TEKS 8.10C explore how short- and long-term environmental changes affect organisms and traits in subsequent populations Readiness Standard In this diagram, a hawk is hunting for mice in a field. Some mice are white while others are dark. 1. An organism with traits will survive and passing those traits to the next 2. Which population of mice is naturally selected to survive? 3. What will happen to the white mice population? 4. What will happen to the dark mice population? 5. If a drought occurred and made the environment above lighter in color due to less vegetation, what would happen to both populations of mice?

Q6.2. If there is NO SELECTIVE SURVIVAL based on shell thickness within a population of snails, what happens to shell thickness in response to crab predation? O The average shell thickness increases within each generation, but there is no change in shell thickness from generation to generation. O There is evolution by natural selection of shell thickness, and average shell thickness increases every generation. O There may be evolution of shell thickness, but not through natural selection and not necessarily toward thicker shells. O There is no change in shell thickness within the population.
