Eating a healthy diet doesnât have to be overly complicated. While some specific foods or nutrients have been shown to have a beneficial effect on mood, itâs your overall dietary pattern that is most important. The cornerstone of a healthy diet pattern should be to replace processed food with real food whenever possible.
Making the world better, one answer at a time. A catalyst is a character tha brings about change in the story. For example, a catalyst's actions could cause one character to lose trust in another, or something of the sorts. Basically, if the story takes a different course because of a certain character, that character would be a catalyst.
A catalyst is a substance that will change the rate of a reaction. A catalyst is often used to make a reaction go faster. The catalyst does not take part in the reaction as a reactant. It is not changed by the reaction or used up during the reaction. It is still there in the same form when the reaction is complete. A catalyst can be a transition metal, a transition metal oxide (see the uses of transition metals) or an enzyme. An exception is aluminium oxide, used for the cracking of hydrocarbons. A substance which works well as a catalyst for one reaction might not work well as a catalyst for a different reaction.
