Asolution of an enzyme normally found in the human body was added to a flask containing a solution of proteins in distilled water, and then the flask was stoppered. this mixture was then maintained at a temperature of 27 degrees celsius and a ph of 7 for 48 hours. when the mixture was analyzed, the presence of amino acids was noted. one way to speed up the production of amino acids in the flask would be to

1. increase the temperature from 27 degrees celsius to 37 degrees celsius
2. increase the ph from 7 to 12
3. place the flask in bright light
4. decrease the amount of enzyme added

1. increase the temperature from 27 degrees Celsius to 37 degrees Celsius

Explanation:

Generally, protease function optimally at temperature range of 55 to 60 degrees Celsius and at lower pH 5.0 to 5.5. Hence increase in temperature to 37 degrees Celsius will increase proteolysis.

just here for the other one bc they put up with u

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.
