  2. QUESTION: Review Which of the following is NOT a part of the process of natural selection? a) Organisms struggle to survive. b) Organisms limit the number of young they produce. c) Individuals vary in their genetic characteristics. d) Some individuals are better suited to their environment than others.

  3. QUESTION: Review Which of the following is NOT a part of the process of natural selection? a) Organisms struggle to survive. b) Organisms limit the number of young they produce. c) Individuals vary in their genetic characteristics. d) Some individuals are better suited to their environment than others.

  4. QUESTION: Review Disruptive selection would result in which of the following? a) Dogs with black coats evolving whiter coats in colder areas b) Red and white flowers interbreeding, producing pink flowers c) Fish evolving bigger eyes as the water gets muddier d) A population of birds, some with thicker beaks, that eat seeds; and others with thinner beaks that eat insects

  8. QUESTION: Review Sympatric speciation would occur in: a) One population that mates in May, and another that mates in June b) Two populations separated by the Mississippi River c) Two populations separated by a glacier d) Two populations separated by the Rocky Mountains

  10. QUESTION: Review Which of these species is least vulnerable to extinction? a) A species with a population size of 50 individuals b) A species distributed throughout the UnitedStates c) A species that eats only river snails d)A species that lives on mountaintops

  11. QUESTION: Review Which of these species is least vulnerable to extinction? a) A species with a population size of 50 individuals b) A species distributed throughout the United States c) A species that eats only river snails d)A species that lives on mountaintops

  12. QUESTION: Review An ecosystem is defined as: a) The total living things on Earth b) Members of the same population that can interbreed c) Interacting species in an area d) Species and the nonliving material they interactwith

  13. QUESTION: Review An ecosystem is defined as: a) The total living things on Earth b) Members of the same population that can interbreed c) Interacting species in an area d) Species and the nonliving material they interactwith

  14. QUESTION: Viewpoints Should we care whether a species goes extinct? • Yes, because all life is important and valuable. • Yes, because we are causing this wave of extinction, so we should fix it. • We should not, because it’s natural. • I don’t care; it really does not affect me.

  15. QUESTION: Viewpoints Should we care whether a species goes extinct? Yes, because all life is important and valuable. Yes, because we are causing this wave of extinction, so we should fix it. We should not, because it’s natural. I don’t care; it really does not affect me.

  16. QUESTION: Weighing the Issues Do you think humans are subject to limiting factors and, ultimately, a fixed carrying capacity? • Yes, although we have raised the carrying capacity, there are limits to the number of humans Earth can support. • Yes, but technology will keep raising the carrying capacity, so it’s not much of a problem. • No, humans are no longer constrained by environmental limits, due to our technology and ability to manipulate the environment. • I don’t care; it really does not affect me.

QUESTION: Weighing the Issues Do you think humans are subject to limiting factors and, ultimately, a fixed carrying capacity? • Yes, although we have raised the carrying capacity, there are limits to the number of humans Earth can support. • Yes, but technology will keep raising the carrying capacity, so it’s not much of a problem. • No, humans are no longer constrained by environmental limits, due to our technology and ability to manipulate the environment. • I don’t care; it really does not affect me.
