Why does the enzyme trypsin get deactivated when introduced in the gastric juice of the stomach? the optimum ph for trypsin is about 8.0, which is the ph of the intestine, whereas the ph of gastric juice is 1.5 - 2.0, which is highly acidic. the optimum ph for trypsin is about 2.0, which is the ph of the intestine, whereas the ph of gastric juice is 8.0, which is highly alkaline. the optimum temperature for trypsin is about 98.6°f (37°c), which is the temperature of the intestine; whereas the temperature of gastric juice is 392 - 482°f (200°c - 250°c).

Read the following scenario to answer the following question. over the past 60 years, many amphibian species have experienced significant population declines, and some species have become extinct. scientists suspected that local human activities such as the destruction of wetlands, regional pollution, and deforestation were the main reasons for these losses. however, research over the past 20 years reveals significant amphibian population declines in protected areas of the world, such as nature preserves and parks. these global declines suggest widespread problems including increased ultraviolet radiation, acid rain, and disease. in switzerland, for example, 14 of the 20 native amphibian species are threatened with extinction. when most populations of a wide-ranging amphibian species are lost and the few remaining populations are widely separated, we expect to see that a. the founder effect becomes increasingly important b. microevolution no longer occurs c. gene flow between populations is reduced d. artificial selection becomes a greater factor in microevolution

Ayoung boy has been found and police are trying to locate his family they take a dna sample from him and begin collec dna samples from families who have missing children if police use dna samples only from the fathers, which type of dn technology can they use to identify the boy's parent? y-chromosome analysis omtdna (mitochondrial dna) analysis vntrs (variable tandem repeats) o pcr (polymerase chain reaction) analysis
