Thedreaded pathogenic bacterium J. grocious makes a toxin called BalD. There are two allelic forms of balD, with the balD-1 allele encoding the more potent form of the toxin, and balD-2 allele encoding the less potent form of the toxin. Every person in Champaign-Urbana is infected with one of two possible strains of J. grocious, which differ only in whether the strain carries balD-1 allele or balD-2 allele. If the allelic frequency of J. grocious strains carrying the balD-1 allele is 0.8 in Champaign (population = 80,000), and 0.6 in (Urbana = 50,000), then what is the allelic frequency of J. grocious strains carrying the less toxic balD allele within the population of the combined cities of Champaign-Urbana?

it's the release of intestinal gas, which forms as a result of digesting food. when partially digested carbs reach the colon, bacteria convert part of that food into hydrogen and carbon dioxide gasses. you cant stop the stink, its a gas that comes naturally.

explanation:

blue stars have the highest surface temp

stellar distances are usually expressed in light-years

the measure of a star's brightness is called magnitude

hope this !

they had the law tat factories that produces smoke cannot be built near residential buildings.

building of proper sewage system was done to ensure that the waste is carried away from the humans so that they do not get diseases from it.

also they built water systems to provide water in those areas which are drought prone.
