The activity of two enzymes, pepsin and trypsin, are shown here. these are two enzymes involved in the digestion of food in
the stomach and small intestine. at which ph would the activity of both enzymes have the same catalyzing rate?

answer; /// i believe that the correct answer is (50%);

the oxygenated blood then leaves the lungs through pulmonary veins, which return it to the left heart, completing the pulmonary cycle. this blood then enters the left atrium, which pumps it through the mitral valve into the left ventricle. from the left ventricle, the blood passes through the aortic valve to the aorta.

deoxygenated blood leaves through the right ventricle through the pulmonary artery. from the right atrium, the blood is pumped through the tricuspid valve (or right atrioventricular valve), into the right ventricle.

the dna of humans and mice is almost 92% similar. this similarity indicates that . mice have a tail, while humans have a tailbone. the tailbone is a structure in humans.yes it's true.

a and c are the answeres
