Suppose you have an X ray of an arm, which is taken because the doctor suspects a bone is broken. You also have a drawing showin
Vesnalui [34]

Answer:

An X-ray is done to diagnose the position of bones in the body whether its broken or not or in right place or not.

An X-ray machine is turned on to provide a visual of the bones showing bone condition. When the machine is turned on, X-ray travel through the body tissues, and due to the presence of calcium in bones, they absorb more X-rays, thus bones appear white against the black background of a radiograph.

These white bones on the radiograph will show the position of bones whether it's broken or not.

So, both the visuals that is X-ray and drawing showing visuals (the bones appear white) contribute valuable data to the given situation.

The diagram represents the ____________ formula of glucose.
defon
The answer is D) Structural

That is because we can automatically cross A out, and B is not the answer because ionic compounds aren't polyatomic. Poly atomic atoms are covalent and have no charge. While on the other hand, ions have a charge.
Also, C is not the answer because the molecular formula for glucose is <span>C6H12O6, that leaves us with choice D.
</span>
I can pretty much conclude that D is the answer because you can see that the picture, it has a structure for the compound. Its showing us how the atoms are bonded and structured.
