Which factor is NOT considered an environmental factor in chemistry?

Parental genetics is not considered an environmental factor in chemistry because it pertains to the inherited traits and biological makeup of organisms, which are determined by their genetic material. Environmental factors, on the other hand, refer to external conditions that influence the behavior, growth, and development of living organisms and chemical systems.

In chemistry, temperature plays a significant role in influencing reaction rates and the states of matter. Humidity can affect the solubility of substances and the rates of certain chemical reactions, particularly in solutions. Pollution, similarly, can impact chemical processes and interactions in the environment, making it a relevant environmental factor in chemistry. These factors are all external influences that can alter chemical behavior, whereas parental genetics focuses on intrinsic biological characteristics.
