1. Which of the following numbers is NOT divisible by 3?
- A. 105
- B. 141
- C. 273
- D. 810
Correct answer: D
Rationale: Rationale: To determine if a number is divisible by 3, we can check if the sum of its digits is divisible by 3. If the sum of the digits is divisible by 3, then the original number is also divisible by 3. A) 105: 1 + 0 + 5 = 6, which is divisible by 3. Therefore, 105 is divisible by 3. B) 141: 1 + 4 + 1 = 6, which is divisible by 3. Therefore, 141 is divisible by 3. C) 273: 2 + 7 + 3 = 12, which is divisible by 3. Therefore, 273 is divisible by 3. D) 810: 8 + 1 + 0 = 9, which is divisible by 3. Therefore, 810 is divisible by 3. Since all the
2. What are the three main types of RNA?
- A. Messenger RNA (mRNA), ribosomal RNA (rRNA), and transfer RNA (tRNA)
- B. DNA, RNA, and protein
- C. Adenine, guanine, cytosine, and thymine
- D. Deoxyribose, ribose, and phosphate
Correct answer: A
Rationale: Rationale: - Messenger RNA (mRNA) carries genetic information from the DNA in the nucleus to the ribosomes in the cytoplasm for protein synthesis. - Ribosomal RNA (rRNA) is a structural component of ribosomes, which are the cellular machinery responsible for protein synthesis. - Transfer RNA (tRNA) is responsible for bringing amino acids to the ribosome during protein synthesis. Options B, C, and D are incorrect: - Option B lists DNA, RNA, and protein, which are biomolecules but not the three main types of RNA. - Option C lists nitrogenous bases (adenine, guanine, cytosine, and thymine) found in DNA, not types of RNA. - Option D lists components of nucleotides (deoxyribose, ribose, and phosphate), which are building blocks of nucleic
3. 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.
4. What is the building block of DNA?
- A. Amino acid
- B. Nucleotide
- C. Nucleotide
- D. Fatty acid
Correct answer: B
Rationale: Rationale: - Amino acids are the building blocks of proteins, not DNA. - Nucleotide is the correct building block of DNA. A nucleotide consists of a sugar (deoxyribose in DNA), a phosphate group, and a nitrogenous base (adenine, thymine, cytosine, or guanine). - The option "C) Nucleotide" is a duplicate of the correct answer "B) Nucleotide." - Fatty acids are not the building blocks of DNA; they are a type of lipid molecule.
5. He wants to influence the customary way of thinking and behaving that is shared by the
- A. Organizational chart
- B. Cultural network
- C. Organizational structure
- D. Organizational culture
Correct answer: A
Rationale: The correct answer is A: "Organizational chart." In the context of the question, the individual is aiming to impact the established patterns of thinking and behavior within a group or organization. An organizational chart typically depicts the formal structure of an organization, including roles, relationships, and reporting lines. By influencing the organizational chart, the individual can potentially shape the hierarchical structure and decision-making processes, thereby impacting the customary way of thinking and behaving within the organization. Options B, C, and D do not directly refer to the visual representation of roles and relationships within an organization, making them incorrect choices for this question.
6. What does the term "colligative property" refer to in solutions?
- A. Properties that depend on the nature of the solute particles
- B. Properties that depend on the concentration of solute particles
- C. Properties that depend on the temperature of the solution
- D. Properties that depend on the pressure of the solution
Correct answer: b
Rationale: Colligative properties are dependent on the number of solute particles in a solution, not their nature. The other choices do not accurately define colligative properties.
