Chemistry
1. What is the term for the chemical reaction that involves the loss of electrons?
- A. Reduction
- B. Oxidation
- C. Neutralization
- D. Precipitation
Correct answer: b
Rationale: Oxidation is the chemical reaction that involves the loss of electrons. The other choices describe different types of reactions.
2. What is the main consequence of a malfunctioning thyroid gland that produces abnormally low levels of thyroid hormones?
- A. Increased energy levels and weight loss
- B. Decreased heart rate and body temperature
- C. Enhanced muscle growth and bone development
- D. Faster metabolism and heightened alertness
Correct answer: B
Rationale: The correct answer is B: 'Decreased heart rate and body temperature.' When the thyroid gland produces abnormally low levels of thyroid hormones (hypothyroidism), it can lead to a decrease in metabolic rate, resulting in symptoms such as fatigue, weight gain, and feeling cold. A lower metabolic rate can slow down heart rate and decrease body temperature. The other options (A, C, D) are not characteristic of hypothyroidism. Increased energy levels and weight loss, enhanced muscle growth and bone development, and faster metabolism and heightened alertness are more commonly associated with hyperthyroidism, where the thyroid gland produces excess hormones.
3. What is the recommended daily fiber intake for adults?
- A. 10 grams
- B. 25 grams
- C. 35 grams
- D. 50 grams
Correct answer: B
Rationale: Rationale: The recommended daily fiber intake for adults is around 25 grams for women and 38 grams for men. Fiber is essential for maintaining a healthy digestive system, preventing constipation, and reducing the risk of chronic diseases such as heart disease and diabetes. Consuming an adequate amount of fiber can also help with weight management and promote overall well-being. Therefore, option B is the most appropriate answer based on the recommended daily intake guidelines for adults.
4. Which type of wave does not require a medium for propagation?
- A. Transverse wave
- B. Longitudinal wave
- C. Mechanical wave
- D. Electromagnetic wave
Correct answer: D
Rationale: Electromagnetic waves, like light and radio waves, can travel through a vacuum, unlike mechanical waves (sound, water waves) that require a medium to vibrate and transmit energy.
5. A circular bandage has a diameter of 6cm. What is the area covered by the bandage (area of a circle = πr^2)?
- A. 9Ï€ cm^2
- B. 18Ï€ cm^2
- C. 27Ï€ cm^2
- D. 36Ï€ cm^2
Correct answer: B
Rationale: Divide the diameter (6cm) by 2 to find the radius (3cm). Substitute into the formula and multiply by π to get 18π cm^2.
6. When proofreading your writing, focus on:
- A. Changing the wording to sound more original.
- B. Ignoring minor grammatical errors like typos.
- C. Checking for clarity, consistency, and overall flow.
- D. Replacing common words with thesaurus alternatives.
Correct answer: C
Rationale: Proofreading involves correcting errors, refining sentence structure, and ensuring the writing achieves its purpose, clarity, and consistency.
