The correct answer is C. Populations of organisms rarely change over time
Explanation:
In biology, living organisms differ from non-living ones according to different features, this includes the ability to replicate or reproduce sexually or asexually; the metabolization of energy to different activities such as growth or reproduction; a complex system that allows them to live and the ability to adapt to the environment. This last idea implies organisms and populations of them change over time according to the environment and therefore the one that is not a property of life is that "populations of organisms rarely change over time".
The deeper you go down in to the rock the older the fossils get. So when the scientists go in to the rock they can say what animals lived in that time and what animal was the oldest.
