Biology
1. What is the process of breaking down proteins into amino acids called?
- A. Proteolysis
- B. Lipolysis
- C. Carbohydrate catabolism
- D. Nucleic acid catabolism
Correct answer: A
Rationale: Rationale: Proteolysis is the process of breaking down proteins into amino acids. Lipolysis is the breakdown of fats into fatty acids and glycerol, not proteins. Carbohydrate catabolism involves the breakdown of carbohydrates into glucose for energy production. Nucleic acid catabolism is the breakdown of nucleic acids into nucleotides. In this context, the specific process of breaking down proteins into amino acids is best described by proteolysis.
2. What literary device is used in the phrase "a heart of gold"?
- A. Metaphor
- B. Simile
- C. Hyperbole
- D. Personification
Correct answer: A
Rationale: The phrase directly compares someone's good nature to gold, making it a metaphor.
3. What is the difference between homologous chromosomes and sister chromatids?
- A. Homologous chromosomes have the same genes but may have different alleles, while sister chromatids are identical copies of the same chromosome.
- B. Homologous chromosomes are only found in diploid cells, while sister chromatids are found in both haploid and diploid cells.
- C. Both homologous chromosomes and sister chromatids are genetically identical, but only sister chromatids separate during mitosis.
- D. Both homologous chromosomes and sister chromatids can separate during mitosis, but only homologous chromosomes have different alleles.
Correct answer: A
Rationale: Rationale: - Homologous chromosomes are pairs of chromosomes that have the same genes in the same order, one from each parent. While they carry the same genes, they may have different alleles (variants of a gene). - Sister chromatids are exact copies of each other, formed during DNA replication. They are held together by a centromere and are produced during the S phase of the cell cycle. - During meiosis, homologous chromosomes pair up and exchange genetic material through crossing over, leading to genetic variation. Sister chromatids separate during mitosis to ensure each daughter cell receives an identical copy of the genetic material.
4. Which of the following is a strong base commonly used in cleaning products?
- A. Sodium hydroxide (NaOH)
- B. Ammonium hydroxide (NHâ‚„OH)
- C. Calcium hydroxide (Ca(OH)â‚‚)
- D. Potassium hydroxide (KOH)
Correct answer: A
Rationale: Sodium hydroxide is a strong base commonly used in cleaning products. The other choices are also bases but are not as strong as sodium hydroxide.
5. Which of the following is the main function of the kidneys?
- A. To filter waste products from the blood
- B. To produce urine
- C. To regulate blood pressure
- D. To produce hormones that help to control blood sugar levels
Correct answer: A
Rationale: Rationale: A) To filter waste products from the blood: The main function of the kidneys is to filter waste products, excess ions, and water from the bloodstream to form urine, which is then excreted from the body. This process helps maintain the body's internal environment by regulating the balance of electrolytes, fluid volume, and pH levels. B) To produce urine: While the kidneys do produce urine as a result of filtering the blood, the primary function is to filter waste products rather than solely producing urine. C) To regulate blood pressure: The kidneys do play a role in regulating blood pressure by controlling the volume of blood and the concentration of electrolytes in the body, but their main function is waste filtration. D) To produce hormones that help to control blood sugar levels: While the kidneys do produce hormones like erythropoietin and renin that play a role in various physiological processes, such as red
6. How does an increase in temperature generally affect the solubility of most solid solutes in a liquid solvent?
- A. It increases solubility
- B. It decreases solubility
- C. It has no effect on solubility
- D. It depends on the nature of the solute
Correct answer: a
Rationale: In general, increasing temperature tends to increase the solubility of most solid solutes in liquid solvents. The other choices do not accurately describe the effect of temperature on solubility.
