1. What property of a substance refers to its ability to be drawn into thin wires without breaking?

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

Correct answer: c

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

2. What kind of bond links amino acids together?

• A. Hydrogen bond
• B. Ionic bond
• C. Disulfide bond
• D. Covalent bond

Correct answer: D

Rationale: Rationale: Amino acids are linked together by covalent bonds to form proteins. A covalent bond is a strong chemical bond formed by the sharing of electrons between atoms. In the case of amino acids, the covalent bond that links them together is called a peptide bond. This bond forms between the amino group of one amino acid and the carboxyl group of another amino acid, resulting in the formation of a peptide chain. Hydrogen bonds, ionic bonds, and disulfide bonds can also play roles in protein structure and stability, but the primary bond linking amino acids together in a protein chain is the covalent peptide bond.

3. Which type of orbital can hold a maximum of 10 electrons?

• A. s orbital
• B. p orbital
• C. d orbital
• D. f orbital

Correct answer: D

Rationale: Each f orbital can hold up to 2 electrons, and there are 5 f orbitals, totaling a maximum of 10 electrons.

4. What is the main topic of the passage?

• A. Benefits of bioremediation in cleaning oil spills.
• B. Dangers of microplastics to marine ecosystems.
• C. History of plastic production and its global impact.
• D. Comparison of different waste management strategies.

Correct answer: B

Rationale: The passage focuses on the specific issue of microplastics in the marine environment and their harmful effects.

5. What happens to the frequency of a wave if its wavelength decreases while the speed remains constant?

• A. Frequency decreases
• B. Frequency increases
• C. Frequency remains constant
• D. Frequency becomes zero

Correct answer: b

Rationale: If the speed of the wave remains constant while the wavelength decreases, the frequency of the wave increases.

6. Which test is commonly used to assess kidney function?

• A. Complete blood count (CBC)
• B. Blood sugar test
• C. Urinalysis
• D. Creatinine clearance test

Correct answer: D

Rationale: The correct answer is D: Creatinine clearance test. This test is commonly used to assess kidney function by measuring how well the kidneys are filtering waste products like creatinine from the blood. Creatinine is a waste product produced by muscles and is normally filtered out by the kidneys. A high level of creatinine in the blood can indicate reduced kidney function. Options A, B, and C are not specifically used to assess kidney function. A complete blood count (CBC) measures different components of the blood like red blood cells, white blood cells, and platelets. A blood sugar test is used to measure glucose levels in the blood. Urinalysis is a test that analyzes the urine for various substances like proteins, glucose, and blood cells, but it is not the primary test for assessing kidney function.
