Suppose a researcher for a pest-control company developed a chemical that inhibited the development of an embryonic mosquito’s endodermal cells. which of the following would be a likely mechanism by which this pesticide works?
a. the mosquito would develop a weakened exoskeleton that would make it vulnerable to trauma.
b. the mosquito would have trouble digesting food, due to impaired gut function.
c. the mosquito would have trouble with respiration and circulation, due to impaired muscle function.
d. the mosquito wouldn't be affected 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.
