In cosmos plants, purple stem (a) is dominant to green stem (a), and short petals (b) is dominant to long petals (b). in a simulated cross, aabb plants were crossed with aabb plants to generate f1 dihybrids (aabb), which were then test crossed (aabb x aabb). 900 offspring plants were scored for stem color and flower petal length. the hypothesis that the two genes are unlinked predicts the offspring phenotypic ratio will be 1: 1: 1: 1. using the ratio of 1: 1: 1: 1, calculate the expected number of each phenotype out of the 900 total offspring. drag the correct values onto the data table. labels may be used once, more than once, or not at all.

Where does all the water go? according to the environmental protection agency (epa), in a typical wetland environment, 39% of the water is outflow; 46% is seepage; 7% evaporates; and 8% remains as water volume in the ecosystem (reference: united states environmental protection agency case studies report 832-r-93-005). chloride compounds as residuals from residential areas are a problem for wetlands. suppose that in a particular wetland environment the following concentrations (mg/l) of chloride compounds were found: outflow, 60.4; seepage, 73.7; remaining due to evaporation, 26.4; in the water volume, 46.8. (a) compute the weighted average of chlorine compound concentration (mg/l) for this ecological system. (round your answer to one decimal place.) mg/l (b) suppose the epa has established an average chlorine compound concentration target of no more than 58 mg/l. does this wetlands system meet the target standard for chlorine compound concentration? yes. the average chlorine compound concentration (mg/l) is too high. yes. the average chlorine compound concentration (mg/l) is lower than the target. no. the average chlorine compound concentration (mg/l) is lower than the target. no. the average chlorine compound concentration (mg/l) is too high.
