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).
The correct answer is: subjunctive and conditional.
Subjunctive mood – mood used for the expression of various states of unreality. This include the states such as wish, emotion, possibility, opinion..
Conditional – used for the expression of states: what could happen, what might have happened, and what we wish would happen..
abiotic factors.
An abiotic factor is a non-living part of an ecosystem that shapes its environment.
It is The multicellular part
