Why is the adaptation in the previous question an advantage in hot, dry climates? (Think about photosynthesis, sun exposure, transpiration rate...) Answers:
A. Small leaves are less susceptible to water loss through evaporation, but photosynthetic rate can improve by increasing leaf density.
B. Large leaves hold on to large amounts of water and the weight of the plant will be too great for small plants to withstand.
C. Small leaves prevent animals from nesting in the plant structure preventing plants from being eaten.

In which state was more than 100 billion tons of coal mined in 2005?

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
