The change that would decrease the pH of a base in a solution at equilibrium is : ( C ) Decreasing the concentration of OH⁻ ions
A base in a solution provides ( OH⁻ ions ) while an acids produces H⁺ ions. therefore an acidic solution ( solution with a lower pH level ) has more H⁺ ions and a decrease in OH⁻ will lead to a corresponding increase in H⁺ ions. so when the concentration of OH⁻ ions is reduced the pH of the base in the solution will be reduced
Hence we can conclude that in order to decrease the pH of a base in a solution at equilibrium decreasing the concentration of OH⁻ ions will help decrease the pH level of the base .

Reclamation of sanitary landfills occurs before the land fills is capped.
Explanation:
Reclamation of sanitary landfills is a method use to expand the municipal solid wastes sanitary landfill capacity so as to avoid high cost of purchasing another land.
Sanitary landfills is an area of land where wastes is allow to decompose or degraded chemically, physically and biologically until it is safe.
This reclamation is done before the landfills is capped so as to avoid high cost of getting another land.
He must record and describe characteristics of that beetle
He then can compare this beetle with others to make sure it is actually a new species
Of the possible types of relationships - parasitism is the only one which doesn't really represent a symbiotic type of a relationship. All of the other ones here (mutualism, commensalism and competitive exclusion) are some form of symbiotic relationship.
