3. How did the invention of the light microscope
lead to the development and refinement of cell
theory over time?
A. Cells could now be seen in very low light so
that studies of reproduction could take place at
night.
B. Light microscopes allowed for the visualization
of internal cell parts at magnifications over
1,000 times.
C. As microscopes became more powerful,
scientists could see additional structures and
functions within the cell.
D. Scientists kept what they saw through the lens
of the light microscope to themselves to be sure
they got all the credit for the discovery.

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.
