Chemistry

1. What is the coefficient of oxygen in the balanced chemical equation for the combustion of methane (CH4)?

Correct answer: b

Rationale: The balanced equation is CH4 + 2O2 → CO2 + 2H2O, so the coefficient of oxygen is 2.

2. What type of intermolecular force is responsible for the high surface tension of water?

Correct answer: A

Rationale: The high surface tension of water is due to the strong hydrogen bonding between water molecules. Hydrogen bonding is a type of intermolecular force that occurs when a hydrogen atom is covalently bonded to a highly electronegative atom (such as oxygen in water) and is attracted to another electronegative atom nearby. This results in a strong attraction between water molecules at the surface, leading to a high surface tension.

3. When you push a book across a table, the book experiences an equal and opposite force from the table. Why doesn't the table move as well?

Correct answer: C

Rationale: While Newton's third law states that for every action, there is an equal and opposite reaction, the unbalanced force acting on each object depends on their respective masses. The larger mass of the table (compared to the book) experiences a smaller acceleration, making its movement almost imperceptible.

4. A honeycomb cell has six equal sides, each measuring 8mm. What is its perimeter?

Correct answer: C

Rationale: Multiply the side length by the number of sides: perimeter = number of sides * side length = 6 * 8mm = 48mm.

5. The structural and functional unit of the kidney responsible for filtering blood is the:

Correct answer: A

Rationale: The correct answer is A, Nephron. The nephron is the structural and functional unit of the kidney responsible for filtering blood. It consists of the glomerulus, renal tubule, and collecting duct. The nephron's filtration process plays a crucial role in removing waste products, regulating electrolyte balance, and maintaining blood pressure. The other options, B: Ureter, C: Urethra, and D: Bladder, are not responsible for filtering blood. The ureter transports urine from the kidneys to the bladder, the urethra is responsible for urine excretion from the bladder, and the bladder stores urine before excretion. Therefore, the nephron is specifically designed for the filtration process within the kidney.

6. Testosterone is a crucial hormone in the male reproductive system. What is its primary function?

Correct answer: B

Rationale: The correct answer is B: Sperm production and development. Testosterone is a hormone primarily produced in the testes and is essential for the development of male reproductive tissues, including the testes and prostate. It plays a key role in the production of sperm cells (spermatogenesis) and the development of secondary sexual characteristics in males, such as facial hair and muscle mass. Testosterone is not involved in egg production (A), regulation of the menstrual cycle (C), or milk production (D) as these are functions associated with female reproductive hormones.
