<span>Asbestos is a naturally occurring mineral that has had many commercial uses
</span><span>during the last century, so it can be found in many building materials and other
</span><span>objects. Excessive exposure through inhalation can result in asbestosis, lung
</span><span>cancer, or mesothelioma (another kind of cancer). Asbestos seems to produce
</span><span>cancer through the physical interaction of its fibrous structure with living
</span>cells. Radon is a naturally occurring radioactive gas with no significant commercial application. Excessive exposure through inhalation can result in lung cancer. Radon produces cancer because it emits ionizing radiation which in turn <span>produces cancer upon sufficient exposure.</span>
Answer:
<em>The shape of a cell can easily be seen through a light microscope.</em>
Explanation:
A microscope can be defined as a device which is used to visualize things which are otherwise not visible to the naked eye. The shape of a cell can be seen even through a light microscope. For example, an animal cell can be seen to have a round shape under the light microscope, a plant cell will be seen rectangular under the light microscope.
Other microscopes such as the electron microscope can even show the organelles present inside the cell.

Explanation:
Answer:
Observations; control.
Explanation:
A hypothesis is considered to be tentative or an educated guess and can be defined as a testable explanation for an observation or a scientific problem. An example of a hypothesis is saying, Corona virus is caused by the introduction of the "5G" technology.
On the other hand, a control experiment can be defined as an experiment in which a condition assumed to be a probable cause of the effect is being compared to the same situation by the scientist without involving or using the suspected condition.
Hence, science rejects any hypothesis not supported by observations and the results of control experiments.
<em>This ultimately implies that, for any hypothesis to be acceptable in science, it must be supported by observations and the results of control experiments; this give rise to factual informations, theories and by extension solutions to problems.</em>
