Essay content:

Our hypothesis is that an environment with a concentration between 10-8 M and 10-10M of hydrogen peroxide will result in the highest successful fertilized sea urchin egg count. Sea urchin eggs and sperm were placed in separate test tubes with hydrogen peroxide concentrations of 10-1 to 10-12 M. Fifteen eggs were selected from each test tube and recorded to be fertilized, unfertilized, or abnormal...
