Suppose that you are a scientist comparing the energy that orchids use for developing flowers to the energy that orchids use to produce nectar. Your research produces the following hypothetical graph. These data make you curious if orchids that allocate less energy to producing nectar (and therefore produce less nectar) reproduce less frequently. Which of the following might be your hypothesis? (Select all that apply.)

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
