1. The rate of forward movement in Paramecium as affected by changes in temperature can be described accurately in terms of the Arrhenius equation. See PDF for Equation 2. For the range from 6-15 degrees , micro = 16,000; from 16-40 degrees , micro = 8,000. These values fall within the limits characteristic for chemical processes. 3. On the principle of(More)
1. Frequency polygons in which the number of observations at each temperature is reduced to a percentage basis while the time factor is represented on a logarithmic scale, indicate that the time required by Paramecium to swim a unit distance at different temperatures varies within definite limits which are constant above 15 degrees . Below 15 degrees the(More)
1. For the heart rate in Pterotrachea coronata, intermediate temperatures disclose a thermal increment of 11,200 +/-. This value is identical with the one reported by Crozier and Stier for the lamelli-branch, Anodonta. In the pteropod, Tiedemannia neapolitana the same temperatures typically reveal in the heart rate a micro value of 16,200 +/- This agrees(More)
