1. What is the building block of RNA?

• A. Amino acid
• B. Nucleotide
• C. Protein
• D. Fatty acid

Correct answer: B

Rationale: Rationale: A) Amino acid: Amino acids are the building blocks of proteins, not RNA. B) Nucleotide: Nucleotides are the building blocks of RNA. A nucleotide consists of a nitrogenous base (adenine, guanine, cytosine, or uracil in RNA), a sugar (ribose in RNA), and a phosphate group. C) Protein: Proteins are made up of amino acids, not nucleotides. D) Fatty acid: Fatty acids are components of lipids, not RNA.

2. Which property of a substance refers to its ability to be stretched into thin wires without breaking?

• A. Conductivity
• B. Viscosity
• C. Ductility
• D. Malleability

Correct answer: c

Rationale: Ductility is the property that describes a substance's ability to be stretched into thin wires without breaking.

3. What is the term for the particles moving around within a substance?

• A. Ions
• B. Atoms
• C. Molecules
• D. Kinetic energy

Correct answer: C

Rationale: In most cases, the particles moving within a substance are individual molecules or atoms, depending on the state of matter.

4. Based on the passage, which statement is MOST likely to be true about the author's stance on social media?

• A. It should be completely banned due to its overwhelmingly negative impact.
• B. It can be a valuable tool but needs stricter regulations to address emerging issues.
• C. Its benefits outweigh its drawbacks, and concerns about its use are exaggerated.
• D. Technology alone cannot solve the problems associated with social media use.

Correct answer: B

Rationale: The emphasis on critical thinking and responsible online behavior suggests an acknowledgment of social media's potential while advocating for addressing its downsides, aligning with B.

5. What is the breakdown product of ATP (adenosine triphosphate) that provides energy for muscle contraction?

• A. Glucose
• B. Creatine phosphate
• C. ADP (adenosine diphosphate)
• D. Lactic acid

Correct answer: C

Rationale: The correct answer is C: ADP (adenosine diphosphate). During muscle contraction, ATP is broken down into ADP and inorganic phosphate, releasing energy that fuels the muscle contraction process. This energy release allows the muscle fibers to contract and perform work. Glucose is a source of energy that is broken down through cellular respiration to produce ATP but is not the direct breakdown product of ATP itself. Creatine phosphate is another energy storage molecule in muscles but is not the breakdown product of ATP. Lactic acid is produced during anaerobic respiration when there is a lack of oxygen, and it is not the primary energy source for muscle contraction. Therefore, ADP is the correct breakdown product of ATP that provides energy for muscle contraction.

6. Which part of the male urinary system is responsible for producing seminal fluid?

• A. Bladder
• B. Urethra
• C. Prostate gland
• D. Kidney

Correct answer: C

Rationale: The correct answer is C: Prostate gland. The prostate gland is responsible for producing seminal fluid, which is a milky fluid that nourishes and protects sperm. The bladder stores urine, the urethra is a tube that carries urine from the bladder out of the body, and the kidney filters waste products from the blood to produce urine. The prostate gland, located beneath the bladder, plays a crucial role in male reproductive health by contributing to semen production. Understanding the functions of each part of the male urinary system is important for comprehending reproductive anatomy and physiology.
