Answer:
Radioactive isotopes are widely used in medical field
Explanation:
Radioactive isotopes are widely used in medical field.
Radiations emitted by radioactive isotopes or used to kill the microorganism in food and to increase the shelf life of food.
Cobalt-60 is used to treat the cancer.
Iodine-131 is used to check the activity of thyroid.
Technetium-99 also used for the thyroid.
Phosphorus-32 is used to detect the cancer specially in skin and eyes.
Xenon-133 is used for lungs imaging.
Au-198 is used to diagnose the liver disease.
Co-60 is used as gamma ray irradiation of tumor.
In industry radioactive isotopes are used to measure the thickness of materials.

Answer:
<h2>Density = 0.00026 g/mL</h2>
Explanation:
The density of a substance can be found by using the formula
<h3>

</h3>
From the question
mass of air = 1.2 g
volume = 4,555 mL
Substitute the values into the above formula and solve for the density
That's
<h3>

</h3>
= 0.0002634
We have the final answer as
<h3>Density = 0.00026 g/mL</h3>

Let's look at the choices and see why they work, or don't work.
monosaccharide
* Otherwise known as a simple sugar. And NaCl is definitely not a sugar of any type. So this is wrong.
disaccharide
* Complex sugar. And NaCl doesn't qualify either.
organic
* A definition of an organic compound is one that has carbon in it. NaCl has sodium and chlorine. No carbon at all, so this isn't the right answer. And I wish that organic was an earlier choice, since the sugars mentioned above are organic compounds.
inorganic
* This is the only possible choice. Salt is not an organic compound since it doesn't have carbon. So it can't be a sugar either. But it can and is inorganic.</span>
The objects which cannot be observed in detail without a microscope
include the following:
<h3>What is a Microscope?</h3>
A microscope is an instrument which is used to view smaller objects such as
microbe,cells, tissues etc. This instrument is used in viewing the different
cells found in the body as they can't be seen with the eye.
The remaining options which can be seen with the eyes don't require
the use of microscopes.
