Answer:
An enzyme can be described as a biological molecule which catalyzes a reaction. Each organism works best at an optimum temperature and pH.
If the pH is too high or too low than the optimum pH, then the enzyme such as enolase will become denatured and it will not be able to catalyze the reaction.
A change in pH causes the enzyme the shape of an enzyme to get changed or it changes the specific charge properties of the substrate of that enzyme. As a result, the substrate is no longer able to fit into the active site of the enzyme. Hence, the enzyme is not able to catalyze the reaction.
Gases are less dense than solids. this is because, since density refers to how close the particles are together, in gases, there is more space for the particles to move, making it less dense than solids.

Answer:
Innate; adaptive
Explanation:
Immunity is the ability of an organism immune system to provide protection against pathogens. The immune system comprises of Innate and adaptive immune system.
The innate immune system is non-specific immune response to foreign substance and it comprises of physical barriers such as skin, chemicals and immune cells.
Adaptive immune response is specific immune response to particular antigen. It comprises mainly of T and B cells. In adaptive immune response the antibodies are produced and memory is created in exposure to specific antigen. So when next time that foreign antigen enters the body, it will produce the same specific immune response because of memory.
