3. The human eye focuses light by adjusting the shape of its:
- A. Cornea
- B. Iris
- C. Lens
- D. Retina
Correct answer: C
Rationale: The human eye focuses light by adjusting the shape of its lens. The cornea is the transparent outer covering of the eye that helps to focus light, but it does not change shape. The iris regulates the amount of light entering the eye through the pupil but does not adjust the shape of the light. The retina is the layer at the back of the eye that receives and processes light signals but does not play a role in focusing light. Therefore, the correct answer is C, the lens, as it changes shape to focus light onto the retina, allowing for clear vision.
4. Which hormone, produced by the thyroid gland, plays a crucial role in regulating the body's metabolism, growth, and development?
- A. Calcitonin
- B. Parathyroid hormone (PTH)
- C. Thyroxine
- D. Insulin
Correct answer: c
Rationale: The correct answer is C: Thyroxine. Thyroxine, also known as T4, is a hormone produced by the thyroid gland that plays a crucial role in regulating the body's metabolism, growth, and development. It controls how the body uses energy, affects heart rate, and influences other vital functions. Calcitonin (A) is involved in calcium regulation, not metabolism. Parathyroid hormone (PTH) (B) is produced by the parathyroid glands and regulates calcium and phosphorus levels in the body. Insulin (D) is a hormone produced by the pancreas that regulates blood sugar levels, not metabolism or growth.
5. 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: The correct answer is B: Thoracic spine (upper back). Scoliosis typically affects the thoracic spine more commonly than the cervical or lumbar spine. The thoracic spine, which is the upper back region, is the most common area for the abnormal lateral curvature of the spine to occur in cases of scoliosis. This is due to the natural curvature and structure of the spine in this region. While scoliosis can affect other parts of the spine as well, the thoracic spine is most frequently impacted, making it the correct answer in this case.
6. What type of force opposes the motion of an object moving through a fluid (liquid or gas)?
- A. Gravitational force
- B. Tension force
- C. Viscous force
- D. Magnetic force
Correct answer: c
Rationale: Viscous force is the resistance experienced by an object moving through a fluid due to internal friction.
