These are genetic characteristics that allow an organism to withstand conditions or substances that would typically harm or kill it.
Think about waterproof watches. They have specific traits (like rubber seals) that make them resistant against water damage. Similarly, organisms with resistant traits have special features in their DNA which help them survive harmful conditions or substances.
Genetic Variation: Differences in genes among individuals within a population.
Natural Selection: The process where organisms better adapted to their environment tend to survive and produce more offspring.
Adaptation: A change or the process of change by which an organism becomes better suited to its environment.
