Textbook Question
Chapter 46, Problem 1A
You take X-rays of two individuals. Ray has been a weight lifter and body builder for 30 years; Ben has led a mostly sedentary life. What differences would you expect in their X-rays?
a. No difference, they would both have thicker bones than a younger person due to natural thickening with age.
b. No difference, lifestyle does not affect bone density.
c. Ray would have thicker bones due to reshaping as a result of physical stress.
d. Ben would have thicker bones because bone accumulates like fat tissue from a sedentary lifestyle.

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
