3. Antibiotic-resistant bacteria may expend extra energy and resources to produce special compounds and carry extra genetic material to protect
themselves against antibiotics. Predict what might happen to these bacteria if
they are not exposed to antibiotics for many generations.

(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
