Question 1 of 5

Which of the following is a function of the kidneys?

Correct Answer: B

Rationale: The correct answer is B: To filter waste from the blood. The kidneys play a crucial role in filtering waste products, excess substances, and toxins from the blood to form urine. This process helps maintain the body's overall balance of fluids and electrolytes. Choices A, C, and D are incorrect as the kidneys do not produce digestive enzymes (A), white blood cells (C), or red blood cells (D). The primary function of the kidneys is to regulate fluid and electrolyte balance, remove waste products, and help control blood pressure.

Question 2 of 5

Which of the following is an example of a ball-and-socket joint?

Correct Answer: B

Rationale: The correct answer is B: Hip. A ball-and-socket joint allows for a wide range of motion in multiple directions. The hip joint fits this description, with the rounded head of the femur fitting into the socket of the pelvis. This joint enables movements like flexion, extension, abduction, adduction, and rotation. The other choices, such as the knee (A), elbow (C), and wrist (D), are not ball-and-socket joints. The knee is a hinge joint, the elbow is a hinge joint as well, and the wrist is a condyloid joint.

Question 3 of 5

Which of the following are examples of positive correlation?

Correct Answer: D

Rationale: The correct answer is D because a positive correlation indicates that as one variable increases, the other variable also increases. In this case, when plotting rainfall against plant length, if the line trends to the upper right, it shows that as rainfall increases, the plant length also increases. This demonstrates a positive correlation. A is incorrect because it describes a negative correlation where an increase in rainfall leads to a decrease in plant stem length. B is incorrect as it suggests a positive correlation between rainfall and roots length. C is incorrect as a line trending to the lower right also indicates a negative correlation between the variables.

Question 4 of 5

Which organ stores and concentrates bile?

Correct Answer: B

Rationale: The correct answer is B: Gallbladder. The gallbladder stores and concentrates bile produced by the liver, releasing it into the small intestine to aid in digestion. The liver produces bile but does not store it. The pancreas produces digestive enzymes, not bile. The stomach produces gastric juices for digestion, not bile.

Question 5 of 5

What is the ultimate end product of glucose breakdown in glycolysis?

Correct Answer: C

Rationale: The correct answer is C: Pyruvic acid. In glycolysis, glucose is broken down into pyruvic acid. This process involves a series of enzymatic reactions that result in the production of pyruvic acid, which is a crucial intermediate in cellular respiration. Pyruvic acid can then enter the citric acid cycle to further extract energy in the form of ATP. Rationale for other choices: A: ATP is produced during glycolysis, but it is not the end product. B: NADPH is not the end product of glucose breakdown in glycolysis; it is a reducing agent used in various metabolic pathways. D: Oxygen is not directly produced as a result of glucose breakdown in glycolysis; oxygen is utilized in later stages of cellular respiration.
