Use the following information to answer the questions below. Mouse mutations can affect an animal's appetite and eating habits. The ob gene codes for a satiety factor, the hormone leptin. The db gene product, the leptin receptor, is required to respond to the satiety factor.
Leptin is a product of adipose cells. Therefore, a very obese mouse would be expected to have
Select one:
a. mutation of ob or db
b. increased gene expression of db and decreased expression of ob
c. increased gene expression of ob and decreased expression of db.
d. decreased transcription of both ob and db

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.
