A shadow is a surface light cannot touch or reflect off of. Usually shadows appear when the main object is covering a light source. For example, lunar eclipses. Lunar eclipses cause a shadow over Earth because they block the main light source, The Sun from our point of view, casting a giant shadow over Earth.

Nuclear fusion is the combining of atomic nuclei to produce energy and new types of
galben [10]
Im not sure how to answer this since there were no choices given but I will answer by telling you what nuclear fusion is...

so basically nuclear fusion is the merging or combining of 2 isotopes, typically isotopes of hydrogen, under conditions of extreme temperature and pressure thus resulting in the release of massive amounts of energy. I think the answer to your question would be new types of electricity because the heat emitted from the reaction could be turned into electricity by using its steam. This is what happens in nuclear reactors

Victor put a match on a balance and found that its mass was 6.0 grams. Then he lit the match and put it out after a few seconds.
Tcecarenko [31]

Answer: It releases oxygen and heat. The answer is C

Stored inside the match head is another chemical called “potassium chlorate”. When it gets hot, it releases a lot of extra oxygen and heat. This makes the match head burn quickly and strongly. When you put it all together the heat, the fuel, and the oxygen  you get a flame. Matter does not go when something is set on fire. Matter is always the same.  Burning is a chemical process. The flames are caused as a result of a fuel undergoing combustion (burning). (CC BY-SA 2.5; Einar Helland Berger for fire and Walter Siegmund for ash).

What do you think will happen to the ph and pco2 levels with hyperventilation?
umka2103 [35]

It will increase blood pH. This is because pCO2 also reduces. pCO2 is critical in the <span>maintenance of blood pH. Dissolved CO2 from respiring tissues dissolves in blood to form carbonic acid. The carbonic acid partially dissociated into H+ ions and its conjugate base (bicarbonate ions). Carbonic anhydrase catalyzes the formation of carbonic acid (in tissues) and vice versa (in the lungs). In the lungs, the carbon dioxide is expelled.  </span>
