1. A car is traveling on a curved road. What force keeps the car moving along the curved path?

• A. Gravitational force
• B. Normal force from the road
• C. Air resistance
• D. Friction between the tires and the road

Correct answer: D

Rationale: In this case, static friction acts between the tires and the road, providing the centripetal force required to keep the car moving in a circle even though it's traveling in a straight line relative to the ground.

2. She notes that there is an increasing unrest of the staff due to fatigue brought about by

• A. Evaluate the overall result of the unrest
• B. Initiate a group interaction
• C. Develop a plan and implement it
• D. Identify external and internal forces.

Correct answer: C

Rationale: The correct answer is C: 'Develop a plan and implement it.' In the given scenario, the staff is experiencing unrest due to fatigue, which is a serious issue affecting their well-being and productivity. By developing a plan to address the fatigue issue and implementing it effectively, the organization can provide necessary support to the staff, improve working conditions, and enhance overall morale and performance. This proactive approach is crucial in maintaining a healthy work environment and ensuring the well-being of the staff members. Options A, B, and D do not directly address the root cause of fatigue and unrest among the staff, making them less suitable answers.

3. What is the basic unit of heredity?

• A. Chromosome
• B. Cell
• C. Gene
• D. Organ

Correct answer: C

Rationale: Rationale: A gene is the basic unit of heredity that carries the instructions for making proteins, which determine an organism's traits. Genes are segments of DNA located on chromosomes within the cell. While chromosomes contain many genes, a gene itself is the fundamental unit of heredity responsible for passing on genetic information from one generation to the next. Cells are the basic structural and functional units of living organisms, but genes specifically carry genetic information. Organs are composed of tissues and serve specific functions within an organism, but they are not the basic unit of heredity.

4. What is the role of transfer RNA (tRNA) in protein synthesis?

• A. Transcribes DNA into mRNA
• B. Decodes the genetic code on mRNA
• C. Carries specific amino acids to the ribosomes bas(a) Carries amino acids to the ribosomes: This is the function of transfer RNA (tRNA), not ribosomal RNA. (b) Reads the genetic code on mRNA: This is the function of the ribosomes as a whole, not just the ribosomal RNA. (d) Controls the rate of protein synthesis: This is a more complex process involving various factors, not solely ribosomal RNA. ? ed on the mRNA
• D. Modifies the structure of proteins

Correct answer: C

Rationale: Rationale: A) Transcribes DNA into mRNA: This is the function of RNA polymerase, not transfer RNA (tRNA). tRNA is involved in protein synthesis, not transcription. B) Decodes the genetic code on mRNA: This is the function of tRNA during translation. tRNA molecules carry specific amino acids and recognize the codons on mRNA, ensuring the correct amino acid is added to the growing polypeptide chain. C) Carries specific amino acids to the ribosomes: This is the primary role of tRNA in protein synthesis. Each tRNA molecule is specific for a particular amino acid and carries it to the ribosome, where it is added to the growing protein chain. D) Modifies the structure of proteins: This is not a function of tRNA. Protein modification can occur after translation is complete and involves other cellular processes and molecules.

5. Square: A garden bed has a side length of 8 meters. What is its perimeter?

• A. 16m
• B. 24m
• C. 32m
• D. 64m

Correct answer: D

Rationale: Since all sides are equal, multiply the side length by 4: perimeter = 4 * side length = 4 * 8m = 32m.

6. What is the main point of the passage?

• A. Climate change is a myth and does not pose any significant threat to the planet.
• B. The negative consequences of climate change are inevitable and irreversible.
• C. Human actions are the primary cause of climate change, and global efforts are needed to address it.
• D. Technological advancements alone can provide quick and easy solutions to the climate crisis.

Correct answer: C

Rationale: The passage clearly identifies human activities as the cause of climate change and emphasizes the need for global action, aligning with C.
