16) The sexually transmitted disease gonorrhea has become increasingly resistant to treatment withantibiotics.What is the most likely scientific explanation?a.The gonorrhea bacteria learned to avoid antibioticsb.Antibiotic-sensitive gonorrhea bacteria died out, but antibiotic-resistant gonorrheabacteria survived and multipliedc.The gonorrhea bacteria changed their genes when they sensed antibioticsd.The antibiotic decreased the mutation rate in the gonorrhea bacteria
17) Biomedical researchers study species as disparate as worms, fruit flies, mice, zebrafish, or rhesusmonkeys to understand our genes, and even our diseases.Why?
18) Mendel discovered that whether his peas were yellow or green is determined by a single gene inwhich yellow (Y) is dominant over green (y). Assuming low selective pressure, what does theHardy-Weinberg Equilibrium frequency term 2pq represent in the peas?

19) Afer a drought in 1977, the number of birds on Daphne Major Island decreased by ____ timescompared with the original population size.
20) Consider Mendel's pea plants in which a single gene determines whether the peas are yellowfrom the dominant allele Y or green from the recessive allele y (when both alleles are y).According to the Hardy-Weinberg Principle of Equilibrium, what is the frequency of heterozygousindividuals in a population under low selective pressure?a.p + q = 1b.p2c.2pq
