متن کاملFurther Studies on the Kinetics of Osmosis in Living Cells
Using unfertilized eggs of Arbacia punctulata as natural osmometers an attempt has been made to account for the course of swelling and shrinking of these cells in anisotonic solutions by means of the laws governing osmosis and diffusion. The method employed has been to compute permeability of the cell to water, as measured by the rate of volume change per unit of cell surface per unit of osmoti...

WE HAVE ATTEMPTED TO ANSWER THE QUESTION: How nearly ideal, as an osmometer, is the unfertilized Arbacia egg? The following conclusion have been reached: 1.

The product of volume and pressure is approximately constant, ...

متن کاملVertical distribution of three namatode species in relation to certain soil properties.
Population densities of Belonolaimus longicaudatus, Pratylenchus brachyurus, and Trichodorus christiei were determined from soil samples taken weekly in Tifton, Georgia during a 14-month period (except for April and May) at 15-cm increments to a depth of 105 cm. Belonolaimus longicaudatus predominately inhabited the top 30 cm of soil that was 87-88% sand, 6-7% silt, and 5-7% clay. No specimens ...
