Tonicity refers to the relative solute concentration of an aqueous solution. Hypertonic solutions have a higher solute concentration, whereas hypotonic solutions have a lower solute concentration. Isotonic solutions have the same solute concentration....
Hypertonic solutions also dehydrate food and other substances, as water leaves cells or passes through a membrane to try to establish equilibrium. Why Students Get Confused The terms "hypertonic" and "hypotonic" often confuse students because they neglect to account for the frame of reference. For ...
Will water move into or out of the fish? Explain. Hypotonic Environment Since freshwater has less salt in it than a fish does, we could say that the freshwater is hypotonic to the fish. Hypotonic is a term used to describe a solution ...
A transference to hypertonic water causes changes in the neurosecretory system which suggest the existence of an antidiuretic principle in the neurosecretory substance. No such relationship is found when the fishes are put into hypotonic water. Further, no connection is found between either the ...
To understand the effects of hypo and hypertonic solutions, you should review the process of osmosis. A hypotonic solution has a lower concentration of electrolytes than the plasma, so when a hypotonic solution is administered intravenously, fluid will come out of the bloodstre...
In hypotonic conditions, which lead to stomatal opening, RFP–AHA1 was located in the plasma membrane, while GFP–PATROL1 seemed to line the membrane (Fig. 4a). In hypertonic conditions, which induce stomatal closure, RFP–AHA1 partially remained in the plasma membrane and GFP–PATROL1 seemed...
A transference to hypertonic water causes changes in the neurosecretory system which suggest the existence of an antidiuretic principle in the neurosecretory substance. No such relationship is found when the fishes are put into hypotonic water. Further, no connection is found between either the ...
Therefore, the process of hyperactivation occurring in mammalian spermatozoa under hypotonic conditions is reminiscent of the high motility of marine fish sperm2,3, and might require the presence of specific mitochondrial detoxification mechanisms. In rodent and human sperm, however, AQP8 is apparently ...
In normal kidneys, which of the following is true of the osmolarity of renal tubular fluid that flows through the early distal tubule in the region of the macula densa?A.Usually isotonic compared with plasmaB.Usually hypotonic compared with plasmaC.Usually hypertonic compared with plasmaD....
drowning. When fresh water enters the lungs it is pulled into the pulmonary circulation by the alveoli. This happens due to the low capillary hydrostatic pressure and high colloid osmotic pressure. As a result, the plasma is diluted and the hypotonic environment causes red blood cells to burst....
