10. Question 5 – 3 points  Why would the roots of desert plants most likely be deeper than the roots of most plants found in the tropical rain forest?

11. Question 5 – 3 points  Why would the roots of desert plants most likely be deeper than the roots of most plants found in the tropical rain forest? - In a rain forest, there is plenty of water available, roots don’t need to grow very deep. OR - In a desert, there is less available water, so roots grow deeper to collect the available water.

22. Question 11 – 4 points  What is the basic difference between natural selection and selective breeding?

23. Question 11 – 4 points  What is the basic difference between natural selection and selective breeding?  Natural selection is a process that occurs in the wild. Changes occur because of environmental influences.  Selective breeding is an artificial, man-made process where humans select the traits that are most desired for our purposes.

27. Question 13 – 4 points  Explain why the many species of Galapagos Islands finches have so many different types of beaks.  Each of the finches have specialized in consuming different available food, requiring different beaks that had to change slowly over many generations.

28. Question 14 – 3 points  What is the process that occurs when species that are most suited to their environment survive and get to pass on their successful traits to their offspring?

29. Question 14 – 3 points  What is the process that occurs when species that are most suited to their environment survive and get to pass on their successful traits to their offspring?  Natural Selection

30. Question 15 – 3 points  Xylem is an adaptation that allows water to travel against gravity up to the top of plants from their roots. What does this adaptation allow plants to do? (Hint: Plants compete for sunlight)

31. Question 15 – 3 points  Xylem is an adaptation that allows water to travel against gravity up to the top of plants from their roots. What does this adaptation allow plants to do? (Hint: Plants compete for sunlight)  Xylem allows plants to grow taller, thus possibly reaching more light than their competition.

32. Question 16 – 3 points  There are behavioral traits that are also important adaptations that help a species survive. If a specie lives in an area that faces increasingly colder weather every year, what would a likely behavioral adaption be?
