Textbook Question
Chapter 39, Problem 5A
You have come up with a brilliant idea to stretch your grocery budget by buying green fruit in bulk and then storing it in a bag that you have blown up like a balloon. As you need fruit, you would take it out of the bag, and it would miraculously ripen. How would this work?
a. The bag would block light from reaching the fruit, so it would not ripen.
b. The bag would keep the fruit cool, so it would not ripen.
c. The high CO2 levels in the bag would prevent ripening.
d. The high O2 levels in the bag would prevent ripening.

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
