The nucleus of a cell contains genetic material and many proteins. the interaction between these proteins and genetic material forms various structures. match each of the following terms with the statement that describes the term.
1. protein
2. dna
3. chromatin
4. histones

a. this series of nucleotides encodes proteins.
b. these proteins regulate transcription and modifications of genetic material.
c. this folded amino acid chain is genetically encoded and performs specific functions in the cell.
d. this substance is made up of fibers that are formed in the nucleus by supercoiling genetic material.

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.
