1. Which law of motion states that for every action, there is an equal and opposite reaction?

• A. Newton's First Law
• B. Newton's Second Law
• C. Newton's Third Law
• D. Law of Universal Gravitation

Correct answer: c

Rationale: Newton's Third Law states the action-reaction principle.

2. Based on the passage, the author most likely believes that

• A. Individual actions are insignificant in addressing climate change, and only large-scale initiatives matter.
• B. Adaptation to the changing climate is impossible, and societal collapse is inevitable.
• C. Transitioning to renewable energy and sustainable practices offers hope for mitigating climate change.
• D. The scientific evidence for climate change is unreliable, and further research is needed before taking action.

Correct answer: C

Rationale: The focus on global efforts, renewable energy, and sustainable practices suggests an optimistic outlook on mitigating climate change, aligning with C.

3. A triangular scarf has sides measuring 10cm, 12cm, and 15cm. What is its perimeter?

• A. 27cm
• B. 32cm
• C. 37cm
• D. 45cm

Correct answer: C

Rationale: Simply add the lengths of all sides: perimeter = side1 + side2 + side3 = 10cm + 12cm + 15cm = 37cm.

4. Which phenomenon explains the formation of rainbows in the sky?

• A. Diffraction
• B. Interference
• C. Refraction and dispersion of sunlight by water droplets.
• D. Reflection from clouds

Correct answer: C

Rationale: Refraction and dispersion of sunlight by water droplets in the atmosphere separate white light into its constituent colors, creating the rainbow phenomenon.

5. Which of the following factors would increase the solubility of a gas in a liquid?

• A. Decreasing temperature
• B. Increasing pressure
• C. Decreasing surface area
• D. Increasing particle size

Correct answer: b

Rationale: Henry's law states that the solubility of a gas in a liquid is directly proportional to the pressure of the gas above the liquid. The other choices would typically decrease solubility.

6. Which type of tissue is characterized by tightly packed cells with minimal extracellular matrix and provides structural support and protection?

• A. Epithelial tissue
• B. Connective tissue
• C. Muscle tissue
• D. Nervous tissue

Correct answer: B

Rationale: The correct answer is B: Connective tissue. Connective tissue is characterized by tightly packed cells with minimal extracellular matrix, which provides structural support and protection. Epithelial tissue, while also tightly packed, is specialized for lining and covering surfaces. Muscle tissue is composed of cells with contractile properties for movement, and nervous tissue is made up of neurons for transmitting electrical signals. Therefore, connective tissue best fits the description of being densely packed with cells and serving a structural support and protective function.
