1. What protein complex controls the progression of mitosis through its activation and degradation?
- A. Ribosome
- B. Cyclin-dependent kinase (CDK)
- C. Centriole
- D. Microtubule
Correct answer: B
Rationale: A) Ribosome: Ribosomes are cellular organelles responsible for protein synthesis and are not directly involved in controlling the progression of mitosis. B) Cyclin-dependent kinase (CDK): CDKs are a family of protein kinases that regulate the cell cycle, including the progression of mitosis. CDK activity is controlled by cyclins, which bind to CDKs to activate them at specific points in the cell cycle. The activation and degradation of cyclins regulate the activity of CDKs, which in turn control the progression of mitosis. C) Centriole: Centrioles are involved in organizing the microtubules of the mitotic spindle but do not directly control the progression of mitosis. D) Microtubule: Microtubules are structural components of the cytoskeleton and are involved in various cellular processes, including mitosis, but they do not control
2. Which structure is the largest part of the airway?
- A. Alveoli
- B. Bronchi
- C. Bronchioles
- D. Trachea
Correct answer: D
Rationale: The correct answer is the trachea. The trachea is the largest part of the airway and serves as the main passageway for air to enter and exit the lungs. It connects the larynx to the bronchi and is an essential component of the respiratory system. The alveoli, although crucial for gas exchange, are tiny air sacs in the lungs and not the largest part of the airway. Bronchi and bronchioles are smaller airway passages that branch off from the trachea, making them smaller in size compared to the trachea.
3. Which type of reaction typically undergoes condensation reactions?
- A. Catabolism
- B. Anabolism
- C. Exothermic
- D. Endothermic
Correct answer: B
Rationale: The correct answer is 'B: Anabolism.' Anabolic reactions typically involve condensation reactions, where smaller molecules are joined together to form larger molecules by releasing water as a byproduct. This process is fundamental in the synthesis of complex molecules such as proteins and nucleic acids. Choice A, 'Catabolism,' involves decomposition reactions where larger molecules are broken down into smaller ones, which is the opposite of condensation reactions. Choices C and D, 'Exothermic' and 'Endothermic,' refer to the heat exchange during a reaction and are not directly related to the process of condensation reactions.
4. What is the study of fungi known as?
- A. Virology
- B. Mycology
- C. Bacteriology
- D. Parasitology
Correct answer: B
Rationale: Mycology is the correct answer. Mycology is the branch of biology that specifically deals with the study of fungi. Fungi constitute a separate kingdom of organisms that include various forms such as yeasts, molds, and mushrooms. Virology (A) is the study of viruses, while Bacteriology (C) focuses on bacteria. Parasitology (D) is the study of parasites, which may include protozoa, helminths, and some fungi, but it is not solely dedicated to fungi.
5. What role does humor play in Wilde's critique of the aristocracy?
- A. To soften the harshness of the critique and make it more palatable.
- B. To make the critique more pointed and direct.
- C. To critique the aristocracy without alienating the audience.
- D. To entertain the audience with humor, while delivering a serious message.
Correct answer: C
Rationale: In Wilde's critique of the aristocracy, humor serves the purpose of critiquing without alienating the audience. By infusing humor into his work, Wilde can effectively highlight the flaws and absurdities of the upper classes while keeping the audience engaged and receptive. Option A is incorrect because the humor does not aim to soften the critique but rather to enhance its impact. Option B is incorrect as the humor in Wilde's work is not meant to make the critique more pointed and direct but rather more approachable. Option D is incorrect because while entertaining the audience, the primary function of humor in Wilde's critique is to provide a platform for social commentary without losing the audience's interest.
