Most individuals of the same species, whether African elephants, portobello mushrooms, white oak trees, or humans, have nearly identical DNA. But the DNA sequence at certain locations, or loci, throughout the genome
varies among individuals. These variations can be used to distinguish one individual from another of the same
species. The process of analyzing these DNA variations for the purpose of identification is known as DNA profiling,
or genetic fingerprinting.

The graphic below represents a gel electrophoresis that was run during a crime scene investigation to create a DNA profile. Column 1 represents DNA found at the scene of the crime. Columns 2-5 are DNA samples obtained from suspects.

Analyze the DNA profile evidence obtained from gel electrophoresis by completing the following questions:

Identify which suspect(s) can be excluded.
Identify which suspect(s) cannot be excluded.
Explain how you reached your answer to parts a & b.

Sea stars, sea urchins, sand dollars, and brittle stars are all memeber of a group, what is the common name of the group they are all in

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.
