The difference between reversible and irreversible is that reversible changes can be changed and irreversible changes cannot. Apart from sometimes but it usually is really hard. Also when the change is reversible no new substances are formed. When the changes are irreversible they are. Something that is reversible can be changed, something that is irreversible cannot be changed. For example, bread into toast is an irreversible reaction, because you cannot turn the toast back into bread.
No. Gingivitis is simply inflammation of the gums. It is the most common oral disease in humans, affecting small children and adults of all ages. It is generally reversible with good oral hygiene (brushing and flossing) and perhaps a dental cleaning at a dental office.
The "mass defect" -- the fact that the mass of an isotope is less that the sum of its nucleons is due to the fact that when nucleons combine (either by fusion, for elements with atomic number less than iron[A=26]; or fission for elements with atomic number greater than iron) there is a release of energy due to the nuclear binding force, which source of the "mass defect" you correctly identified. The energy released as a result of the binding of the nucleons is equivalent to a small amount of mass of the matter -- Einstein's famous equation: E=mc^2, so the energy release E
The reactants in a chemical reaction exist before the reaction begins and are consumed during the reaction. Once the reaction is complete, the reactants are typically no longer present. However, in some cases, a small amount of reactant may remain unreacted or there may be reversible reactions where some reactants can be regenerated.
The moment magnitude scale is used to measure the magnitude of large earthquakes. The Richter scale is still used to make an initial estimate of the magnitude of larger earthquakes and to measure small and moderate ones (those with a magnitude below 7).
This microwave has a fixed door,it is not reversible.
in most there is a small lever on the head. This changes the twist .
of course its irreversible because once you have cooked the popcorn you cannot turn it back into what it was and originally they were small grains of corn
"doping" is intentional, the addition of a small (and usually precisely measured) "impurity" ... for a reason. "defect" just means you did something wrong.
A malformation, break, or hernia of the thoracic vertebrae in the spine.
no internal resistance of a cell cannot be considered to b as a defect because the resistance is so small as compared to the output we get from a cell this ristance can be neglected..

Earthquake intensity is measured using the Modified Mercalli Scale. That is basically a 'subjective' scale (as opposed to the Richter scale, which measures magnitude), because intensity is measured by the impact is is reported to have on people and their property, as reported by them. So a big earthquake like 8 on the Richter scale can have a low intensity if it happens in an area where few people live. A small earthquake can be high-intensity if it happens in a crowded area with many ramshackle houses.
It isn't louder (loudness has to do with intensity, and a small whistle can't generate that much intensity), it's a higher frequency. In the range that is inaudible to humans.

Spina bifida is a congenital defect that occurs when a small part of the spinal cord along with its meninges are exposed.
