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:
All matter is made up of tiny particles called <em><u>a</u></em><em><u>t</u></em><em><u>o</u></em><em><u>m</u></em><em><u>s</u></em><em><u>.</u></em> Atoms are made up of three subatomic particles known as <em><u>proton</u></em><em><u>,</u></em><em><u> </u></em><em><u>neutron</u></em><u> </u>and<em><u> </u></em><em><u>electron</u></em><em><u>.</u></em> Protons and neutrons are located in the <em><u>nucleus</u></em><em><u>.</u></em>
The nucleus is dense and takes up very little space within the atom. All protons have a <em><u>positive</u></em><em><u> </u></em>charge and have a mass of about 1 amu. All neutrons have no charge or are <em><u>neutral</u></em> and have a mass of about 1 amu.
Electrons are located in the area known as electron cloud. Electrons orbit around the nucleus and have a <em><u>negative</u></em> charge

Explanation:
Answer: De câte cărămizi am nevoie? Pentru un perete de cărămidă cu strat singular, înmulțiți lungimea peretelui cu înălțimea pentru a obține zona. Înmulțiți acea zonă cu 60 pentru a obține numărul de cărămizi de care ar trebui să aveți nevoie, apoi adăugați 10% pentru risipă. Acesta este răspunsul scurt și presupune dimensiuni „standard” de cărămidă și mortar.
