As part of a blood drive on campus for the american red cross, you and your friends have just donated 500 ml of blood. you are now relaxing at the student lounge, waiting for a& p lab to begin. unfortunately, even though you are thirsty, you haven't bothered to buy yourself a drink. other than a little soreness of the skin and tissue around your median cubital vein, you feel fine. how has your 500 ml decrease in blood volume most likely affected your cardiac output, heart rate, and stroke volume?

Photosynthesis converts light energy to chemical energy. which molecules are the end product of this transformation of energy in this reaction?

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.
