Which of the following is an important difference between light-dependent and light-independent reactions of photosynthesis? the light-dependent reactions occur only during the day; the light-independent reactions occur only during the night. a the light-dependent reactions occur in the cytoplasm; the light-independent reactions occur in chloroplasts. b the light-dependent reactions utilize co2 and h2o; the light-independent reactions produce co2 and h2o. c the light-dependent reactions depend on the presence of both photosystems i and ii; the light-independent reactions require only photosystem i. d the light-dependent reactions produce atp and nadph; the light-independent reactions use energy stored in atp and nadph.

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.
