Which of these statements is true regarding the way light travels? A. Sound travels faster than light. B. The speed of light is always the same regardless of the medium through which it travels. C. Light travels as both a wave and a particle. D. Light can not travel through a vacuum. Correct Answer C. Light travels as both a wave and a particle. Light is a curiosity in that it acts as both a wave and a particle. It only changes direction via reflection (bouncing off of something) or refraction (passing from one medium to another). In a vacuum, the speed of light is constant, but when passing through a medium that has an index of refraction different from a vacuum, light's speed slows. Which of these elements is liquid at room temperature? A. mercury B. zinc C. manganese D. magnesium Correct Answer A. mercury Mercury is the only one of the elements listed here that is liquid at room temperature. The element bromine also has this property. Where is the hyoid bone located? A. neck B. pelvis C. rib cage D. leg Correct Answer A. neck The hyoid bone is located between the chin and thyroid cartilage. A person with AB- blood should not receive blood from which other blood type? A. B- B. A- C. O- D. AB+ Correct Answer D. AB+ Those with an AB- blood type should not receive blood from those with AB+ blood. Although both AB+ and AB- blood have A and B antigens, the person with AB- blood lacks a special protein, or "Rhesus" Factor (Rh), circulating in their blood. If they are

given blood that has the Rh factor present, their body will make antibodies to this foreign substance and complications will occur. This is especially true in pregnancy situations where the mother is Rh- and the baby she is carrying is Rh+. Which blood type is considered the universal donor? A. O- B. O+ C. AB- D. AB+ Correct Answer A. O- O- blood lacks both A and B antigens and the Rh factor, making it the only blood type that can donate to everyone. Note the correct use of the terms antibody and antigen: O- is the best donor because it does not have A, B or Rh antigens. AB+ is the universal receiver because it does not have A, B or Rh antibodies. What is the only artery in the body to carry oxygen-poor blood? A. renal artery B. interosseous artery C. vena cava D. pulmonary artery Correct Answer D. pulmonary artery Most arteries in the body carry oxygen-rich blood away from the heart, but the pulmonary artery carries oxygen-poor blood from the right ventricle of the heart to the lungs. The vena cava would not be correct because it is not an artery, it is a vein and the question asks for an artery. Chocolate cysts of the ovaries are attributed to

. A. menorrhagia B. ectopic pregnancy C. pelvic inflammatory disease D. endometriosis Correct Answer D. endometriosis Endometriosis is a condition in which the tissue from the uterus (endometrium) grows in other parts of the body, such as the ovaries or bowel. If a woman has endometrial tissue in her ovary, the tissue bleeds and builds up over time, and as the blood ages it turns brown, hence the term "chocolate cyst." Which is not true of synovial joints? A. They are found in the intervertebral discs of the spinal column B. They have a fluid-filled capsule that surrounds their articulating surface C. They are the most common joint in the body D.

Prokaryotic cells can contain lysosomes and eukaryotic cells have mitochondria D. Prokaryotic cells have a nucleus Correct Answer B. Eukaryotic cells have mitochondria One of the major differences between eukaryotic cells and prokaryotic cells is that eukaryotic cells contain organelles, such as mitochondria and lysosomes, whereas prokaryotic cells do not. Positive feedback is a mechanism used by the body that results in amplification or enhancement of a signal that has already been activated. An example of this would be . A. the release of oxytocin to increase contractions during childbirth B. shivering to increase temperature C. slowing metabolism in response to starvation D. blood vessels regulating blood pressure Correct Answer A. the release of oxytocin to increase contractions during childbirth Contractions in childbirth are considered a positive feedback loop because each contraction stimulates the brain to release more oxytocin, which in turn stimulates more contractions. When placed in a hypotonic solution, what will a cell do? A. shrink B. swell C. disintegrate D. remain the same Correct Answer B. swell Water always moves from areas of higher concentration to lower concentration. A hypotonic solution contains less solutes and more water than the contents inside of the cell, so water will move from outside of the cell to inside, causing it to swell. Which is not an effect of photo- oxidation? A. loss of surface smoothness

What is the most abundant element in the universe? A. nitrogen B. hydrogen C. oxygen D. helium Correct Answer C. oxygen Hydrogen is the most abundant element in the universe, followed by helium and then oxygen. A solution that contains the maximum amount of dissolved solute is said to be

Although she is hungry, she is not going to eat. D. She is hungry but she's not going to eat. Correct Answer C. Although she is hungry, she is not going to eat. "Although she is hungry, she is not going to eat." is correct. A dependent clause begins with words such as although, since, if, when, and because. A dependent clause cannot stand on its own, so it may also be referred to as a "weak" clause. What would be considered the dependent clause in this sentence? "The students could finally see the bus, which was running 15

minutes behind schedule." A. could finally see the bus B. which was running 15 minutes behind schedule C. running 15 minutes behind schedule D. The students could finally see the bus Correct Answer B. which was running 15 minutes behind schedule

This one is not, so you would add the exponents to simplify it: 2 + 4 = 6, so x2x4=x6. Lance makes $11.35 an hour and earns time and a half pay for every hour over 40. If Lance worked 47 hours this week, about how much will his paycheck be? Round to the hundredths place. A. $546. B. $ C. $573. D. $521.37 Correct Answer C. $573. $573.18 is correct because $11.35 an hour x 40 hours a week equals $454. Time and a half pay for Lance would be $17.025, and you figure that out by multiplying $11.35 an hour by 1.5. Then multiply $17.025 times 7 overtime hours to get $119.175. Lastly, add $454 and $119.175 and you will get $573.175. Rounded to the hundredth place would be $573.18. Dawn has a 20% off one shirt coupon at her favorite store. If she buys 3 shirts at $29.99 each and uses her coupon, how much will her total bill be? Round to the nearest hundredth. A. $89. B. $86. C. $83. D. $71.98 Correct Answer C. $83. $83.97 is correct because $29.99 multiplied by 3 shirts is $89.97. To get 20% off of ONE shirt, $29.99 is multiplied by 0.20, which

equals $5.998. You subtract $5.998 from $89.97 to get $83.972. Rounded to the nearest hundredth you would get the correct answer, $83.97. What is 0.85 x 0.65? A. 0. B. 0.

According to the accompanying text, what are the names of the three basic blood cells? A complete blood count (CBC) is one of the most useful and requested types of analysis in medical practice. A CBC searches for all the cells that exist in the blood, which are divided into three basic types: white blood cells (leukocytes), platelets, and red blood cells (erythrocytes). All of these blood cells are produced in the bone marrow and correspond to a specific exam, integrated in the CBC: erythrogram, leukogram, and thrombogram. The erythrogram studies red blood cells. Among other tests, it includes a red blood cell count, a hematocrit, and hemoglobin. When these levels are low, the patient may be suffering from anemia, which can be caused by anything from heavy menstrual bleeding to Addison's disease. A diagnosis of polycythemia may be made if the number of red blood cells is increased. The leukogram is the test that evaluates the number of white cells present in the blood, which should vary between 4,000 and 10,000 cells per cubic millimeter in most adults. High values of white blood cells are seen with infection or severe emotional/physical stress, while AIDS and chemotherapy are two causes for low values. The thrombogram is the analysis of platelets, the cells responsible for coagulation. The main function of platelets is to help stop bleeding by helping form a clot. They do this by secreting proteins from their surface that allow them to stick to vessels and each other. Low values of platelets are seen with pregnancy or an enlarged spleen, whereas high values are seen with cancers or iron deficiency. A. red blood cells, erythrocytes, and platelets B. leukocytes, platelets, and erythrocytes C. white blood cells, leukocytes, and platelets D. erythrograms, leukograms, and thrombograms Correct Answer B. leukocytes, platelets, and erythrocytes The three basic blood cells are white blood cells (also called leukocytes), platelets, and red blood cells (also called erythrocytes). Referring to the attached passage, what is the name of the disease characterized by a high number of red blood cells? A complete blood count (CBC) is one of the most useful and requested types of analysis in medical practice. A CBC searches for all the cells that exist in the blood, which are divided into three basic types: white blood cells (leukocytes), platelets, and red blood cells (erythrocytes). All of these blood

cells are produced in the bone marrow and correspond to a specific exam, integrated in the CBC: erythrogram, leukogram, and thrombogram.
