1. What is the SI unit of measurement for momentum?
- A. Newton (N)
- B. Kilogram-meter per second (kg·m/s)
- C. Joule (J)
- D. Newton-second (N·s)
Correct answer: b
Rationale: Momentum is measured in kilogram-meter per second (kg·m/s).
2. Positive integers are greater than zero. Which of the following expressions results in the largest positive number?
- A. (2 + 3)^2
- B. 5 x 7 + 2
- C. 10^2 - 4^2
- D. (8 - 1) x 3
Correct answer: C
Rationale: 10^2 - 4^2 = 100 - 16 = 84
3. What is the main idea of the passage?
- A. Petra is a modern city built for tourism.
- B. Petra's historical significance lies in its architectural achievements.
- C. Petra's prosperity was linked to its strategic location on trade routes.
- D. Petra's obscurity remains a mystery despite its rediscovery.
Correct answer: C
Rationale: B mentions Petra's architecture, but not its connection to trade. A and D are factually incorrect and not supported by the passage. Choice C accurately identifies Petra's rise and fall as tied to its position on the Silk Road, making it the main idea.
4. Which type of epithelial tissue lines the inner lining of your intestines, responsible for absorption?
- A. Stratified squamous
- B. Simple columnar
- C. Stratified cuboidal
- D. Transitional epithelium
Correct answer: B
Rationale: The correct answer is B: Simple columnar. Simple columnar epithelial tissue is well-suited for absorption because of its single layer of tall, column-shaped cells with microvilli on the surface, increasing surface area for absorption. This type of tissue is found in the inner lining of the intestines where absorption of nutrients occurs. Stratified squamous epithelium is more protective and found in areas subject to wear and tear, like the skin. Stratified cuboidal and transitional epithelium are not typically involved in absorption processes. Therefore, simple columnar epithelial tissue is the most appropriate choice for lining the inner surface of the intestines for absorption.
5. Which gland in the endocrine system is responsible for the production of red blood cells?
- A. Pituitary gland
- B. Thyroid gland
- C. Thymus gland
- D. Parathyroid gland
Correct answer: C
Rationale: The correct answer is the Thymus gland (option C). The Thymus gland is responsible for the production and maturation of T-lymphocytes, a type of white blood cell involved in immune responses. Red blood cells are not produced by any endocrine gland; instead, they are produced in the bone marrow. The Pituitary gland (option A) secretes hormones that control various body functions, the Thyroid gland (option B) regulates metabolism, and the Parathyroid gland (option D) regulates calcium levels in the blood. Therefore, the Thymus gland is not responsible for the production of red blood cells, making it the correct answer in this case.
6. Which of the following is NOT a major component of a healthy blood pressure reading?
- A. Systolic pressure (peak pressure during ventricular contraction).
- B. Diastolic pressure (pressure within arteries during ventricular relaxation).
- C. Pulse pressure (difference between systolic and diastolic pressure).
- D. Blood oxygen saturation While blood oxygen levels are crucial for overall health, they are not directly reflected in a blood pressure reading.
Correct answer: A
Rationale: The correct answer is A. Systolic pressure is a major component of a healthy blood pressure reading as it represents the peak pressure in the arteries during ventricular contraction. Diastolic pressure, representing the pressure in the arteries during ventricular relaxation, is also a key component. Pulse pressure, the difference between systolic and diastolic pressure, provides additional information about the cardiovascular system. Blood oxygen saturation, while important for overall health, is not directly measured in a blood pressure reading. Therefore, it is not a major component of a healthy blood pressure reading.
