Increasing the concentration of substances in a chemical reaction will
increase reaction rate
decrease reaction rate
have no effect on reaction rate

Option (a) is the correct answer.

Explanation:

When we increase the concentration of substances in a chemical reaction then it means there are more number of molecules present in a reaction.

Hence, when these molecules will interact with each other then there will occur more number of collisions. As a result, kinetic energy of molecules will increase and this leads to increase in rate of chemical reaction.

Thus, we can conclude that increasing the concentration of substances in a chemical reaction will increase reaction rate.

poor water quality affects most estuarine organisms, including commercially important fish and shellfish. the pollutants that have the greatest impact on the health of estuaries include toxic substances like chemicals and heavy metals, nutrient pollution (or eutrophication), and pathogens such as bacteria or viruses.

i would say that hybridization occurs frequently in nature, because there are many types of hybrids that have occurred naturally, such as the mule (male donkey + female horse)
