1. The final sentence suggests that users should approach social media with a healthy dose of
- A. Enthusiasm and optimism about its potential for connection and engagement.
- B. Skepticism and critical thinking towards the information encountered online.
- C. Acceptance of its flaws and a passive reliance on its features for interaction.
- D. Indifference towards its impacts and an absence of any effort to manage its use.
Correct answer: B
Rationale: The emphasis on "critical thinking" and "skepticism" suggests the importance of approaching social media with a cautious and discerning mind, aligning with B
2. Which vitamin plays a crucial role in calcium absorption in the small intestine?
- A. Vitamin A
- B. Vitamin C
- C. Vitamin D
- D. Vitamin E
Correct answer: C
Rationale: The correct answer is C: Vitamin D. Vitamin D plays a crucial role in calcium absorption in the small intestine because it helps regulate the levels of calcium and phosphorus in the body. When vitamin D is present, it stimulates the production of proteins that facilitate the absorption of calcium from the intestine into the bloodstream. Without adequate levels of vitamin D, the body struggles to absorb calcium efficiently, which can lead to weakened bones and other health issues. While vitamins A, C, and E are important for various functions in the body, they do not directly impact calcium absorption in the same way that vitamin D does.
3. Identify the adjective in the following sentence: The colorful sunset painted the sky with vibrant hues.
- A. sunset
- B. with
- C. colorful
- D. painted
Correct answer: C
Rationale: Adjectives modify nouns and pronouns. The adjective "colorful" describes the noun "sunset".
4. Which of the following describes the difference between prokaryotic and eukaryotic cells?
- A. Prokaryotic cells have a nucleus, while eukaryotic cells don't.
- B. Eukaryotic cells are simpler in structure than prokaryotic cells.
- C. Prokaryotic cells have membrane-bound organelles, while eukaryotic cells don't.
- D. Eukaryotic cells have a true nucleus and membrane-bound organelles, while prokaryotic cells lack these.
Correct answer: A
Rationale: The correct answer is A: 'Prokaryotic cells have a nucleus, while eukaryotic cells don't.' Prokaryotic cells lack a membrane-bound nucleus and other membrane-bound organelles, while eukaryotic cells have a true nucleus enclosed within a nuclear membrane. This distinction is a fundamental difference between the two cell types. Choice B is incorrect because eukaryotic cells are actually more complex than prokaryotic cells due to their membrane-bound organelles. Choice C is incorrect because prokaryotic cells lack membrane-bound organelles. Choice D is incorrect because eukaryotic cells have both a true nucleus and membrane-bound organelles, unlike prokaryotic cells. Understanding this key difference is crucial in understanding the diversity of cell types in living organisms.
5. Which division of the autonomic nervous system is responsible for the "rest and digest" response, promoting relaxation and conservation of energy?
- A. Sympathetic nervous system
- B. Parasympathetic nervous system
- C. Somatic nervous system
- D. Central nervous system
Correct answer: b
Rationale: The correct answer is B, the parasympathetic nervous system. This division of the autonomic nervous system is responsible for the "rest and digest" response, promoting relaxation and conservation of energy. When activated, it slows the heart rate, increases digestion, and helps the body rest and recover. The sympathetic nervous system, on the other hand, is responsible for the "fight or flight" response, preparing the body for action. The somatic nervous system controls voluntary movements, and the central nervous system consists of the brain and spinal cord, coordinating all nervous system functions.
6. Which part of the brain controls balance and coordination?
- A. Cerebellum
- B. Hypothalamus
- C. Occipital lobe
- D. Corpus callosum
Correct answer: A
Rationale: Rationale: The cerebellum is the part of the brain responsible for coordinating voluntary movements, balance, and posture. It receives information from the sensory systems, the spinal cord, and other parts of the brain to regulate motor movements. The hypothalamus is involved in regulating various bodily functions such as temperature, hunger, and thirst. The occipital lobe is primarily responsible for processing visual information. The corpus callosum is a structure that connects the two hemispheres of the brain and facilitates communication between them.
