The genes kn-1 (produces leaves with small "knots") and d3 (causes dwarfed stature) are 40 map units apart on chromosome 1 of corn. the distance between these two loci was determined using a corn line with no known inversions on chromosome 1. a paracentric inversion of 20 map units lies between (but not containing) kn-1 and d3 in popcorn lines. if the distance between the two loci was mapped using a heterozygote with one normal chromosome 1 and one paracentric inversion chromosome 1, what is the apparent distance between the two loci?

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
