1. What is the process by which a cell divides into two or more new cells?

• A. Mitosis
• B. Meiosis
• C. Both mitosis and meiosis
• D. None of the above

Correct answer: A

Rationale: Mitosis is the process by which a cell divides into two identical daughter cells. This type of cell division is essential for growth, repair, and maintenance of multicellular organisms. Meiosis, on the other hand, is a type of cell division that produces gametes (sperm and egg cells) with half the number of chromosomes as the parent cell. Meiosis does not directly result in the formation of new cells, as it is specifically geared towards the production of reproductive cells. Therefore, the correct answer is A. Option C, stating both mitosis and meiosis, is incorrect because meiosis is not involved in the general process of cell division to produce new cells; it is specialized for gamete formation. Option D is incorrect because mitosis is indeed the process responsible for cell division in which one cell divides into two daughter cells, making it the accurate choice for this question.

2. Which option best exemplifies an author's use of alliteration and personification?

• A. Her mood hung about her like a weary cape, very dull from wear.
• B. It shuddered, swayed, shook, and screamed its way into dust under hot flames.
• C. The house was a starch sentry, warning visitors away.
• D. At its shoreline, visitors swore they heard the siren call of the cliffs above.

Correct answer: B

Rationale: Choice B best exemplifies an author's use of alliteration and personification. The sentence 'It shuddered, swayed, shook, and screamed its way into dust under hot flames' personifies an inanimate object (it) by attributing human actions to it, combining alliteration with the repeated 's' sounds. Choices A, C, and D do not contain both alliteration and personification. Choice A mainly focuses on simile and lacks alliteration. Choice C features personification but lacks alliteration. Choice D includes personification but lacks alliteration as well.

3. What is the importance of RNA splicing?

• A. Removes introns from the mRNA molecule
• B. Adds the poly-A tail to the mRNA molecule
• C. Activates the mRNA molecule for translation
• D. Modifies the structure of the protein

Correct answer: A

Rationale: RNA splicing is a crucial process in gene expression where non-coding regions called introns are removed from the pre-mRNA molecule, and the remaining coding regions called exons are joined together to form the mature mRNA molecule. This process ensures that only the protein-coding sequences are retained in the mRNA for translation, allowing for the production of functional proteins. Therefore, option A is the correct answer as it accurately describes the importance of RNA splicing in generating mature mRNA molecules for protein synthesis. B) Adding the poly-A tail to the mRNA molecule is a post-transcriptional modification that occurs after RNA splicing and is not directly related to the process of removing introns. C) Activating the mRNA molecule for translation is typically achieved through the addition of a 5' cap and the poly-A tail, rather than through RNA splicing. D) Modifying the structure of the protein is not directly related to the process of RNA splicing, which primarily focuses on mRNA maturation by removing non-coding introns.

4. Which of the following examples is a complete sentence?

• A. Let me know.
• B. On the subject of philosophy.
• C. Depending on the type of books you like.
• D. Where there are lots of people.

Correct answer: A

Rationale: The correct answer is A: 'Let me know.' This is a complete sentence as it contains a subject ('me') and a verb ('know'). Choice B, 'On the subject of philosophy,' is a prepositional phrase and does not form a complete sentence as it lacks a subject and verb. Choice C, 'Depending on the type of books you like,' is a dependent clause and does not stand alone as a complete sentence. Choice D, 'Where there are lots of people,' is a dependent clause as it begins with a subordinating conjunction ('where') and does not function as a complete sentence on its own.

5. Which part of the brain is responsible for memory and learning?

• A. Cerebellum
• B. Cerebrum
• C. Medulla oblongata
• D. Brainstem

Correct answer: B

Rationale: The correct answer is B - Cerebrum. The cerebrum, not the cerebellum as in choice A, is the largest part of the brain and is responsible for memory, learning, and higher cognitive functions. It processes sensory information, enables reasoning, and decision-making, all crucial for memory formation and learning processes. Choices C and D, Medulla oblongata and Brainstem respectively, do not primarily play roles in memory and learning processes. The Medulla oblongata is mainly involved in regulating vital autonomic functions like breathing and heart rate, while the Brainstem serves as a pathway for neural communication and houses essential control centers for basic life functions, not memory and learning.
