In which of the following ways does a fertilized egg differ from an unfertilized egg?

well, I would start with the main most fact: The unfertilized egg will NOT develop, in other words, saying that the egg would die. whilst the fertilized egg would develop, and be given life.

The answer to this will be from your lab notes/procedure. it would be best to ask another student who participated in the lab as we do not know what was done, what enzyme or if the temperature is celsius or fahrenheit. if i were to guess though i'd say the rate stopped due to enzyme denturing at high temperature
