1. Which of the following water-soluble vitamins is NOT synthesized in the large intestine?
- A. B6
- B. Biotin
- C. Pantothenic acid (Vitamin B5)
- D. Vitamin K
Correct answer: A
Rationale: The correct answer is A: B6. Vitamin B6 is not synthesized in the large intestine, while biotin, pantothenic acid (Vitamin B5), and Vitamin K can be synthesized by gut microflora. Biotin, B5, and K are examples of water-soluble vitamins that can be produced in the large intestine, but B6 needs to be obtained through dietary sources. Therefore, B6 is the correct answer as it is not synthesized within the large intestine, unlike the other options.
2. What is the term for the time it takes for a wave to complete one full cycle?
- A. Frequency
- B. Amplitude
- C. Period
- D. Wavelength
Correct answer: C
Rationale: The period of a wave is the time it takes for one complete cycle to occur. It is the duration between two successive points in the wave that are in the same phase. Frequency, on the other hand, refers to the number of cycles of a wave that occur in a given time period. Amplitude represents the maximum displacement of a wave from its equilibrium position. Wavelength is the distance between two consecutive points on a wave that are in phase. Therefore, the correct answer is 'Period' as it specifically refers to the time taken for a wave to complete one full cycle, distinguishing it from the other choices which represent different properties of a wave.
3. Which law of motion explains the behavior of rockets in space?
- A. Newton's First Law
- B. Newton's Second Law
- C. Newton's Third Law
- D. None of the above
Correct answer: C
Rationale: The correct answer is Newton's Third Law. Newton's Third Law states that for every action, there is an equal and opposite reaction. In the case of rockets in space, the action is the expulsion of gas from the rocket engines, and the reaction is the forward motion of the rocket. This law explains how rockets are able to propel themselves forward in the vacuum of space. Choices A and B are incorrect because Newton's First Law (inertia) and Second Law (F=ma) do not directly explain the behavior of rockets in space. Choice D is incorrect as Newton's Third Law specifically addresses the principle behind rockets' motion in space.
4. Which of the following bones belongs to the category of long bones?
- A. Femur
- B. Ribs and cranial bones
- C. Sesamoid
- D. Vertebrae and hip bones
Correct answer: A
Rationale: The correct answer is A: Femur. Long bones are characterized by their elongated shape, with examples including the femur, humerus, and tibia. These bones are essential for support, movement, and bone marrow production. Choice B, 'Ribs and cranial bones,' consists of flat bones, not long bones. Choice C, 'Sesamoid,' refers to small bones embedded within tendons and do not fall under the category of long bones. Choice D, 'Vertebrae and hip bones,' includes irregular bones that provide structural support and protection for vital organs, but they are not classified as long bones.
5. Which of the following is a function of the liver?
- A. Producing digestive enzymes
- B. Storing bile
- C. Filtering waste products from the blood
- D. Transporting nutrients to cells
Correct answer: B
Rationale: The correct function of the liver is to store bile. Bile is produced in the liver and stored in the gallbladder until it is needed to aid in the digestion of fats. While the liver does produce bile, its primary role is to store and release it. Choices A, C, and D are incorrect. Producing digestive enzymes is mainly the function of the pancreas, filtering waste products from the blood is primarily done by the kidneys, and transporting nutrients to cells is typically associated with the circulatory system rather than the liver.
