blood cells. In chemical biology, tonicity is a measure of the effective osmotic pressure gradient; the water potential of two solutions separated by a partially-permeable cell membrane.
Called the "I Turn Polar Bears White" riddle, it presents a series of cryptic statements that don't seem to make sense at first glance. Take a closer look at this perplexing puzzle and see if you ...
Semipermeable membrane is a type of synthetic or biologic, polymeric membrane that allows certain molecules or ions to pass through it by osmosis. The rate of passage depends on the pressure, concentration, and temperature of the molecules or solutes on either side, as well as the permeability of the membrane to each solute.
