LIFE SCIENCE

Detailed explanation-1: -Natural selection is a mechanism of evolution. Organisms that are more adapted to their environment are more likely to survive and pass on the genes that aided their success. This process causes species to change and diverge over time.

Detailed explanation-2: -This variation means that some individuals have traits better suited to the environment than others. Individuals with adaptive traits-traits that give them some advantage-are more likely to survive and reproduce. These individuals then pass the adaptive traits on to their offspring.

Detailed explanation-3: -No organisms change as the population adapts. Rather, this involves changes in the proportion of beneficial traits across multiple generations. 5. The direction in which adaptive change occurs is dependent on the environment.
