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 .

If I'm not mistaking herbivores are primary consumers
Answer:
The correct option is: c. a doorknob contaminated with the cold virus
Explanation:
Fomites are the inanimate objects or substances that can get contaminated with the pathogens and are capable of transferring the pathogens to the new hosts.
Sterilization of the possible fomites should be done in order to prevent cross-infection.
Examples of fomites are hair, towels, clothes, door knobs, cups, switches, handrails, remote controls, pens, syringes, bedding, etc.
