For all the circled problems! will mark brainliest

14. No the fire is not alive because it does not contain any cells (think of the characteristics of all living things)

15. It is important to eat a balanced diet because since everything in our body such as organs is cells they need the energy and nutrition to function well, and have maintain and produce pathogen/viral/bacteria fighting cells.

16. The food that you could eat that contains nucleic acids/nucleotides are meat since animal muscle has ATP molecules. Seafood also has this.

it provides an alternative energy pathway for the reaction to proceed.

a catalyst is a substance that speeds up the rate of a chemical reaction but is not consumed during the course of the reaction.

catalysts increase the rate of reaction without being used up. they do this by lowering the activation energy needed. with a catalyst, more collisions result in a reaction, so the rate of reaction increases. different reactions need different catalysts.

a catalyst works by providing an alternative reaction pathway to the reaction product. the rate of the reaction is increased as this alternative route has a lower activation energy than the reaction route not mediated by the catalyst.
