Data analysis aquatic organism ph range for life clam 4.5 - 5.0 snail 5.0 - 9.0 bass 5.5 - 9.0 crayfish 5.5 - 8.5 mayfly 5.5 - 9.0 salamander 6.0 - 8.0 trout 6.0 - 8.5 perch 6.5 - 8.5 frog 7.0 - 9.5 the epa has recommended water quality criteria that include the ph in both freshwater and salt water. the recommended ph range for freshwater is 6.5 to 9.0, and for salt water it is 6.6 to 8.5. in the eastern united states, 75% of the lakes have a ph in the acidic range, from 6.5 to 4.2. based on this new information, what species are most likely to survive in eastern u. s. lakes, if the ph drops and remains at 4.2? a) frogs b) clams and snails c) none of the species would survive d) frogs, perch, trout, salamanders

How many chromosomes are in a gold fish?

It is believed that europa, one of jupiter’s moons has an ocean beneath its surface. based on how earth’s oceans and atmosphere are believed to have formed, what can be said about europa’s supposed ocean? the arrival of in the early days of europa’s existence could have formed its ocean. it is likely that the water experienced , similar to earth. it is also possible that this water is retained beneath europa’s surface and in its atmosphere due to europa’s .

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.
