Riding a bicycle requires balance and constant adjustment and monitoring by the rider in order to continue cycling. Successfully riding a bicycle most directly results from the ability to

•  sexually reproduce
•  grow and develop
• detect and respond to change
•  metabolize food for energy

 The first successful transplant of insulin producing cells from a living donor pancreas was completed in April 2000 in Japan. This enabled the body of the recipient to

• regulate fat concentration by a feedback mechanism
• provide protection against an infectious disease
•  slow down the heart rate after a period of activity ends
•  maintain blood sugar levels throughout the day

Which statement explains the importance of maintaining a constant internal environment to ensure proper enzyme functioning?

•  Changes in pH and temperature will cause the enzyme reaction rate to be too fast.
• Temperature and pH determine amino acid sequences in enzymes
• Changes in pH will change the genetic instructions of enzymes
• Increasing the temperature and pH can alter the specific shape of enzymes.

Hospital patients are often given intravenous fluids (IVs) to maintain proper levels of water and salts in the body. Great care is used in preparing these solutions. If a manufacturer accidentally prepared a batch of IV fluid that contained much more than the usual amount of salt, harm to the patient could result. The most likely effect on a patient if this incorrectly prepared IV fluid was used is that

• water would move into body cells and cause them to burst
•  water would move out of body cells and cause them to dehydrate
•  salt and water would both move out of body cells and disrupt homeostasis
• salt and water would both move into body cells and preserve homeostasis
