If I am conducting an experiment to check if cells are living and their functionality after putting an organ into solutions with different salt concentration, then what should be the research question and should the data collected be quantitative or qualitative? (The main motive is to check the functionality of cells after they are dispersed in hypotonic, hypertonic and isotonic solution) (And the question is - Why are solutions used to store organs for donation isotonic?)

wha is what i will use to get my free points

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.

protein makes up the building blocks of organs, muscles, skin, hormones and pretty much everything that matters in your body.

some choices are:

peanut butter

seeds

eggs

yogurt

meats

fish

so pretty much meat, dairy, nuts, and grains.
