So, in that case, a non metallic mineral, (think coal) wouldn’t shine much. A metallic mineral would shine, because it’s metal. And something that’s shiny obviously shines.
Go with A B and C.
<span>The half-life of a radioactive isotope describes the amount of time that it takes half of the isotope in a sample to decay. In the case of radiocarbon dating, the half-life of carbon 14 is 5,730 years. This half life is a relatively small number, which means that carbon 14 dating is not particularly helpful for very recent deaths and deaths more than 50,000 years ago. After 5,730 years, the amount of carbon 14 left in the body is half of the original amount. If the amount of carbon 14 is halved every 5,730 years, it will not take very long to reach an amount that is too small to analyze. When finding the age of an organic organism we need to consider the half-life of carbon 14 as well as the rate of decay, which is –0.693.</span>
If a woman experiencing an asthma attack had taken two puffs
from her prescribed inhaler before my arrival and there was no relief. I would
first administer supplemental oxygen, and I’ll then proceed to contact medical
control for further advice.
Answer: Pathology

Fluid samples collected include blood, urine, semen, and mucus. Other factors tested include temperature, blood pressure, etc. All this helps in accurate diagnosis of the disease.
