hybridization and genetic modification are two methods to improve the annual yield of crops, get better seed and fruits, and produce disease-resistant crops.
what is a reason for choosing hybridization over genetic modification?
a) genetically modified crops are much cheaper to produce.
b) genetically modified crops may increase the risks of allergic reactions.
c) initial attempts at genetic modification did not produce the desired results.
d) genetically modified crops are resistant to some strains of harmful bacteria.

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
