1. A friend is concerned because her doctor told her she would be more likely to lose weight by eating regularly and not skipping meals. However, when she eats breakfast, she is always hungry long before lunchtime, when she skips breakfast; sometimes she is not even hungry for lunch. You have just learned that skipping a meal slows the body’s metabolic rate. If metabolic rate is slowed, weight loss is slowed. Therefore, you tell her that she is more likely to lose weight by eating four to six small healthy meals a day instead of eating only one large meal. In other words, each time your friend skips a meal (stimulus), the metabolic rate slows down (response), and the individual is less hungry (stimulus is magnified). This case study exemplifies homeostasis by:
b. Negative feedback
d. Positive feedback.
2. Which statement below best supports the theory that all human cells contain a nucleus?
a. The genetic code (DNA) is stored in the nucleus.
b. Centrioles required for DNA cell division are stored in the nucleus.

d. Cellular division and growth occurs in the nucleus.
3. Which answer below lists the four main tissue types in the human body?
a. Squamous, columnar, stratified, cuboidal
b. Connective, adipose, epithelial, glandular
c. Connective, adipose, epithelial, nervous
d. Epithelial, connective, muscle, nervous
4. Which one of the statements below best describes the difference between the nervous system and the endocrine system?
a. The endocrine system produces changes in the body’s internal environment that are long-term, while the nervous system produces more short-term changes.
b. The nervous system is involved in the regulation and coordination of the body’s internal environment, while the endocrine system is not
c. The nervous system is composed of ductless glands whose secretions regulate the cellular activities of other organ systems.

_________ are part of the efferent division.
a. Sensory neurons; interneurons
b. Interneurons; motor neurons
c. Sensory neurons; motor neurons
d. Motor neurons; sensory neurons
10. The ____________ lobe of the brain is the center of visual association; the __________ lobe is responsible for auditory association; the ___________ lobe controls sensory association; and the ________ lobe maintains motor association.
a. Frontal; temporal; parietal; occipital
b. Frontal; parietal; temporal; occipital
c. Occipital; temporal; parietal; frontal

4. The normal heartbeat is precisely regulated by the electrical impulses generated
From the heart’s conducting cells. The precision of these electrical impulses ensures that blood flows through the heart in the right direction, at the proper time. Which answer below accurately describes the proper sequence of the electrical impulses and the proper direction of blood flow through the heart?

b. Blood enters the right atrium from the inferior vena cava; the SA node ‘fires,” causing contraction of the right ventricle; blood is then pushed into the left atrium; the AV node “fires” causing contraction of the left atrium blood flows into the left
c. Blood simultaneously enters the right atrium from the inferior vena cava, and the left atrium from the pulmonary veins; the SA node “fires,” causing simultaneous contraction of both atria blood flows into the right and left ventricles.
d. Blood simultaneously enters the right atrium from the inferior vena cava and the left atrium from the aorta; the AV node “fires, “causing simultaneous atrial contraction blood enters the right and left ventricles simultaneously the SA node.
