ATI TEAS Practice Test Science Questions

Question 1 of 5

Which part of the brain is responsible for coordinating voluntary muscle movements?

Correct Answer: B

Rationale: The cerebellum is responsible for coordinating voluntary muscle movements. It plays a crucial role in motor control, helping to maintain balance, posture, and coordination of voluntary movements. The medulla oblongata is involved in regulating basic life functions such as breathing and heart rate. The thalamus serves as a relay center for sensory information, while the hypothalamus is primarily involved in regulating various physiological processes like body temperature, hunger, and thirst. Hence, the correct answer is the cerebellum as it is specifically associated with voluntary muscle coordination, unlike the other brain regions listed.

Question 2 of 5

Which of the following organs is responsible for filtering waste from the blood?

Correct Answer: B

Rationale: The correct answer is B: Kidneys. The kidneys play a vital role in filtering waste from the blood, regulating fluid and electrolyte balance in the body. The liver is involved in detoxification and metabolism, while the pancreas aids in digestion and blood sugar regulation. The heart is responsible for pumping blood throughout the body and does not directly filter waste from the blood.

Question 3 of 5

Which of the following is best identified as a hypothesis?

Correct Answer: A

Rationale: Choice A is the best example of a hypothesis as it presents a testable statement regarding the impact of environmental temperature on plant root growth. A hypothesis should be specific and capable of being tested through experimentation, which is demonstrated in choice A. Choice B is a general statement rather than a testable hypothesis. Choice C lacks specificity and does not clearly state a cause-and-effect relationship to be tested. Choice D provides a specific time frame but does not address a relationship that can be tested through experimentation, making it less suitable as a hypothesis compared to choice A.

Question 4 of 5

An FBI agent has spent her career studying individual serial killers. From this data, she creates a theory about the traits of these killers. What type of reasoning has she used?

Correct Answer: D

Rationale: The correct answer is D: Inductive Reasoning. Inductive reasoning involves drawing a general conclusion from specific observations or data, which fits the scenario described where the FBI agent has studied individual serial killers and formulated a theory about their traits based on this specific data. Deductive reasoning (choice A) starts with general information and applies it to a specific case, which is not the case here. Conductive reasoning (choice B) and quantitative reasoning (choice C) are not relevant to the scenario provided.

Question 5 of 5

What is hydroxyapatite?

Correct Answer: A

Rationale: Hydroxyapatite is a mineral compound composed of calcium and phosphorus that plays a crucial role in strengthening the collagen matrix of bones, contributing to their structural integrity and hardness. It is a key component of bone tissue and provides the mineralization necessary for bone strength and density. Choice B is incorrect because the structural unit of a bone is the osteon or Haversian system, not hydroxyapatite. Choice C is incorrect as it describes cartilage, not hydroxyapatite. Choice D is incorrect as it refers to the epiphysis, which is not synonymous with hydroxyapatite.
