Answer:
everything about cells
Explanation:
you told me to tell you that, and this answer is reasonable
but if you want you can write everything about cells on your test or homework and say you were too tired, sleepy, exhausted, and utterly brainwrecked.
Answer:
This means that some cells are able to letter molecules pass through them and this makes it easier for the molecules to pass through.
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).
