Many developing countries exist in an ecological surplus because their population needs do not exceed their land, food, and water resources. Which scenario describes the best way to prevent an ecological deficit for a developing country? Export garbage and wastes to other countries
Import beef and soy products into the country
Slow population growth by regulating birth rates
Start a recycling and waste reduction program

characterization of nanoparticles is a critical step in nanomaterial production as it provides information of dimension, morphology, surface charge, distribution and degree of surface functionalization.

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.
