Helicase unwinds the DNA double helix by breaking hydrogen bonds between complementary bases.

4. Which of the following hormones is secreted in response to low blood glucose levels?

1. Which of the following compounds exhibits both ionic and covalent bonding?

a) NaCl b) CH₄ c) NaOH d) H₂O

NaOH contains an ionic bond between Na⁺ and OH⁻, and a covalent bond within the OH⁻ group.

2. Which of the following is the correct order of increasing ionization energy?

a) Na < Mg < Al < Si b) Na < Al < Mg < Si c) Si < Al < Mg < Na d) Mg < Na < Si < Al

Ionization energy increases across a period. The correct order is Na < Mg < Al < Si.

3. Which of the following is the correct hybridization of the central atom in SF₆?

a) sp³ b) sp³d c) sp³d² d) sp²

SF₆ has six bonding pairs around sulfur, requiring sp³d² hybridization.

4. Which of the following statements about the equilibrium constant (K) is correct?

a) K changes with the concentration of reactants. b) K changes with temperature. c) K changes with the pressure of the system. d) K remains constant under all conditions.

The equilibrium constant (K) is only affected by temperature, not by concentration or pressure.

5. Which of the following is the correct expression for the rate law of the reaction: 2A + B → C, if the reaction is first order in A and second order in B?

a) Rate = k[A][B] b) Rate = k[A]²[B] c) Rate = k[A][B]² d) Rate = k[A]²[B]²

The rate law is determined by the reaction order: Rate = k[A]¹[B]².

1. A ball is thrown vertically upward with an initial velocity of 20 m/s. What is the maximum height it reaches? (Take g = 10 m/s²)

a) 15 m b) 20 m c) 25 m d) 30 m

Using the formula v² = u² - 2gh, where v = 0 at maximum height, h = u² / 2g = (20²) / (2 × 10) = 20 m.

2. A 2 kg block is pushed with a force of 10 N on a rough surface with a coefficient of friction 0.2. What is the acceleration of the block?

a) 2 m/s² b) 3 m/s² c) 4 m/s² d) 5 m/s²

Net force = Applied force - Frictional force. Friction = μmg = 0.2 × 2 × 10 = 4 N. Net force = 10 - 4 = 6 N. Acceleration = F/m = 6/2 = 3 m/s².

3. A circuit has a 12 V battery connected to a 6 Ω resistor. What is the power dissipated in the resistor?

a) 12 W b) 24 W c) 36 W d) 48 W

Power = V² / R = 12² / 6 = 24 W.

4. A ray of light passes from air (n = 1) into water (n = 1.33) at an angle of incidence of 30°. What is the angle of refraction?

a) 18.5° b) 20.1° c) 22.0° d) 25.0°

Using Snell's Law: n₁sinθ₁ = n₂sinθ₂. sinθ₂ = sin30° / 1.33 = 0.5 / 1.33 ≈ 0.375. θ₂ ≈ 22.0°.

5. A 5 μF capacitor is connected to a 10 V battery. What is the energy stored in the capacitor?

a) 0.25 mJ b) 0.5 mJ c) 1.0 mJ d) 2.5 mJ

Energy = 0.5 × C × V² = 0.5 × 5 × 10⁻⁶ × 10² = 0.5 mJ.

1. Identify the sentence with correct punctuation:

a) The doctor said "You need rest". b) The doctor said, "you need rest." c) The doctor said, "You need rest." d) The doctor said "you need rest."

The correct punctuation includes a comma before the quotation and capitalization of the first word inside the quotation.

2. Choose the correct meaning of the idiom: "Burning the midnight oil."

a) Wasting time b) Working late into the night c) Lighting a lamp d) Relaxing after work

"Burning the midnight oil" refers to working late at night, often to meet deadlines or study.

3. Which of the following sentences uses the subjunctive mood correctly?

a) If I was you, I would study harder. b) If he was here, he would help us. c) If she was taller, she could reach the shelf. d) If I were you, I would study harder.

The subjunctive mood uses "were" instead of "was" in hypothetical or contrary-to-fact statements.

4. Identify the sentence with correct parallel structure:

a) She likes dancing, to swim, and biking. b) She likes to dance, swimming, and to bike. c) She likes dancing, swimming, and biking. d) She likes to dance, to swim, and biking.

Parallel structure ensures that all elements in a list or series follow the same grammatical form.

5. Choose the correct sentence that uses an appropriate conditional clause:

a) If he will study, he will pass the exam. b) If he studies, he will pass the exam. c) If he studied, he will pass the exam. d) If he had studied, he will pass the exam.

The first conditional uses the present tense in the "if" clause and the future tense in the main clause.

1. If all doctors are professionals, and some professionals are researchers, which of the following must be true?

a) All doctors are researchers b) No doctors are researchers c) Some doctors may be researchers d) All researchers are doctors

Some doctors may be researchers, but it is not definitive for all.

2. If A is twice as old as B, and B is three years older than C, which of the following is always true?

a) A is three times older than C b) A is six years older than C c) B is half the age of A d) C is older than A

If A = 2B and B = C + 3, then A = 2(C + 3), making A six years older than C.

3. All triangles are polygons. Some polygons are quadrilaterals. Which of the following is logically correct?

a) All triangles are quadrilaterals b) No triangles are quadrilaterals c) Some polygons are not triangles d) All polygons are triangles

Some polygons are quadrilaterals, so not all polygons are triangles.

4. If it rains, the ground gets wet. If the ground is wet, plants grow. The plants are growing. What can be concluded?

a) It is raining b) It will rain c) The ground is wet d) It never rains

The plants growing implies the ground is wet, but it does not necessarily mean it is raining.

5. If X implies Y, and Y implies Z, which of the following is true?

a) X and Z are independent b) X implies Z c) Z implies X d) Y implies X

If X implies Y and Y implies Z, then by transitivity, X implies Z.
