Answer:
Punctuated Equilibrium
Explanation:
The phyletic gradualism model and the punctuated equilibrium are aspects models of macroevolution that are characterised with varying patterns.
However, the punctuated equilibrium model of evolutionary history consists of geologically long periods of inactivity (stasis) with little or no evolution, interrupted or "punctuated" by geologically short periods of rapid evolution.

Answer:
Buffer
Explanation:
Buffers may be defined as the solution of a weak acid with ithe conjugate base or a weak base with the conjugate acid. Buffers are not affected by the the additions of strong acid or base in a solution.
Whenever a strong base or acid is added to the buffer, it may release or binds with the hydrogen ion and maintains the pH of a body fluid. Blood has a buffer of carbonate ions and bicarbonic acids that maintains the blood pH.
Thus, the correct answer is option (E).
