Textbook Question
Chapter 17.3, Problem 2CSC
One possible explanation for the distinctive collection of species found in the Annamite and Andes Mountains lies in the geological history of these regions. During the ice ages that have occurred repeatedly during the past million years or so, the area covered by tropical forests must have shrunk dramatically. Organisms that depended on the forests for survival would have been restricted to any remaining “islands” of forest, isolated from their fellows in other, distant patches of forest. As we have learned, this kind of isolation can set the stage for allopatric

13. Practice Calculations: 3 colonies were suspended in the following dilution series and then a
viable plate count and microscope count was performed. Calculate IDF's, TDF's and then
calculate the CFU/mL in each tube by both methods. Finally calculate the cells in 1 colony by
both methods. Show all of your calculations in the space provided on the following pages.

Your first task though is to convince yourself that is true. The best way to do that is to start close to home. Find something in your house that is a product obtained directly from an invertebrate or only due to an invertebrate’s actions. Describe the product, its function and utility, as well as any human manufactured alternatives. Be sure to highlight the advantages of obtaining this directly from nature. Keep in mind, a product can be something you use, wear, eat, or enjoy for its visual appeal.arrow_forward
