Bonjour,
1. Arteries carry blood from the heart to the rest of the body, whereas veins carry blood from the rest of the body back to the heart.
2. Almost all arteries carry oxygenated blood and almost all veins carry deoxygenated blood.
3. Arteries have a thick elastic muscle layer, whereas the muscle layer for veins is much thinner.
Uranium-235 is the answer
At the point when the wind transports silt by saltation, little particles are brought about to "bob" or "bounce" by the wind, moving them toward the path the wind is blowing. Essentially, the particles are skiped along the surface once or a few times until they lose energy and additionally lift from the twist, and soon thereafter they rejoin the silt on the ground. It is a type of transport that for the most part prepares little particles, however the size increments with expanded wind speed.
Ions are formed when an atom gains or lose electron during a chemical reaction.
<h3>How ions are formed?</h3>
Ions are formed by the addition of electrons or the removal of electrons from an atoms or molecules by the combination of ions with other particles. Ions formation occurs during covalent bond formation and ionic bond formation between different molecules. Those substances that gains electron bears positive ion while on the other hand, those elements that lose electron forms negative ion or charge on the atom.
So we can conclude that ions are formed when an atom gains or lose electron during a chemical reaction.
