Which one of the following statements does not support the hypothesis "dnaa affinity for binding sites at the oric is a mechanism that allows identification of the oric for replication initiation, while at the same time making sure replication starts only when cellular conditions are ready for replication.
a. replication results in a doubling of the oric sites but not a doubling of dnaa protein so that replication does not start right after the last round of replication occurred
b. the promoter for dnaa needs to be fully methylated in order for dnaa synthesis, making the dnaa concentration directly after replication.
c. the chromosome contains dnaa binding sites outside of the oric that decrease the available pool of dnaa in the cell so that the available dnaa will only bind to high affinity sites

Which of the following structures is not found in both plant and animal cells? a) chloroplast b) cytoskeleton c) ribosomes d) mitochondria

An example of a trait that would be considered acquired and inherited is a. a cleft chin b. muscle tone c. scar tissue d. freckled skin

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.
