Two subgroups of a population separated by a river are rejoined when a drought causes the river to run dry. assuming that speciation has not yet occurred, what is true about the two subgroups?

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

Than y you put it in    biology
