Correct Answer: A

Rationale: Failed to generate a rationale after 5 retries.

Correct Answer: D

Rationale: The correct answer is D: Solar energy to electrical energy. Solar cells, also known as photovoltaic cells, convert sunlight (solar energy) directly into electricity through the photovoltaic effect. When sunlight hits the solar cell, photons from the sunlight are absorbed by the semiconducting material in the cell, creating an electric current. This process allows solar cells to generate electricity without moving parts or the need for any other energy sources. Explanation for other choices: A: Electrical energy to light energy - This is incorrect as solar cells do not convert electrical energy into light energy, but rather convert solar energy into electrical energy. B: Chemical energy to electrical energy - This is incorrect as solar cells do not involve any chemical reactions to produce electricity. C: Solar energy to thermal energy - This is incorrect as solar cells are designed to convert solar energy directly into electrical energy, not thermal energy.

Correct Answer: D

Rationale: The correct answer is D: Influenza. Influenza is caused by a virus, specifically the influenza virus. Step-by-step rationale: 1. Influenza is a contagious respiratory illness caused by the influenza virus. 2. Viruses are known to be the causative agents of influenza. 3. Asthma (A), Cystic Fibrosis (B), and Epiglottitis (C) are not caused by viruses; asthma is a chronic inflammatory disease, cystic fibrosis is a genetic disorder, and epiglottitis is usually caused by bacteria.

Correct Answer: D

Rationale: The correct answer is D: Tensile strength. Dense irregular connective tissue, found in tendons and ligaments, is composed of collagen fibers arranged in a random pattern, providing resistance to tension in multiple directions. This structural arrangement allows tendons and ligaments to withstand pulling forces and maintain their shape, ultimately providing tensile strength. Explanation: A: Flexibility - While tendons and ligaments do require some degree of flexibility, their primary function is to provide strength and stability rather than flexibility. B: Lubrication - Lubrication is not a primary function of dense irregular connective tissue in tendons and ligaments. C: Insulation - Dense irregular connective tissue does not primarily serve as an insulating material in tendons and ligaments; its main function is to provide mechanical support and strength. In summary, the correct answer is D because dense irregular connective tissue in tendons and ligaments is specifically designed to provide tensile strength by resisting pulling forces and

Correct Answer: B

Rationale: The correct answer is B. A decomposition reaction involves a single compound breaking down into two or more simpler substances. In choice B, CaCO3 decomposes into CaO and CO2. This reaction follows the general form AB → A + B, making it a clear example of a decomposition reaction. Choices A, C, and D involve synthesis or combination reactions, where simpler substances combine to form a more complex compound, making them incorrect for this question.
