The correct answer is: 'the ability to transform chemical energy into mechanical energy'. The oxidation of fats and carbohydrates through chemical reactions produce adenosine triphosphate (ATP) molecules. These ATP molecules power m<span>uscles, thereby converting chemical energy to mechanical energy.</span>
<span>Molecular clocks use rates of mutation to measure
evolutionary time. Mutations add up at a fairly constant rate in the DNA of
species that evolved from a common ancestor. The more mutations that happened
in each lineage, the greater is the differences between these lineages.</span>
Here's an explanation to help answer the question
Eons are divided into eras, which are in turn divided into periods, epochs and ages. The terms "eonothem", "erathem", "system", "series", and "stage" are used to refer to the layers of rock that correspond to these periods of geologic time in Earth's history.
