1.__________________ A pH of 1.0 indicates a strongly basic solution.
2.__________________ Water is a polar covalent compound.
3.__________________ The atomic number of oxygen is 8. Thus, oxygen always contains 8 neutrons.
4._________________ A compound must contain hydrogen to be considered an organic compound.
5.__________________ The closest thing to a universal solvent is water.
6.__________________ Polar molecules are generally soluble in water.
7.__________________The universal energy currency of living cells is RNA.
8.__________________The external fuel of choice used by cells as a ready source of energy is protein.
9._________________Enzymes are almost always lipids.
10._________________The substances on which enzymes act are called cofactors.
11.________________The name of an enzyme usually ends in the suffix –ide.
12._________________Coenzymes are often vitamins that assist the chemical action of enzymes.
13.________________Steroids are a form of lipid that can be used by the body to make some kind of hormones.
14.________________Greater amounts of the pigment carotene are produced when the skin is exposed to the sun.
15.________________The younger epidermal cells in the epidermis are found in the stratum cornieum.
16.________________If tissue damage is very severe, tissue repair is more likely to occur by regeneration, or scarring.
17.________________The term arthritis means that bones ends are forced out of their normal positions in the bone cavity.
18._______________In a sprain, the ligaments reinforcing a joint are excessively stretched or torn.
19._______________Erosion of articular cartilage and formation of painful bony spurs are characteristics of gouty arthritis.
20.________________Healing of a partially torn ligament is slow because its hundreds of fibrous strands are poorly aligned.
21.________________High levels of uric acid in the blood may lead to rheumatoid arthritis.
22._______________A “soft” bone condition in children, usually due to a lack of calcium and/or Vitamin D in the diet, is called osteoporosis.
23.____________Cortical areas involved in hearing are found in the occipital lobe of the brain.
24._____________The left cerebral hemisphere receives sensory input from the right side of the body.
25._____________Damage to the thalamus impairs consciousness and the awake/sleep cycles.
26._____________A flat EEG is evidence of clinical death.
27._____________When blood becomes too acidic or too basic, both the respiratory system and the liver may be called into action to restore it to its normal pH range.
28._____________The normal pH range of blood is 7.00 to 7.45.
29._____________An abnormal decrease in the number of white blood cells is called leukocytosis.
30.________________An anemia resulting from a decreased RBC number causes the blood to become more viscous.
31._______________Phagocytic agranular WBC’s are eosinophils.
32._______________In an emergency, it is probably all right to give a blood type A person blood from a donor who is blood type B.
33._______________The leukocytes particularly important in the immune response are neutrophils.
34._______________The resting heart rate is fastest in adult life.
35._______________If the left side of the heart fails, pulmonary congestion occurs.
36._______________In central congestion, the feet, ankles, and fingers become edematous.
37._______________Renin, released by the kidneys, causes a decrease in blood pressure.
38._______________Two body organs in which vasoconstriction rarely occurs are the heart and the kidneys.
39.______________A sphygmomanometer is used to take the apical pulse.
40.______________The pulmonary circulation is a high-pressure circulation.
41.______________Cold has a vasodilating effect.
42.______________ Thrombophlebitis is called the silent killer.
