Answer to Question 1

C, B, E, A, D
Feedback:
The error theory of aging proposes that DNA mutations occur on a single-cell level and are perpetuated in subsequent cell divisions. The overall number of mutant cells in the body increases and causes deleterious effects on tissues and systems and eventual decline in body function.

Answer to Question 2

B
Keloids, which originate in scars, are hard and shiny and are seen more often in African Americans than Caucasians.

Early clockmakers apparently thought that the IIII balanced out the VIII (used for the number 8) on the clock face and that it just looked better.
