Answer:
Atoms come together to form molecules because of their electrons. Electrons can join (or bond) atoms together in two main ways. When two atoms share electrons between them, they are locked together (bonded) by that sharing. These are called covalent bonds.
Explanation:
Heating up, mostly. Solid can be heated to liquid, then to gas, then eventually to plasma.
In short, I’d say the answer is C.
In solids, the intermolecular force of attraction is very high. Whereas, in liquids the intermolecular force of attraction is somewhat less than solids. ... so when you heat, less amount of heat can free the molecules in liquids than solids and hence they heat faster.
Answer:
The correct answer is A) circulatory
Explanation:
The circulatory system collects metabolic wastes from the blood, which will be eliminated by the kidneys through urine.
The kidneys are responsible for the elimination of waste, acids and excess fluid from the body, maintaining the balance of water, salts and minerals. Blood flows into the kidney through the renal artery.
Water is called a "universal solvent' due to its ability to dissolve many substances. It can dissolve almost all substances. For every substance, water takes its own time to dissolve it. This is due to the polarity present in it.
