Question 3 of 5
Which organ in the body is responsible for maintaining electrolyte balance and filtering waste from the blood?
Correct Answer: B
Rationale: The correct answer is B: Kidneys. The kidneys are responsible for maintaining electrolyte balance through processes like reabsorption and excretion. They also filter waste from the blood to form urine. The liver primarily processes nutrients and detoxifies substances. The heart is responsible for pumping blood, not filtering waste. The lungs are involved in gas exchange, not electrolyte balance or waste filtration. Therefore, the kidneys are the correct choice for this function.
Question 4 of 5
What is the role of the pancreas in the digestive system?
Correct Answer: B
Rationale: The correct answer is B: To secrete digestive enzymes. The pancreas secretes enzymes such as amylase, lipase, and proteases that help break down carbohydrates, fats, and proteins in the small intestine. This aids in the digestion and absorption of nutrients. Storing bile (A) is the role of the gallbladder, digesting proteins (C) is primarily done by the stomach and small intestine, and absorbing nutrients (D) mainly occurs in the small intestine.
Question 5 of 5
Which property of matter refers to the amount of space occupied by an object and is measured in cubic units?
Correct Answer: D
Rationale: The correct answer is D: Volume. Volume refers to the amount of space occupied by an object and is measured in cubic units. It is calculated by multiplying the length, width, and height of an object. Mass (A) is the amount of matter in an object, density (B) is the mass per unit volume, and weight (C) is the force of gravity acting on an object. Therefore, Volume is the only property that directly relates to the amount of space occupied by an object, making it the correct answer.
