Practice TEAS Science Test Questions
Question 1 of 5
Which of the following brain structures is responsible for emotions, emotional behavior, and motivation?
Correct Answer: A
Rationale: The correct answer is A: Amygdala. The amygdala is responsible for processing emotions, emotional behavior, and motivation. It plays a crucial role in fear and pleasure responses. It also helps in memory consolidation of emotional events. The other choices, B: Cerebellum, C: Hypothalamus, and D: Pons, do not primarily govern emotions and motivation. The cerebellum is mainly involved in motor control, the hypothalamus regulates basic functions like hunger and thirst, and the pons controls sleep and arousal. Therefore, the amygdala is the correct answer for its specific role in emotions and motivation.
Question 2 of 5
What is the role of platelets in the blood?
Correct Answer: D
Rationale: Platelets play a crucial role in clotting blood. When a blood vessel is damaged, platelets rush to the site to form a plug, preventing excessive bleeding. This process, known as hemostasis, involves platelets adhering to the damaged vessel wall, releasing chemicals to attract more platelets, and forming a clot to stop bleeding. Platelets do not transport oxygen (choice A), fight infection (choice B), or produce antibodies (choice C). Thus, the correct answer is D - Clot blood.
Question 3 of 5
Which part of the brain is responsible for controlling involuntary functions like breathing and heart rate?
Correct Answer: B
Rationale: The correct answer is B: Medulla oblongata. This part of the brain is located in the brainstem and is responsible for regulating essential involuntary functions such as breathing, heart rate, and blood pressure. It contains vital centers that control these functions, making it the correct choice. Rationale: 1. Cerebrum (A): The cerebrum is responsible for higher brain functions such as thinking, memory, and voluntary movements. It does not directly control involuntary functions like breathing and heart rate. 2. Cerebellum (C): The cerebellum is involved in coordination, balance, and muscle movement but does not regulate involuntary functions like breathing and heart rate. 3. Thalamus (D): The thalamus acts as a relay center for sensory information but is not primarily involved in controlling involuntary functions like breathing and heart rate. In summary, the Medulla oblongata is the correct answer because it specifically houses the centers that control vital involuntary functions, distinguishing
Question 4 of 5
Which blood type is known as the universal donor?
Correct Answer: D
Rationale: The correct answer is D: Type O. Type O blood lacks both A and B antigens, making it compatible with all blood types. As a result, it can be safely transfused to individuals with any blood type, earning it the title of the universal donor. Choice A (Type A) has A antigens, Choice B (Type B) has B antigens, and Choice C (Type AB) has both A and B antigens, making them not suitable for universal donation.
Question 5 of 5
Which method is most suitable for measuring the volume of a cube?
Correct Answer: B
Rationale: The correct answer is B: Measuring wheel and mathematical formula. To measure the volume of a cube, you need to measure the length of one side using a measuring wheel and then use the formula V = s^3, where V is the volume and s is the length of one side. This method is suitable because it directly measures the side length of the cube, which is essential for calculating the volume accurately. Choice A, the triple beam balance, is used for measuring mass, not volume. Choice C, the graduated cylinder, is used to measure the volume of irregularly shaped objects using water displacement method, not ideal for a cube. Choice D, the measuring wheel alone, does not provide the formula for calculating the volume of a cube, making it less suitable compared to choice B.
