Scientists researching DNA sequences crossed type Q pea plants with type Z pea plants. In resulting offspring, the scientists found that half of the DNA was from type Q and half was from type Z. What is MOST LIKELY the reason for this DNA sequencing in the offspring? A.) Each offspring receives one set of chromosomes from each parent. B.) Each offspring receives RNA from the egg and DNA from the sperm. C.) The offspring from this cross were 50% male and 50% female. D.) The offspring all had the same genotypes, but not the same phenotypes.

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
