1. What is the recommended daily fiber intake for adults?

• A. 10 grams
• B. 25 grams
• C. 35 grams
• D. 50 grams

Correct answer: B

Rationale: Rationale: The recommended daily fiber intake for adults is around 25 grams for women and 38 grams for men. Fiber is essential for maintaining a healthy digestive system, preventing constipation, and reducing the risk of chronic diseases such as heart disease and diabetes. Consuming an adequate amount of fiber can also help with weight management and promote overall well-being. Therefore, option B is the most appropriate answer based on the recommended daily intake guidelines for adults.

2. The number of protons in the nucleus of an atom determines its:

• A. Mass number
• B. Atomic number
• C. Isotope
• D. Valence electron count

Correct answer: B

Rationale: The atomic number (Z) equals the number of protons in the nucleus and uniquely identifies an element. Mass number (A) includes both protons and neutrons, isotopes have different neutron numbers, and valence electrons are involved in bonding, not atomic identity.

3. 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.

4. What cellular process ensures accurate transmission of genetic material during cell division?

• A. Mitosis (somatic cell division)
• B. Meiosis (germ cell division)
• C. Replication (DNA duplication)
• D. Transcription (DNA to RNA conversion)

Correct answer: A

Rationale: Rationale: A) Mitosis is the process by which somatic cells divide to produce two identical daughter cells. During mitosis, the genetic material is accurately replicated and distributed to ensure each daughter cell receives a complete set of chromosomes. This process is crucial for growth, repair, and maintenance of multicellular organisms. B) Meiosis is the type of cell division that occurs in germ cells to produce gametes (sperm and egg cells). While meiosis also involves the transmission of genetic material, it is specifically geared towards generating genetic diversity through recombination and reduction of chromosome number. C) Replication is the process of copying DNA to produce an identical copy. While replication is essential for cell division, it is not the specific process that ensures accurate transmission of genetic material during cell division. D) Transcription is the process by which genetic information in DNA is copied into RNA. Transcription is important for gene ex

5. The phrase "a bold new world" is an example of

• A. Hyperbole
• B. Oxymoron
• C. Simile
• D. Metaphor

Correct answer: B

Rationale: An oxymoron combines contradictory terms, like "bold new" signifying the unexpected and promising nature of the world.

6. What is the difference between mitosis and meiosis?

• A. Mitosis produces haploid cells, while meiosis produces diploid cells
• B. Mitosis involves crossing over, while meiosis does not.
• C. Mitosis results in four daughter cells, while meiosis results in two
• D. Mitosis is responsible for sexual reproduction, while meiosis is responsible for asexual reproduction.

Correct answer: C

Rationale: Rationale: - Mitosis is a type of cell division that results in two identical daughter cells with the same number of chromosomes as the parent cell. Therefore, mitosis results in two daughter cells. - Meiosis is a type of cell division that results in four daughter cells, each with half the number of chromosomes as the parent cell. This reduction in chromosome number is essential for sexual reproduction. - Option A is incorrect because mitosis produces diploid cells (cells with the same number of chromosomes as the parent cell), while meiosis produces haploid cells (cells with half the number of chromosomes as the parent cell). - Option B is incorrect because crossing over, the exchange of genetic material between homologous chromosomes, occurs during meiosis and not during mitosis. - Option D is incorrect because mitosis is not responsible for sexual reproduction; it is a process of asexual reproduction and
