Mathematics

1. 12 is a/an:

Correct answer: A

Rationale: Even numbers are integers divisible by 2 without a remainder. Since 12 divided by 2 equals 6 with no remainder, 12 is even.

2. Which factor affects the gravitational potential energy of an object the most?

Correct answer: B

Rationale: Gravitational potential energy is directly proportional to the height or distance from the ground. As the object is raised higher, its gravitational potential energy increases. The mass of the object affects the gravitational potential energy, but the distance from the ground has a greater impact on it. The gravitational force and the shape of the object do not directly affect the gravitational potential energy.

3. Which of the following best describes a balanced force acting on an object?

Correct answer: b

Rationale: When balanced forces act on an object, the object remains in a state of constant velocity (including at rest).

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

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. Which energy transformation occurs when a guitar string vibrates to produce sound?

Correct answer: c

Rationale: The electrical energy in the guitar's amplifier is converted into sound energy when the string vibrates.

6. The pancreas releases a number of digestive enzymes into the small intestine. Which of the following enzymes is NOT produced by the pancreas?

Correct answer: B

Rationale: The correct answer is B: Amylase (carbohydrate digestion). The pancreas produces digestive enzymes that aid in breaking down food components. Trypsin is produced by the pancreas for protein digestion, lipase for fat digestion, and lactase is an enzyme produced in the small intestine for breaking down lactose (sugar). Amylase, on the other hand, is primarily produced in the salivary glands and the pancreas to break down carbohydrates into simple sugars. Therefore, amylase is not a pancreatic enzyme for digestion, making it the correct answer in this question.
