1. Which of the following phrases is grammatically correct and uses parallel structure?
- A. He enjoys reading, writing, and playing sports.
- B. Walking, swimming, and cooking are his favorite hobbies.
- C. He likes to read, write, and play sports.
- D. Singing, dancing, and traveling are his passions.
Correct answer: B
Rationale: Option B is the correct answer as it uses the gerund (-ing) form for all three hobbies, achieving parallel structure. Parallel structure requires that elements in a sentence are grammatically balanced. In this case, all three activities are presented in the same form, making the sentence clear and consistent. Choices A, C, and D do not exhibit parallel structure as they mix verb forms or use infinitives, breaking the parallelism needed for correct grammar.
2. Which of the following is NOT a greenhouse gas?
- A. Carbon dioxide
- B. Water vapor
- C. Nitrogen
- D. Methane
Correct answer: C
Rationale: Rationale: A) Carbon dioxide: Carbon dioxide is a greenhouse gas that is naturally present in the Earth's atmosphere and is also released through human activities such as burning fossil fuels. B) Water vapor: Water vapor is a greenhouse gas that is naturally present in the atmosphere and plays a significant role in the Earth's climate system. C) Nitrogen: Nitrogen is not considered a greenhouse gas because it does not have the ability to absorb and emit infrared radiation in the same way that greenhouse gases like carbon dioxide and methane do. D) Methane: Methane is a potent greenhouse gas that is released through natural processes such as wetland decomposition and human activities such as livestock farming and fossil fuel extraction. Therefore, the correct answer is C) Nitrogen, as it is not a greenhouse gas.
3. Which structure in the skin is responsible for producing melanin?
- A. Sudoriferous gland
- B. Melanocyte
- C. Sebaceous gland
- D. Hair follicle
Correct answer: B
Rationale: The correct answer is B: Melanocyte. Melanocytes in the skin are responsible for producing melanin, the pigment that gives skin its color and provides protection against harmful UV radiation. Sudoriferous glands produce sweat, sebaceous glands produce sebum (oil), and hair follicles are associated with hair growth. However, the specific function of producing melanin is attributed to melanocytes, making them the correct answer in this context.
4. Describe the mechanism by which genes are transmitted from parents to offspring.
- A. Blending of parental genes, resulting in an average of their traits.
- B. Random assortment of alleles during meiosis, leading to unique combinations in each offspring.
- C. Inheritance of solely dominant alleles, masking the influence of recessive ones.
- D. Direct transfer of both parental genomes, creating identical copies of the parents.
Correct answer: B
Rationale: A) Blending of parental genes, resulting in an average of their traits, is not an accurate description of how genes are transmitted. In reality, genes are not blended but rather passed down in discrete units. B) Random assortment of alleles during meiosis is the correct mechanism by which genes are transmitted from parents to offspring. During meiosis, homologous chromosomes separate, and alleles are randomly distributed to the gametes, leading to unique combinations of genes in each offspring. C) Inheritance of solely dominant alleles, masking the influence of recessive ones, is not an accurate representation of gene transmission. Offspring inherit alleles from both parents, and the expression of dominant or recessive traits depends on the specific combination of alleles. D) Direct transfer of both parental genomes, creating identical copies of the parents, is not how genes are transmitted. Offspring inherit a unique combination
5. Which organelle in the cell is responsible for producing energy in the form of ATP?
- A. Nucleus
- B. Mitochondria
- C. Ribosome
- D. Golgi apparatus
Correct answer: B
Rationale: The correct answer is B: Mitochondria. Mitochondria are known as the powerhouses of the cell and are responsible for producing energy in the form of ATP through cellular respiration. ATP is the primary energy currency of the cell, powering various cellular activities. The nucleus (choice A) is responsible for housing the cell's genetic material but is not involved in ATP production. Ribosomes (choice C) are involved in protein synthesis, not energy production. The Golgi apparatus (choice D) is responsible for modifying, sorting, and packaging proteins for secretion, not for ATP production.
