Scientific Reasoning

1. What is the primary difference between science and pseudoscience?

Correct answer: B

Rationale: Both science and pseudoscience can explore similar topics, but their methods and reliance on evidence differentiate them.

2. A group of antibiotics that target the cell wall of bacteria are classified as:

Correct answer: A

Rationale: Rationale: Penicillins are a group of antibiotics that target the cell wall of bacteria by inhibiting the synthesis of peptidoglycan, a key component of the bacterial cell wall. By interfering with cell wall synthesis, penicillins weaken the cell wall, leading to bacterial cell lysis and death. This mechanism of action makes penicillins effective against a wide range of bacteria, particularly Gram-positive bacteria. Tetracyclines (B), Macrolides (C), and Fluoroquinolones (D) have different mechanisms of action and do not specifically target the bacterial cell wall. Tetracyclines inhibit protein synthesis, Macrolides interfere with bacterial ribosomes, and Fluoroquinolones target bacterial DNA gyrase and topoisomerase IV.

3. Which part of the brain is responsible for coordinating various sensory inputs, regulating sleep, and maintaining wakefulness?

Correct answer: d

Rationale: The correct answer is D: Reticular formation. The reticular formation is a network of neurons located in the brainstem that plays a crucial role in regulating consciousness, arousal, and sleep-wake transitions. It receives sensory inputs from various parts of the body and helps coordinate these inputs to maintain wakefulness and alertness. While the cerebrum is responsible for higher cognitive functions and the hypothalamus regulates various physiological processes like body temperature and hunger, the reticular formation specifically focuses on integrating sensory information and controlling wakefulness.

4. What is the function of introns in eukaryotic genes?

Correct answer: C

Rationale: Rationale: A) Introns do not code for protein sequences. Exons are the segments of DNA that code for proteins. B) While introns can indirectly influence gene regulation, their primary function is not directly involved in gene regulation. C) Introns are non-coding regions of DNA that are transcribed into pre-mRNA but are removed during mRNA processing through a process called splicing. This allows only the exons to be included in the mature mRNA that will be translated into proteins. D) While introns were once thought to be non-functional remnants of ancient DNA, research has shown that they can have regulatory functions and play a role in gene expression.

5. What does the term "colligative property" refer to in solutions?

Correct answer: b

Rationale: Colligative properties are dependent on the number of solute particles in a solution, not their nature. The other choices do not accurately define colligative properties.

6. What is the main argument presented in favor of UBI?

Correct answer: C

Rationale: The passage emphasizes UBI's potential to alleviate poverty and reduce inequality, aligning with C.
