1. Which preposition best completes the sentence: "She borrowed money _____ her friend."
- A. of
- B. from
- C. on
- D. for
Correct answer: B
Rationale: "From" indicates the source of the borrowed money.
2. The muscular tube that carries urine from the kidneys to the bladder is called the:
- A. Nephron
- B. Ureter
- C. Urethra
- D. Glomerulus
Correct answer: B
Rationale: The correct answer is B: Ureter. The ureter is the muscular tube that carries urine from the kidneys to the bladder. Nephrons are the functional units of the kidneys responsible for filtering blood. The urethra is the tube that carries urine from the bladder out of the body. The glomerulus is a cluster of blood vessels in the nephron that filters blood to form urine. Understanding the functions and locations of these structures is essential for comprehending the urinary system's overall process.
3. Dandruff is caused by
- A. Excessive sebum production (This can contribute to oily dandruff)
- B. Bacterial infection (This can cause scalp folliculitis, not dandruff)
- C. Overgrowth of a specific type of fungus on the scalp
- D. Lack of proper skin hydration
Correct answer: C
Rationale: Dandruff is primarily caused by an overgrowth of a specific type of fungus called Malassezia on the scalp. This fungus feeds on the natural oils produced by the hair follicles, leading to an inflammatory response in some individuals, resulting in flaking and itching. Excessive sebum production can contribute to oily dandruff by providing more food for the fungus. Bacterial infections, such as scalp folliculitis, can cause symptoms similar to dandruff but are not the primary cause. Lack of proper skin hydration can contribute to dry scalp conditions but is not the main cause of dandruff.
4. A scientist observes a new species of bird with uniquely shaped wings. They hypothesize that the wing shape allows for superior gliding ability. Which observation would most strongly support this hypothesis?
- A. The bird is found in mountainous regions.
- B. The bird has feathers with low friction.
- C. The bird can fly long distances without flapping.
- D. The bird's wing muscles are stronger than other birds.
Correct answer: C
Rationale: Direct observation of gliding ability directly tests the hypothesis about the wing shape's function. Other observations might be relevant but provide less direct evidence.
5. A car is moving in a circle at constant speed. Which of the following is NOT true about its motion?
- A. It has a constant centripetal acceleration
- B. It has a constant tangential velocity
- C. It experiences a force directed towards the center of the circle
- D. It covers the same distance in equal time intervals along its circular path
Correct answer: B
Rationale: In circular motion at a constant speed, the car has a constant centripetal acceleration (choice A), experiences a force directed towards the center of the circle (choice C), and covers the same distance in equal time intervals along its circular path (choice D). However, the tangential velocity of an object in circular motion at a constant speed changes continuously as it moves around the circle, so it is not constant (choice B).
6. What is the process of breaking down glucose into pyruvate called?
- A. Glycolysis
- B. Gluconeogenesis
- C. Krebs cycle
- D. Oxidative phosphorylation
Correct answer: A
Rationale: Rationale: A) Glycolysis is the process of breaking down glucose into pyruvate. This occurs in the cytoplasm of cells and is the first step in cellular respiration. B) Gluconeogenesis is the process of synthesizing glucose from non-carbohydrate sources, such as amino acids or glycerol, and is the opposite of glycolysis. C) The Krebs cycle, also known as the citric acid cycle, is a series of chemical reactions that occur in the mitochondria and is involved in the oxidation of acetyl-CoA to produce ATP and other energy carriers. D) Oxidative phosphorylation is the final stage of cellular respiration where ATP is produced through the transfer of electrons in the electron transport chain.
