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. Acne vulgaris, commonly known as acne, is primarily caused by
- A. Dry skin (Dry skin can worsen acne but isn't the primary cause)
- B. Clogged pores and excess oil production
- C. Bacterial infection alone (Bacteria play a role but not the sole cause)
- D. Vitamin deficiency
Correct answer: B
Rationale: The correct answer is B: 'Clogged pores and excess oil production.' Acne vulgaris, or acne, is primarily caused by a combination of factors including excess sebum (oil) production by the skin's sebaceous glands and the accumulation of dead skin cells, leading to clogged pores. This environment provides a breeding ground for acne-causing bacteria, contributing to inflammation and the formation of pimples. While factors like dry skin, bacterial infections, and even vitamin deficiencies can exacerbate acne, they are not the primary cause. Thus, B is the most accurate option for the primary cause of acne.
3. What is the term for a group of organisms that can interbreed and produce fertile offspring?
- A. Genus
- B. Phylum
- C. Kingdom
- D. Species
Correct answer: D
Rationale: Rationale: A species is defined as a group of organisms that can interbreed and produce fertile offspring. This ability to interbreed and produce fertile offspring is a key characteristic that distinguishes one species from another. In contrast, a genus (option A) is a taxonomic rank that includes one or more species that are closely related, while a phylum (option B) and a kingdom (option C) are higher taxonomic ranks that encompass multiple species.
4. What is the name of the bone marrow cavity in the long bones where red blood cells are produced?
- A. Periosteum
- B. Diaphysis
- C. Medullary cavity
- D. Epiphysis
Correct answer: B
Rationale: The correct answer is B: Diaphysis. The diaphysis is the shaft of a long bone where the medullary cavity is located. The medullary cavity is the central cavity of the diaphysis where red bone marrow is found and is responsible for producing red blood cells, white blood cells, and platelets. The periosteum is a dense membrane covering the outer surface of bones, not where red blood cells are produced. The epiphysis refers to the ends of long bones, while the medullary cavity is found in the diaphysis. Therefore, the correct choice is the diaphysis where the medullary cavity is located for red blood cell production.
5. What is the relationship between the frequency and wavelength of a wave?
- A. Inversely proportional
- B. Directly proportional
- C. No relationship
- D. Depend on the medium
Correct answer: a
Rationale: Frequency and wavelength have an inverse relationship - as one increases, the other decreases.
6. What is the unit of measurement for power?
- A. Joule (J)
- B. Newton (N)
- C. Watt (W)
- D. Kilogram-meter (kg·m)
Correct answer: c
Rationale: Power is measured in watts (W) in the SI unit system.
