Answer with Explanation:
1. An "x-ray image" shows the difference between the bones and soft tissues because the <em>bones appear white in color </em>while the <em>soft tissues appear gray in color. </em>
2. The reason behind the difference in the appearance of bones and soft tissues on the x-ray film is their<em> density.</em> <u><em>Bones are denser than soft tissues</em></u>, which means that<em> its atoms are closely-knitted when compared to the soft tissues that are far apart from each other. </em>This allows the<em> </em><em>x-ray radiation to be absorbed by the bone </em>while <em>it passes through most of the soft tissues.</em>
This is the reason why pregnant women are advised not to undergo an x-ray examination because<u><em> the fetus is denser and it will surely absorb the x-ray radiation.</em></u>

Answer:
B
Explanation:
In order for any conduction to take place it needs to go through a solid. Therefore it cannot travel through empty space
A volumetric flask is used to contain a predetermined volume of substance and only measures that volume, for example 250 ml.
Conical flasks can be used to measure the volume of substances but the accuracy they provide is usually up to 10ml. Conical flasks are used in titrations, reactions where the liquid may boil, and reactions which involve stirring.
Pippettes are of two types, volumetric and graduated. Pippettes are used where high accuracy is required and volumetric pippettes come in as little as 1 ml. Pippettes are usually used in titrations.
Graduated cylinders come in a wide variety of sizes and their accuracy can be down to as much as 1 ml. They are used to contain liquids.
