Homeostasis can best be described as:

a constant state maintained by living and nonliving organisms. a state of relative constancy. adaptation to the external environment. changes in body temperature.

A structural lipid found in the cell membrane is a:

triglyceride. phospholipid. steroid. Both B and C are correct.

Which of the following is not true of both triglycerides and phospholipids?

They both contain glycerol. They both contain fatty acids. They both contain a hydrophobic and hydrophilic end. All of the above are true of both triglycerides and phospholipids.

lipids. electrolytes. carbohydrates. proteins.

Which of the following vitamins is(are) absorbed through the skin?

Vitamin A Vitamin D Vitamin K All of the above

Which type of muscle is responsible for peristalsis?

Multiunit smooth Single-unit smooth Cardiac Striated

The chief function of the T-tubules is to:

provide nutrients to the muscle fiber. allow for the fiber to contract. allow for electrical signals to move deeper into the cell. allow for the generation of new muscle fibers.

The type of movement possible at a synovial joint depends on the:

amount of synovial fluid in the joint. shape of the articulating surfaces of the bones. presence of bursae in the joint. Both A and B are correct.

All of the following are characteristics of smooth muscle except:

there are no striations. there are no T-tubules. thin and thick filaments are aligned in sarcomeres like skeletal muscles. the sarcoplasmic reticula are loosely organized.

Which of the following is an incorrect statement regarding heat production?

The body temperature set point is established by the hypothalamus. Shivering will increase body temperature. Body temperature functions on a negative-feedback mechanism. All of the above are correct.
