1. What is the scientific study of the relationships between organisms and their environment?

Correct answer: C

Rationale: Ecology is the scientific study of the relationships between organisms and their environment, including the interactions between living organisms and their physical surroundings. This field focuses on how organisms interact with each other and their environment. Zoology is the study of animals, Botany is the study of plants, and Genetics is the study of genes and heredity, which are not directly related to the relationships between organisms and their environment. Therefore, the correct answer is Ecology as it specifically deals with the interactions between living organisms and their environment.

2. A ball is rolling across the floor and comes to a stop on its own. What force caused the ball to stop?

Correct answer: C

Rationale: The force that caused the ball to stop rolling across the floor is air resistance. As the ball moves through the air, air resistance acts in the opposite direction of its motion, gradually slowing it down until it comes to a stop. In this scenario, the ball is not in contact with the floor, so the normal force from the floor does not play a role in stopping the ball. Gravitational force acts to pull objects towards the center of the Earth and would not directly stop the ball in this situation. Therefore, air resistance is the force that opposes the motion of the rolling ball and causes it to come to a stop.

3. Which of the following factors does NOT affect the rate of dissolution of a solute in a solvent?

Correct answer: B

Rationale: Pressure does not affect the rate of dissolution of a solute in a solvent. The factors that affect the rate of dissolution include temperature, surface area, and particle size. Temperature generally increases the rate of dissolution by providing more energy for the solute particles to break apart and mix with the solvent. Increasing the surface area of the solute by grinding it into smaller particles or increasing its contact area with the solvent can also speed up dissolution. Similarly, reducing the particle size of the solute can increase the rate of dissolution by providing more surface area for interaction with the solvent. Pressure, however, does not have a significant impact on the dissolution process and is not a factor that influences the rate at which a solute dissolves in a solvent.

4. When a car brakes to a stop, friction between the tires and the road acts as:

Correct answer: B

Rationale: When a car brakes to a stop, friction between the tires and the road acts as an unbalanced force causing deceleration. This friction force opposes the motion of the car, resulting in a decrease in speed until the car comes to a complete stop. Choice A is incorrect because if the forces were balanced, the car would not experience any deceleration. Choice C is incorrect because if the force were unbalanced in the direction of motion, the car would continue to move instead of coming to a stop. Choice D is incorrect because friction between the tires and the road does exert a force, causing deceleration.

5. What is a benefit of a taxonomic system?

Correct answer: D

Rationale: The correct answer is D. A taxonomic system allows scientists to classify living organisms based on their molecular and genetic traits. This classification helps in understanding the relationships and evolutionary history of different organisms, providing insights into their characteristics and behaviors. Choices A, B, and C do not directly relate to the primary purpose and benefit of a taxonomic system, which is the systematic classification of organisms.
