Biology
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 of the following sentences uses the most formal language?
- A. The movie was awesome!
- B. The film did not meet my expectations.
- C. I found the cinematic experience to be unsatisfactory.
- D. The flick was pretty bad.
Correct answer: C
Rationale: The sentence uses more complex vocabulary ("cinematic experience") and avoids slang ("awesome," "flick").
3. What is an example of a fibrous protein?
- A. Insulin
- B. Keratin
- C. Hemoglobin
- D. Collagen
Correct answer: D
Rationale: Rationale: A) Insulin is a hormone, not a fibrous protein. Insulin is produced in the pancreas and is involved in regulating blood sugar levels. B) Keratin is a fibrous structural protein found in hair, nails, and the outer layer of skin. It provides strength and protection. C) Hemoglobin is a globular protein found in red blood cells that is responsible for carrying oxygen from the lungs to the rest of the body. It is not a fibrous protein. D) Collagen is a fibrous protein that is the main component of connective tissues such as tendons, ligaments, and skin. It provides strength and structure to these tissues.
4. In which part of the cell are proteins modified, sorted, and packaged for transport?
- A. Ribosomes
- B. Golgi apparatus
- C. Endoplasmic reticulum (ER)
- D. Lysosomes
Correct answer: B
Rationale: The Golgi apparatus is responsible for modifying, sorting, and packaging proteins for transport. After proteins are synthesized in the rough endoplasmic reticulum (ER), they are transported to the Golgi apparatus where they undergo post-translational modifications and are sorted into vesicles for transport to their final destinations. Ribosomes are responsible for protein synthesis, the endoplasmic reticulum is involved in protein synthesis and folding, and lysosomes are responsible for digesting cellular waste. Therefore, the correct answer is B, Golgi apparatus, as it is specifically involved in the modification, sorting, and packaging of proteins for transport.
5. A new invention claims to solve the energy crisis. What criteria should you use to evaluate this claim?
- A. The inventor's qualifications and credentials.
- B. The technology's cost-effectiveness and affordability.
- C. Evidence of independent testing and scientific validation.
- D. Testimonials from celebrities and public figures.
Correct answer: C
Rationale: When evaluating a claim about solving the energy crisis, it is crucial to look for evidence of independent testing and scientific validation. This ensures that the technology has been rigorously assessed and verified by experts in the field, providing credibility to the invention's effectiveness. Testimonials from celebrities and public figures (option D) may not provide reliable information about the technology's actual capabilities. The inventor's qualifications and credentials (option A) are important but do not guarantee the technology's success. Cost-effectiveness and affordability (option B) are significant factors but should be considered alongside scientific validation to assess the overall impact and feasibility of the invention.
6. When choosing a color palette for a presentation, it's best to:
- A. Use as many vibrant colors as possible to grab attention.
- B. Stick to a monochrome palette for a minimalist look
- C. Select complementary colors that create harmony and contrast.
- D. Use the same colors as your company logo for consistency.
Correct answer: C
Rationale: While both branding consistency and minimalism have their place, presentations benefit from utilizing complementary colors for visual interest and clarity.
