Correct Answer: B

Rationale: The correct answer is B: The angle of the incline. The acceleration of a ball rolling down an inclined plane is primarily determined by the angle of the incline. A steeper incline will result in a greater component of the gravitational force acting parallel to the incline, leading to a higher acceleration. The material of the ball (choice A) does not affect the acceleration in this scenario. Air resistance (choice C) may have a small impact but is usually negligible for small objects like balls. The ball's initial velocity (choice D) does not affect the acceleration once the ball is released from rest on the incline.

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: D

Rationale: The correct answer is D: Trachea. The trachea is the largest part of the airway. It is a tube that connects the larynx to the bronchi, allowing air to pass into and out of the lungs. The trachea is larger than the bronchi, bronchioles, and alveoli. Alveoli are tiny air sacs in the lungs where gas exchange occurs. Bronchi are the main air passages into the lungs, branching off from the trachea. Bronchioles are smaller branches of the bronchi. Therefore, the trachea is the largest structure among the given choices, making it the correct answer.

Correct Answer: C

Rationale: Step 1: Amphiprotic substances can donate and accept protons, making them capable of acting as both acids and bases. Step 2: When amphiprotic substances react, they can donate or accept protons depending on the reaction conditions. Step 3: This ability allows them to exhibit properties of both acids and bases. Step 4: Therefore, Choice C is correct as it accurately describes the nature of amphiprotic substances. Summary: A: Incorrect - Amphiprotic substances can react with both acids and bases, not just acids. B: Incorrect - Amphiprotic substances can react with both acids and bases, not just bases. D: Incorrect - Amphiprotic substances are not inert; they actively participate in chemical reactions by donating and accepting protons.

Correct Answer: B

Rationale: The correct answer is B (25 grams) as the recommended daily fiber intake for adults by the American Heart Association is 25-30 grams. Fiber helps with digestion, heart health, and weight management. Option A (10 grams) is too low and insufficient for daily needs. Option C (35 grams) and D (50 grams) are excessive and may lead to digestive issues like bloating or gas. Therefore, B is the most appropriate choice for optimal health benefits.
