Imagine an island archipelago where all of the islands are founded by individuals that are heterozygous at a particular locus. If there is no migration or mutation, and the alleles at that locus are neutral, what do you expect the island populations to look like after many generations?

a) Some island populations will have fixed one allele, and other populations will have fixed the other allele.
b) The populations on every island will have fixed the same allele.
c) The island populations will have high levels of genetic diversity at this locus.
d) We cannot assess the probability of any outcome because genetic drift is a random process.

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
