ATI TEAS 7 science review

1. How are kidney stones formed?

Correct answer: B

Rationale: Kidney stones are formed when minerals in the urine crystallize and stick together to form solid masses. Excess water not being reabsorbed (option A) does not directly contribute to kidney stone formation. Similarly, electrolytes becoming too concentrated (option C) is not a direct cause of kidney stone formation. The correct answer is B because the crystallization of minerals in the urine leads to the formation of kidney stones.

2. Which organ in the human body is responsible for filtering blood and producing urine?

Correct answer: B

Rationale: The correct answer is B: Kidneys. The kidneys are vital organs in the human body responsible for filtering blood to remove waste products and excess substances, producing urine as a result. The liver plays a role in detoxification and metabolism. The pancreas is involved in digestion and blood sugar regulation. The heart pumps blood throughout the body but does not filter blood or produce urine.

3. Which factor affects the gravitational potential energy of an object the most?

Correct answer: B

Rationale: Gravitational potential energy is directly proportional to the height or distance from the ground. As the object is raised higher, its gravitational potential energy increases. While the mass of the object influences gravitational potential energy, the distance from the ground has a more significant impact on it. The gravitational force does not directly affect the gravitational potential energy; it is the force that causes the potential energy to change with height. The shape of the object also does not determine gravitational potential energy, as it is primarily determined by the object's position in a gravitational field.

4. What is the term for the particles moving within a substance?

Correct answer: C

Rationale: The term for the particles moving within a substance is typically 'molecules' or 'atoms,' depending on the state of matter. In this context, 'molecules' represent the particles moving around within a substance, especially in the liquid and gas states, while 'atoms' are the fundamental building blocks of matter. 'Ions' are charged particles that can be present in a substance but are not necessarily the primary particles in motion. 'Kinetic energy' is not a term used to describe the particles themselves but rather the energy associated with their motion.

5. Which property describes a substance's resistance to flow?

Correct answer: B

Rationale: Viscosity is the property that describes a substance's resistance to flow. A substance with high viscosity flows slowly, while a substance with low viscosity flows quickly. Density (A) is the measure of mass per unit volume; conductivity (C) is the ability of a material to conduct electricity or heat, and reactivity (D) refers to how readily a substance undergoes chemical reactions. Therefore, the correct answer is B, viscosity, as it directly relates to a substance's resistance to flow.
