Correct Answer: A

Rationale: The correct answer is A: Hydrogen gas and sodium chloride (NaCl). When NaOH reacts with HCl, a neutralization reaction occurs, forming water and a salt. NaOH + HCl -> NaCl + H2O. Sodium chloride and water are the products formed in this reaction. Hydrogen gas is also produced as a byproduct. Choices B, C, and D are incorrect as they do not represent the correct products of the reaction based on the chemical equation.

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.

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: B

Rationale: The correct answer is B: Edema. Edema is the condition characterized by swelling caused by a buildup of lymph fluid. Lymph fluid can accumulate in tissues due to various reasons such as lymphatic system blockages or underlying medical conditions. Anemia (A) is a condition characterized by a deficiency of red blood cells or hemoglobin. Hypertension (C) is high blood pressure, not related to lymph fluid buildup. Diabetes (D) is a metabolic disorder affecting blood sugar levels, not directly related to lymph fluid accumulation. In this case, edema is the most appropriate choice as it specifically addresses the swelling caused by lymph fluid buildup.

Correct Answer: C

Rationale: The correct answer is C: Isotonic solution. An isotonic solution has the same concentration of solute as another solution, leading to no net movement of water across a semipermeable membrane. This term is commonly used in biology and medicine to describe solutions with equal osmotic pressure. Incorrect answers: A: Saturated solution - A saturated solution is one in which the maximum amount of solute has been dissolved at a given temperature. B: Unsaturated solution - An unsaturated solution has a lower concentration of solute compared to what it could dissolve at a given temperature. D: Concentrated solution - A concentrated solution simply means a solution with a high amount of solute dissolved in a solvent, but it does not necessarily mean it has the same concentration as another solution.
