3 inches per year best represents the average rate at which infants grow in height during the first four years after birth. The correct option among all the options that are given in the question is the second option or option "b". The other choices given in the question seems quiet absurd. So by the method of elimination, one can say that option "b" is correct.

Answer:

The correct answer is option b, that is, 3 inches per year.

Explanation:

Humans seem to develop at a specifically gradual rate unless and until one reaches puberty. The rate of growth could differ on the basis of the genetic composition and nutrition plan of the infants. For example, the Asian babies grow at a gradual rate with 2 to 2.5 inches in a year. The three inches in a year best illustrates the average rate at which the infants grow in height at the time of the initial four years post-birth.

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.
