In a particular plant, RR, Rrand Ir are the genotypes for a gene. How many phenotypes are possible if the R is dominant to r?

relative humidity, temperature and dew point -- are bound together in the mathematical relationship below. relative humidity changes when temperatures change. because warm air can hold more water vapor than cool air, relative humidity falls when the temperature rises if no moisture is added to the air. so i would say a

well, that's easy; the answer's c, "it reduces contamination of the water and substrate of the estuary."
