Question

recalling the medical tool and equipment terms
use the drop - down menus to complete the sentences.
a biohazard is a form of energy characterized by the passage of particles or waves through a medium. examples include light, heat, radio waves, and x - rays.
a(n) is a form of electromagnetic radiation that can be used for medical imaging and therapeutic purposes.
uses x - rays to create 2 - d and 3 - d images of parts of the body. it is also known as a scan.
(the drop - down options include carcinogen, sharp, x - ray, drug, etc.)

Explanation:

First Sentence (about biohazard and the blank):

The first blank is about a form of electromagnetic radiation used in medical imaging/therapy. From the dropdown, "X - ray" is a form of electromagnetic radiation (along with light, heat, radio waves as examples given). Carcinogen is a cancer - causing agent, sharp is a physical hazard type, drug is a medicinal substance, so X - ray fits here as it's a type of electromagnetic radiation.

The device that uses X - rays to create 2 - D and 3 - D images of the body and is also known as a [blank] scan. "Computed tomography (CT) scan" (from the visible part "comp...phy scan" which is likely "computed tomography") uses X - rays. The other options: carcinogen is not a scan, sharp is not a scan, drug is not a scan, X - ray is the radiation, not the scan device. So the correct term for the scan using X - rays is "computed tomography" (the dropdown option that starts with "comp" is "computed tomography" or "CT" scan, so the blank should be filled with "computed tomography" (or the option from the dropdown, likely "CT" or "computed tomography", but from the visible text "comp...phy scan", it's "computed tomography" scan, so the answer is the option related to that, which is the one with "comp" (computed tomography) in the dropdown.

Answer:

X - ray

Second Sentence (about the device that uses X - rays for imaging):
