1. When studying vocabulary, a student notices that the words circumference, circumnavigate, and circumstance all begin with the prefix circum-. The student uses their knowledge of affixes to infer that all of these words share what related meaning?
- A. Around, surrounding
- B. Travel, transport
- C. Size, measurement
- D. Area, location
Correct answer: A
Rationale: The prefix circum- means 'around' or 'surrounding.' In words like circumference (the distance around a circle), circumnavigate (to travel around something), and circumstance (the conditions surrounding an event), the prefix implies the idea of being around or encompassing. Choices B, C, and D are incorrect because the words do not primarily relate to travel, size, or area; instead, they share the common theme of being around or surrounding something.
2. Which of the following best describes a plane that divides the body into upper and lower portions?
- A. Coronal
- B. Transverse
- C. Oblique
- D. Median
Correct answer: B
Rationale: The correct answer is B: Transverse. A transverse plane, also known as a horizontal plane, divides the body into upper and lower portions. This plane is perpendicular to the long axis of the body. Coronal planes divide the body into anterior and posterior portions. Oblique planes pass through the body at an angle, neither strictly horizontal nor vertical. The median plane passes longitudinally through the body, dividing it into equal left and right halves.
3. During which of the following stages does crossing over occur?
- A. Mitosis Prophase
- B. Meiosis Prophase I
- C. Meiosis Prophase II
- D. Interphase
Correct answer: B
Rationale: Crossing over occurs during Prophase I of meiosis. This stage is specifically associated with genetic recombination, where homologous chromosomes exchange genetic material. This process contributes to genetic diversity by creating new combinations of alleles. Choices A, C, and D are incorrect. In mitosis, crossing over does not occur as it involves the separation of replicated chromosomes. Meiosis Prophase II is focused on the reformation of nuclei and does not involve crossing over. Interphase is a stage where the cell prepares for division and is not associated with crossing over.
4. During January, Dr. Lewis worked 20 shifts. During February, she worked three times as many shifts as she did during January. During March, she worked half the number of shifts she worked during February. Which equation below describes the number of shifts Dr. Lewis worked in March?
- A. shifts = 20 + 3 + 1/2
- B. shifts = (20)(3)(1/2)
- C. shifts = (20)(3) + 1/2
- D. shifts = 20 + (3)(1/2)
Correct answer: B
Rationale: During January, Dr. Lewis worked 20 shifts. Shifts for January = 20. During February, she worked three times as many shifts as she did during January. Shifts for February = (20)(3) = 60. During March, she worked half the number of shifts she worked in February. Shifts for March = (60)(1/2) = 30. Therefore, the correct equation to describe the number of shifts Dr. Lewis worked in March is 'shifts = (20)(3)(1/2)', representing the calculation based on the given scenario. Choices A, C, and D do not accurately represent the correct mathematical relationship between the shifts worked in the different months, making them incorrect.
5. What is bile, where is it produced, where is it stored, and what is its function?
- A. Produced in the pancreas, stored in the liver, aids in digestion
- B. Produced in the liver, stored in the gallbladder, aids in fat digestion
- C. Produced in the stomach, stored in the pancreas, neutralizes acid
- D. Produced in the gallbladder, stored in the liver, breaks down proteins
Correct answer: B
Rationale: Bile is a digestive fluid produced in the liver, stored in the gallbladder, and it aids in the digestion of fats by emulsifying them. Emulsification helps to break down fats into smaller particles, facilitating their digestion by enzymes in the small intestine. Choice A is incorrect because bile is not produced in the pancreas, and it is not stored in the liver. Choice C is incorrect as bile is not produced in the stomach, and it does not neutralize acid. Choice D is also incorrect as bile is not produced in the gallbladder, and its primary function is not to break down proteins.
