Mitochondria with extensive cristae are generally found in aerobic tissue cells that produce large quantities of ATP, such as muscle cells. Which of the following best describes how the increased amount of cristae in mitochondria leads to more efficient ATP production? The volume of the mitochondria matrix is increased.
The volume of the intermembrane space is increased.
The total number of ribosomes that synthesize ATP-producing protein complexes is increased.
The total number of main ATP-producing protein complexes on the inner mitochondrial membrane is increased.

For the strategies below, decide whether they are best described as demand-side solutions or supply-side solutions to meeting human needs for fresh water. remember that a demand-side solution reduces demand for fresh water, whereas a supply-side solution increases the supply of fresh water. (a) damming a river to create a reservoir (b) desalinating seawater (c) a nation invading a neighboring country to access their rivers (d) raising water prices for consumers and businesses (e) providing tax breaks for companies that use less water (f) replacing inefficient irrigation with more-efficient drip irrigation to grow crops (g) requiring low-flow showerheads in all new homes
