Writing Guide 2021-12-21T00:00:00Z Before equilibrium was reached, the solution with more sugar was hypertonic, or “above strength,” and the solution with less sugar was hypotonic, or “below strength.” Miller & Levine Biology 2018-01-01T00:00:00Z An eccrine sweat gland is type of gland that produces a hypotonic sweat for thermoregulation. Anatomy and Physiology 2013-06-19T00:00:00Z In a hypotonic solution, such as tap water, the extracellular fluid has a lower concentration of solutes than the fluid inside the cell, and water enters the cell. Concepts of Biology 2013-04-25T00:00:00Z As seen in Figure 32.2, a cell placed in water tends to swell due to gain of water from the hypotonic or “low salt” environment. Biology for AP Courses 2022-06-09T00:00:00Z “Some do a dance to try to hypotonic the female so she doesn’t strike,” Urban explains. 'Ding dong, it's time': dancing tarantulas emerge in droves to mate in western US 2019-09-07T04:00:00Z The terms isotonic, hypertonic, and hypotonic refer the “strength,” or concentration, of the sugar solute, not the water. Miller & Levine Biology 2018-01-01T00:00:00Z In contrast, a solution that has a lower concentration of solutes than another solution is said to be hypotonic, and water molecules tend to diffuse out of a hypotonic solution. Anatomy and Physiology 2013-06-19T00:00:00Z All isolated cells were depleted of erythrocytes by hypotonic lysis. Effective combinatorial immunotherapy for castration-resistant prostate cancer : Nature : Nature Research 2017-03-19T04:00:00Z In a hypotonic environment, cells tend to swell due to intake of water. Biology for AP Courses 2022-06-09T00:00:00Z The tap water, it turned out, was hypotonic—a low-pressure solution that caused the cells to swell, like a deflated raft being blown up with too much air. The Story Behind a Miracle Cancer Drug [Excerpt] 2013-05-10T14:15:00.380Z A bipolar field has a hypertonic pole or centre of concentration, and a hypotonic pole or centre of dilution. The Mechanism of Life Cells in a hypotonic solution will take on too much water and swell, with the risk of eventually bursting. Anatomy and Physiology 2013-06-19T00:00:00Z Some organisms, such as plants, fungi, bacteria, and some protists, have cell walls that surround the plasma membrane and prevent cell lysis in a hypotonic solution. Biology for AP Courses 2022-06-09T00:00:00Z In such hypotonic environments, these fish do not drink much water. Biology for AP Courses 2022-06-09T00:00:00Z They perfected the hypotonic solution, still used in molecular genetics today, and figured out how to air-dry slides to help the cells spread out even more. The Story Behind a Miracle Cancer Drug [Excerpt] 2013-05-10T14:15:00.380Z These particles are drawn along with the water stream which passes from the hypotonic centres or regions toward those which are hypertonic. The Mechanism of Life A hypotonic solution has a solute concentration lower than another solution. Anatomy and Physiology 2013-06-19T00:00:00Z Freshwater fish live in an environment that is hypotonic to their cells. Biology for AP Courses 2022-06-09T00:00:00Z Water, which is hypotonic with respect to body fluids. Biology for AP Courses 2022-06-09T00:00:00Z When immersed in a hypertonic solution, it retracts; in a slightly hypotonic solution it absorbs water and becomes turgescent, while in a very hypotonic solution it swells up and bursts. The Mechanism of Life On the right a grain of salt forming a hypertonic pole of concentration, on the left a drop of blood forming a hypotonic pole of dilution. The Mechanism of Life This type of sweat, released by exocytosis, is hypotonic and composed mostly of water, with some salt, antibodies, traces of metabolic waste, and dermicidin, an antimicrobial peptide. Anatomy and Physiology 2013-06-19T00:00:00Z In a hypotonic solution they swell up and burst, the h�moglobin dissolving in the liquid and colouring it red. The Mechanism of Life What tends to happen to cells in a hypotonic environment? Biology for AP Courses 2022-06-09T00:00:00Z During a surgical operation it is of the first importance not to injure the living surfaces by flooding them with strongly hypertonic or hypotonic solutions. The Mechanism of Life By analogy with the magnetic and electric fields we may designate the hypertonic pole as the positive pole of diffusion, and the hypotonic as the negative pole. The Mechanism of Life As a result of this aggregation the number of molecules in a given area is diminished, i.e. the concentration and the osmotic pressure fall, producing a hypotonic centre of diffusion. The Mechanism of Life These give it an osmotic pressure which prevents the deleterious effects of a strongly hypotonic liquid. The Mechanism of Life In a hypotonic situation, the extracellular fluid has lower osmolarity than the fluid inside the cell, and water enters the cell. Biology for AP Courses 2022-06-09T00:00:00Z Under the influence of such a hypotonic solution the dry cells rapidly swell up, burst, and are dissolved. The Mechanism of Life We have thus two poles of diffusion of contrary signs, a hypotonic pole at the water drop, and a hypertonic pole at the salt drop. The Mechanism of Life It gains weight in a hypotonic solution, the water current setting towards the point of higher concentration. The Mechanism of Life When comparing two solutions of different concentration, the solution with the higher osmotic pressure is said to be hypertonic, and that with the lower osmotic pressure hypotonic.
