Which is a good example of adaptive evolution? the red fox that inhabits farmlands and forests has a red coat, but its relative, the kit fox, lives in a desert has a sandy–colored coat. two birds of the same species separate during their migratory flight. after several years, their descendants are quite different from each other. two species of fish try to swim against the current near a waterfall. one survives, but the other doesn't.

The theories on the expansion of galaxies maybe re-examined to strengthen science should not be tested to strengthen science will weaken scientific knowledge if they change will become laws if they don't change

Asolution of an enzyme and a substrate was placed in a water bath and the temperature of the reaction was raised gradually. the graph shown was plotted at the end of the experiment. what can be concluded from the graph? a) temperature has no effect on the activity of the enzyme. b) the effect of temperature on the enzyme is unpredictable. c) the enzyme shows increased activity up to a certain temperature. d) the activity of the enzyme is inversely proportional to the temperature.
