Answer to Question 1

False

Answer to Question 2

There are several possible answers that students may provide, but the major theories covered in the textbook are as follows:

(a) Programmed theories suggest that we are born with a biologically or genetically predetermined program for how we will age, including how long we will live.

(b) Wear-and-tear theory suggests that the body, much like any machine, gradually deteriorates and eventually wears out.

(c) Free radical theory some researchers suggest that normal cell metabolism can produce chemicals that bond to and disrupt other substances inside cells. This, in turn, can lead to cellular damage and impaired functioning.

(d) Cross-linking theory suggests that there are some proteins that randomly interact with certain body tissues, such as muscles and arteries

(e) Cellular theories explain aging by focusing on processes that occur within individual cells, which may lead to the buildup of harmful substances or the deterioration of cells over a lifetime.
