Question

1. how do environmental changes lead to adaptations over generations?

Explanation:

Environmental changes create selective pressures. Organisms with traits better suited to the new environment have higher survival and reproduction rates. These advantageous traits are passed on to offspring. Over generations, the proportion of individuals with these adaptive traits increases in the population.

Answer:

Environmental changes lead to adaptations over generations through natural selection. When the environment changes, organisms with traits that help them survive and reproduce in the new conditions are more likely to pass those traits to their offspring. Over time, the population evolves to be better adapted to the changed environment.
