Answer:
Explanation:
They need to have sunlight and carbon dioxide in order to produce glucose and oxygen
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).
<span>Foreshadowing means B. hinting at things that will occur later. Sometimes authors may introduce a symbol or a character so as to show the readers that something awaits them in the following chapters, but he or she will not reveal immediately what that actually is. The other examples don't really make any sense and do not refer to what foreshadowing actually is.</span>
