Any prevention/promotion innovation has certain elements that are central to its effectiveness and must be included in any implementation, and other elements that can be modified to fit the context of a new setting. These are termed:

adaptive components

Explanation:

adaptive components describe or refers to adapting elements or functional parts from successful innovations in such a way that it fits the context of the new implementation and doesn't entirely copy the other one. Here components are collected and used to create better functional products, drawing from parts of already successful products that have shown good results.

core components and adaptive components respectively.

Explanation: Core and adaptive components are essential to prevention or promotion innovation. The core components are the most essential parts of the innovation process that are central to the effectiveness of the process and must be included in any implementation while the adaptive components can be modified to fit the context of a new setting.

It is important to distinguish between core and adaptive components because while adaptive components can be modified to fit the specifics of the setting, core components must be implemented with utmost fidelity in order to ensure the effectiveness and functionality of the innovation program.

question - in 1827, john walker, a druggist in a small english town, tipped a splint with sulphur, chlorate of potash, and sulphid of antimony, and rubbed it on sandpaper, and it burst into flame. the druggist had discovered the first friction-chemical match, the kind we use to-day. it is called friction-chemical because it is made by mixing certain chemicals together and rubbing them. although walker's match did not require the bottle of acid, nevertheless it was not a good one. it could be lighted only by hard rubbing, and it sputtered and threw fire in all directions. in a few years, however, phosphorus was substituted on the tip for antimony, and the change worked wonders. the match could now be lighted with very little rubbing, and it was no longer necessary to have sandpaper upon which to rub it. it would ignite when rubbed on any dry surface, and there was no longer any sputtering. this was the phosphorus match, the match with which we are so familiar. according the paragraph what was the benefit of the new phosphorus match? it burst into flame when rubbed on sandpaper. it was made by mixing chemicals. it could be ignited on any dry surface. it threw fire in all directions.

answer - matches required natural chemicals
