We have seen that a centre of catabolism is a hypertonic focus of diffusion.
If such eggs are afterwards treated for a short period with hypertonic sea-water they develop into normal larvae (plutei).
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.
Those eggs which form membranes begin to develop, but perish if they are not treated with hypertonic sea-water.
A bipolar field has a hypertonic pole or centre of concentration, and a hypotonic pole or centre of dilution.
Loeb and Wasteneys found that the hypertonic solution does not increase the rate of oxidations in a fertilized egg.
Rogers has reduced the mortality of cholera by intravenous injections of hypertonic saline until it is only 15 per cent.
The concentration of the solution is increased, the osmotic pressure is raised, and we have a hypertonic centre of diffusion.
What does the hypertonic solution do to prevent the disintegration of the egg after the artificial membrane formation?
On either side the pigment of the central drop has been drawn towards the hypertonic centre nearest to it.
hypertonic hy·per·ton·ic (hī'pər-tŏn'ĭk)
Having extreme muscular or arterial tension; spastic.
Having the higher osmotic pressure of two solutions.
