Answer:
Nuclear decay rates are constant
Explanation:
Spontaneous decay of unstable nuclei is a process of a statistical nature, it is not possible to predict with certainty when an individual radioactive nucleus will decay, nor can the decay process be influenced in any way.
Therefore, the half-life of radionuclides (specific for each radionuclide) is defined as the time period in which half of the initial number of radioactive nuclei decays.
The unit of measurement for the radioactivity of the material is the becquerel (Bq) and denotes the number of decays in one second (1Bq = 1 decay / 1 second).
Given away by its name, the frontal lobe is located in the front of the brain. The frontal lobe is responsible for emotion, speech, problem solving, and motor function. It is also the largest of the lobes.

c.Chromatin in the nucleus condenses.
Prophase is the 1st stage. So in Prophase chromatin don't condence. It occurs at anaphase.
