Amylase becomes denatured at a temperature of 80°c. during an experiment to study the effect of varying temperature on enzyme activity, amylase's reactivity with starch was measured at body temperature (37°c), and then again at an increased temperature of 42°c. how would this increase in temperature affect the experiment

1. variations in a population of moths allow for some of its members to be able to adapt to environmental changes. the better adapted of the moths will be able to survive the change and thus prevail as the “fittest” of the species. (a) describe three mechanisms in which variation can occur within a species population. (b) explain which mechanism or mechanisms would be responsible for the survival of a population of peppered moths better than white moths in an environment affected by industrial soot. justify your answer.
