Potassium has a density of 0.86 g/cm^3, an atomic weight of 39.0983 g/mol, and contains 0.012% of Potassium-40 which is radioactive by beta-decay with a half-life of 1.25x10^9 years.
a. What is the total and average binding energy of potassium-40?
b. If the average mass of potassium within the human body is about 140 g, estimate the average activity (in bq) of [40,19] K in the body.

The biologist and anthropologist Jared Diamond stated that “agriculture is the worst mistake in the history of the human race”. Based on your knowledge of genome evolution and phylogenetics (and other aspects of genetics/biology), provide arguments for and against this statement. Also give your opinion on this in the context of the United Nations Sustainable Development Goals of zero hunger; good health and wellbeing; and responsible consumption and production (Goals 2, 3 and 12).
