What can make HIV even more harmful in the course of a person's infection? Within-host natural selection favors mutant strains that replicate faster. Within-host natural selection favors mutant strains that are better at evading the immune system. Within-host natural selection favors mutant strains that attack a broader range of cell types. All of the above.

Hydrogen and oxygen form both water and hydrogen peroxide. A decomposition of a sample of water forms 0.125 g hydrogen to every 1.00 g oxygen. The decomposition of a sample of hydrogen peroxide forms 0.0625 g hydrogen to every 1.00 g oxygen. Show that these results are consistent with the law of multiple proportions. $\frac{\text{total mass of water}}{\text{total mass of hydrogen peroxide}} = \frac{0.0625 \text{ g}+1.00 \text{ g}}{0.125 \text{ g}+1.00 \text{ g}} = 0.94$ $\frac{\text{mass of hydrogen to 1.00 g oxygen in water}}{\text{mass of hydrogen to 1.00 g oxygen in hydrogen peroxide}} = \frac{0.0625 \text{ g}}{0.125 \text{ g}} = 0.500$ $\frac{\text{mass of hydrogen to 1.00 g oxygen in water}}{\text{mass of hydrogen to 1.00 g oxygen in hydrogen peroxide}} = \frac{0.125 \text{ g}}{0.0625 \text{ g}} = 2.00$ $\frac{\text{total mass of water}}{\text{total mass of hydrogen peroxide}} = \frac{0.125 \text{ g}+1.00 \text{ g}}{0.0625 \text{ g}+1.00 \text{ g}} = 1.06$
