English Grammar
1. The doctor carefully examined the patient. Which word is the comparative form of the adjective "careful"?
- A. careful
- B. carelessly
- C. more careful
- D. most careful
Correct answer: C
Rationale: The comparative form of an adjective compares two things.
2. What is the common name for the compound CH₃COOH?
- A. Acetic acid
- B. Formic acid
- C. Butyric acid
- D. Propionic acid
Correct answer: A
Rationale: CH₃COOH is commonly known as acetic acid. The other choices represent different organic acids.
3. The defining characteristic of an element is determined by the number of:
- A. Neutrons in its nucleus
- B. Electrons surrounding the nucleus
- C. Protons in its nucleus
- D. All of the above
Correct answer: C
Rationale: The correct answer is C: 'Protons in its nucleus.' An element is defined by the number of protons in its nucleus, known as the atomic number. This number determines the element's identity and its placement on the periodic table. Neutrons and electrons play important roles in an atom, but they do not define the element itself. Neutrons contribute to the atom's mass, while electrons are involved in chemical reactions and bonding. Therefore, the number of protons is the defining characteristic of an element.
4. In the process of osmosis, the solvent moves from an area of...
- A. Low solute concentration to high solute concentration
- B. Hotter solution to colder solution
- C. Colder solution to hotter solution
- D. High solute concentration to low solute concentration
Correct answer: D
Rationale: In osmosis, solvent molecules move across a semi-permeable membrane from an area of low solute concentration to high solute concentration. This movement is driven by the desire to equalize the concentration of solutes on both sides of the membrane. As a result, option A is the correct answer because the solvent will naturally flow towards the area with a higher concentration of solutes in order to balance the concentrations on both sides of the membrane. Options B and C are incorrect as osmosis is not influenced by temperature differences. Option D is incorrect as the solvent does not move towards areas of high solute concentration in osmosis.
5. What is the SI unit of measurement for acceleration?
- A. Meters per second (m/s)
- B. Newton (N)
- C. Meters (m)
- D. Meters per second squared (m/s²)
Correct answer: d
Rationale: Acceleration is measured in meters per second squared (m/s²) in the SI unit system.
6. The largest lymphatic vessel in the body is responsible for draining lymph from most of the body. What is it called?
- A. Jugular vein
- B. Thoracic duct
- C. Subclavian vein
- D. Aorta
Correct answer: B
Rationale: The correct answer is B: Thoracic duct. The thoracic duct is the largest lymphatic vessel in the body and is responsible for draining lymph from most of the body. It collects lymph from the left side of the head, neck, chest, abdomen, left arm, and lower extremities. The jugular vein (A) is a major blood vessel that drains blood from the head. The subclavian vein (C) is responsible for draining blood from the upper extremities. The aorta (D) is the main artery that carries oxygenated blood away from the heart. Therefore, the thoracic duct is the correct answer for the largest lymphatic vessel in the body.
