Expression of the a and b antigens on red blood cells is influenced by the fut1 gene. this gene encodes fucosyl transferase, an enzyme that produce the h substance. which of the following statements about the h substance is incorrect?
(a) individuals that cannot produce the h substance appear to be type o even if they have functional a and/or ib alleles.
(b) individuals that fail to produce the h substance are said to have the bombay phenotype.
(c) individuals that are heterozygous for the fut1 gene cannot produce the h substance
(d) the h substance is a substrate for the enzymes produced by the n and β genes. these enzymes add the appropriate terminal sugar to the h substance producing the a and b antigens, respectively.

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.
