Answer:

Explanation:

The circulatory system consists of typically two organs these are the heart which also belong to the cardiovascular system and the lungs which also belong to the respiratory system these are connected to the arteries, veins and other blood vessels. The lungs receives the oxygen which diffuse oxygen into the blood vessels which transports the oxygenated blood to the heart which is pumped and circulated by the heart to all the parts of the body.

Answer:

C. containing

egg albumen
protease
dilute hydrochloric acid

Explanation:

A protease is a kind of peptidase enzyme that breaks down proteins into peptide molecules. As a digestive enzyme it is located in the lining of the stomach where, relative to the hydrochloric acid in digestive juices, the pH is usually low/ acidic.

Enzymes speed up reaction rates by providing alternative pathways. By modifying the enzyme composition, supplying more collision energy, and changing the collisions between and the ratio of reactants, certain variables will increase the reaction rate.

Proteases function well at 37℃, the typical internal temperature of the human body- this temperature provides adequate energy for the reaction. Similarly, proteases require low pH for the correct configuration, and beyond this pH and temperature, they may become denatured or simply not function well as catalysts.
