After initiating an action potential, there is a period of time called during which a cell cannot generate another ap, no matter how strong the stimulus.
a. relative refractory period
b. absolute refractory period
c. summate refractory period

B. Absolute refractory period

Explanation:

Action potential has a refractory period that divides in two: relative and absolute. Relative refractory period allows the generation of another AP but needs a greater initial despolarization to reach the excitation threshold. Absolute refractory period cannot generate another action potential no matter how strong the stimulus is.

elevated levels of blood glucose (hyperglycemia) lead to spillage of glucose into the urine, hence the term sweet urine.
