1. What is the main function of energy storage technologies in the context of renewable energy?
- A. Reduce the cost of producing solar and wind power.
- B. Enhance the efficiency of energy transmission and distribution.
- C. Compensate for the intermittent nature of renewable energy sources.
- D. Eliminate the need for fossil fuels in electricity generation.
Correct answer: C
Rationale: Choice C directly addresses the passage's emphasis on managing the fluctuating availability of renewable energy, hence being the main function of storage technologies.
2. The stratified squamous epithelium found in the skin is adapted for:
- A. Absorption
- B. Secretion
- C. Protection
- D. Gas exchange
Correct answer: C
Rationale: The correct answer is C: Protection. Stratified squamous epithelium is a type of tissue that is well-suited for protection as it consists of multiple layers of cells that provide a barrier against physical and chemical damage. In the skin, this epithelium helps protect the body against external threats such as pathogens, UV radiation, and mechanical abrasion. Absorption (A) and secretion (B) are typically functions of other types of epithelial tissues, such as simple columnar or simple cuboidal epithelium. Gas exchange (D) is primarily facilitated by tissues like the alveolar epithelium in the lungs, not stratified squamous epithelium in the skin.
3. What is the end result of mitosis in animal cells?
- A. The production of two identical daughter cells
- B. The production of four haploid cells
- C. The production of a single diploid cell
- D. The production of a single haploid cell
Correct answer: A
Rationale: Rationale: Mitosis is a type of cell division that results in the production of two identical daughter cells, each having the same number of chromosomes as the parent cell. This process is essential for growth, repair, and maintenance of multicellular organisms. During mitosis, the replicated chromosomes are separated into two nuclei, and the cell then divides to form two genetically identical daughter cells. Options B, C, and D are incorrect because mitosis does not result in the production of four haploid cells, a single diploid cell, or a single haploid cell.
4. The adaptive immune system develops a targeted response to specific pathogens. What type of immune cell is responsible for producing antibodies?
- A. Natural killer cells
- B. Phagocytes
- C. Helper T cells
- D. B cells
Correct answer: D
Rationale: The correct answer is D: B cells. B cells are a type of lymphocyte responsible for producing antibodies, which play a crucial role in the adaptive immune response. When a pathogen enters the body, B cells are activated and differentiate into plasma cells that secrete specific antibodies to target and neutralize the pathogen. Natural killer cells (A) are part of the innate immune system and are responsible for killing infected or abnormal cells. Phagocytes (B) are another type of innate immune cell that engulfs and digests pathogens. Helper T cells (C) play a vital role in coordinating the immune response but do not directly produce antibodies.
5. How does an increase in surface area affect the force of friction between two surfaces?
- A. Increases friction
- B. Decreases friction
- C. Has no effect on friction
- D. Causes unpredictable changes in friction
Correct answer: b
Rationale: Increasing surface area reduces the force per unit area, decreasing friction.
6. What is the best way to revise the sentence: "Her eyes glistened with tears in the moonlight"?
- A. Her eyes glistened in the moonlight, with tears.
- B. Tears glistened in her eyes with moonlight.
- C. Her eyes, in the moonlight, glistened with tears.
- D. Tears made her eyes glisten in the moonlight.
Correct answer: C
Rationale: Option C rearranges the elements for smoother flow and emphasis on the tears.
