Explain why your results of the optimal temperature of the lactase enzyme make sense for the human enzyme

Because the human body is below 40degrees Celsius which is the optimal temperature of the lactace enzyme.

At the optimal or average body temperature of the body the human body, the nature of the lactase protein is not denatured.

Explanation: Lactase enzyme is produced in the cells of the small intestine of humans and most mammals,the main function of the Lactase enzyme is to ensure the digestion of sugars that are present in the milk and other dairy products consumed by both humans and other mammals.

The optimal temperature of the lactase enzyme is 40degrees Celsius which means it can successfully fulfill and perform its functions within the human body whose temperature is generally below 40degrees Celsius.

option a is correct i.e.

explanation:

in context to the membrane of nerve impulse, the outer membrane of neuron is semi permeable that is only sodium ions can pass through the membrane i.e. smaller ions can pass through the membrane while larger ions cannot pass through it.

the relative atomic mass of an element is the mass of one atom of that element, relative to 1/12th of the mass of a  1212c atom. to convert to an absolute mass in kg, it is necessary to multiply by  1.661×10−271.661×10−27.

the relative atomic mass is roughly equal to the number of neutrons, plus the number of protons, in the nucleus of the atom.

for elements with more than one stable isotope (different types of nucleus with different numbers of neutrons but the same number of protons), the quoted mass is usually the average mass, weighted by the relative abundance of the different isotopes.
