After sperm had been in the irradiated water for 30 minutes they were used to inseminate fertile eggs in fresh sea water. Cleavage delay is expressed as cleavage time over that of eggs inseminated with control sperm. Lower graph: effect

After sperm had been in the irradiated water for 30 minutes they were used to inseminate fertile eggs in fresh sea water. Cleavage delay is expressed as cleavage time over that of eggs inseminated with control sperm. Lower graph: effects (on cleavage time) of exposing the sperm for different periods of time to irradiated water (224,000 r) and to water containing hydrogen peroxide (1 : 1,000,000). Reduction in toxicity of irradiated water by catalase extract rt was found that a crude extract possessing catalase activity could be removed concentrated sperm This extract could be added to sperm in Report in Please note that these images are extracted from scanned page images that may have been digitally enhanced for readability - coloration and appearance of these illustrations may not perfectly resemble the original Marine Biological Laboratory (Woods Hole, Mass. ); Marine Biological Laboratory (Woods Hole, Mass. ).
