1. Which preposition best completes the sentence: 'She borrowed money from her friend.'?
- A. of
- B. from
- C. on
- D. for
Correct answer: B
Rationale: The correct preposition to use in this sentence is 'from' as it indicates the source of the borrowed money. 'Of' (Choice A) is incorrect as it does not convey the idea of obtaining something from a specific person. 'On' (Choice C) is also incorrect as it does not relate to borrowing money from someone. 'For' (Choice D) is incorrect as it implies a different purpose than borrowing money from her friend. Therefore, the most appropriate preposition in this context is 'from', making the sentence grammatically correct and conveying the intended meaning.
2. Scoliosis is a condition characterized by abnormal lateral curvature of the spine. Which part of the spine is most commonly affected?
- A. Cervical spine (neck)
- B. Thoracic spine (upper back)
- C. Lumbar spine (lower back)
- D. All of the above
Correct answer: B
Rationale: Scoliosis most commonly affects the thoracic spine, which is the upper back region. While scoliosis can potentially affect any part of the spine, the thoracic spine is the most frequently involved area. This region is more commonly affected due to the natural structural curves of the spine and the biomechanics of the thoracic area. The cervical spine (neck) and lumbar spine (lower back) can also be affected by scoliosis, but the thoracic spine is the primary area of involvement in most cases. Therefore, the correct answer is B, as it is the part of the spine most commonly affected by scoliosis.
3. What is the role of hemoglobin in the human body?
- A. Transport oxygen in red blood cells
- B. Bind oxygen to red blood cells
- C. Carry carbon dioxide from tissues to lungs
- D. Help red blood cells transport oxygen
Correct answer: D
Rationale: The correct answer is D: 'Help red blood cells transport oxygen.' Hemoglobin acts as a carrier molecule in red blood cells, binding to oxygen in the lungs and releasing it in the tissues. It facilitates the transport of oxygen from the lungs to the tissues and aids in returning carbon dioxide from the tissues to the lungs. Choices A, B, and C are incorrect because hemoglobin itself does not transport oxygen independently or bind oxygen to red blood cells nor does it carry carbon dioxide from tissues to lungs; instead, it assists red blood cells in the transportation of oxygen.
4. A child complains of heavy breathing even when relaxing. They are an otherwise healthy child with no history of respiratory problems. What might be the issue?
- A. Asthma
- B. Blood clot
- C. Hyperventilation
- D. Exercising too hard
Correct answer: C
Rationale: In this scenario, where a child complains of heavy breathing even when relaxing and has no history of respiratory problems, the most likely issue is hyperventilation. Hyperventilation is an abnormal breathing pattern where a person breathes in excess of the body's requirements. It can be triggered by stress, anxiety, panic attacks, or lower-than-normal carbon dioxide levels in the blood. Unlike asthma, a blood clot, or exercising too hard, hyperventilation fits the symptoms described and is more common in individuals without a history of respiratory problems.
5. Homologous structures are those that:
- A. Have the same function but different origins
- B. Have different functions but the same origin
- C. Are similar in appearance and function due to shared ancestry
- D. Are identical in both appearance and function
Correct answer: C
Rationale: Homologous structures are defined as anatomical features that are similar in appearance and function due to shared ancestry. This means that these structures are inherited from a common ancestor and may have evolved to fulfill different functions in different species. Option A, which mentions structures with the same function but different origins, describes analogous structures, not homologous ones. Option B, which refers to structures with different functions but the same origin, actually characterizes vestigial structures. Option D, stating that structures are identical in appearance and function, does not necessarily imply homology; such structures could result from convergent evolution rather than shared ancestry. Understanding homologous structures provides insights into the evolutionary relationships between different species and supports the concept of common descent.
