Explanation:
Introduction. The tendency to maintain a stable, relatively constant internal environment is called homeostasis. The body maintains homeostasis for many factors in addition to temperature. For instance, the concentration of various ions in your blood must be kept steady, along with pH and the concentration of glucose.

Answer:
B. Shortens
Explanation:
Myofibrils are components of the animal skeletal muscles that are made up of sacromeres. They perform the muscular contraction and relaxation via the sliding filament model.
To produce motion, A cross-bridge forms between actin and the myosin heads triggering shortening of the sacromere. This shortening of the sacromere results in the contraction of the muscle fibers, which the net effect can be seen to be a shortening of the fibers

Answers: 
D) According to the graph, obesity and diabetes are intertwined, which could be why obesity and diabetes are linked. 
E) Diabetes had the greatest rise in prevalence in 1997 until 2000, with prevalence percentages between about 76% to 78%.
Explanation: Explanation for these answers are below:
D) Looking at the graph, obesity and diabetes had similar prevalences in 1997 and 1998, and started to part ways a little in 1999.  In fact, even without the graph, scientists have known for a long time that people who have obesity also have diabetes.  This graph supports that claim because of how closely linked diabetes and obesity are and how similar the prevalence percentages are.
E) Diabetes had the greatest rise in 1997 to 2000, which had a 78% prevalence by 2000.  Obesity had very similar prevalence percentages from 75.5% to 77% in 1997 to 2000.
