Humans are obligate aerobes requiring functional mitochondria, yet mutations in mtDNA exist that disrupt electron transport. Why are these mutations NOT lethal? A heteroplasmic condition is maintained with a mixture of normal and mutated mitochondria in the cell. The mutations are always in non-essential functions. Nuclear genes compensate for the mutation by providing the missing gene product. The cells compensate by increasing glycolysis.

Problem 6 (10 points) 6. For each of the multiplication problems below: • Find a way to use the properties of arithmetic (associative, commutative, and distributive) to make the problem easy to solve mentally. You may use whatever property or combination of properties you like, so long as it makes the problem easier to solve mentally according to the standards set by this course. • Write a sequence of equations that correspond to your mental method. Your equations must be true statements. If you claim that two things are equal, they must actually be equal. • Use your equations to clearly identify which properties of arithmetic were used and what they were used for.
