Practice TEAS Science Test Questions
Question 1 of 5
Which region of the small intestine is the primary site of absorption?
Correct Answer: B
Rationale: Failed to generate a rationale of 500+ characters after 5 retries.
Question 2 of 5
What is the function of the Vas Deferens?
Correct Answer: D
Rationale: The vas deferens is a duct that connects each testis to the urethra, allowing the transport of sperm. Choice A is incorrect because the vas deferens does not produce fluid to increase sperm mobility. Choice B is incorrect as the vas deferens is not a site for egg maturation. Choice C is incorrect as the vas deferens does not help control urine flow, its primary role is in the transport of sperm.
Question 3 of 5
Which of the following indicates the body's draining of clear fluid throughout the body to protect it from infection?
Correct Answer: C
Rationale: The correct answer is C, the Lymphatic System. The lymphatic system is responsible for draining clear fluid, known as lymph, throughout the body to protect it from infection. The other choices are incorrect because the pulmonary loop specifically refers to circulation between the heart and lungs, the systemic loop refers to circulation between the heart and the rest of the body, and the immune system is responsible for fighting infections and diseases rather than draining clear fluid.
Question 4 of 5
Which of the following is an end product of cellular respiration?
Correct Answer: B
Rationale: The correct answer is B: ATP energy. During cellular respiration, glucose is broken down to produce ATP, which is the primary energy currency of cells. While oxygen is required for cellular respiration to occur, it is not an end product but rather a reactant. Carbon dioxide and water are byproducts of cellular respiration, alongside ATP. Therefore, options A, C, and D are incorrect as they are not end products of cellular respiration.
Question 5 of 5
Which of the following is produced by Natural Killer Cells to create pores for target cell rupture?
Correct Answer: C
Rationale: The correct answer is C, Perforin. Natural Killer cells release perforin, which forms pores in the membrane of target cells, leading to their lysis. Interferon (choice A) is a protein released by cells in response to viral infections, apoptosis (choice B) is programmed cell death, and antibodies (choice D) are produced by B cells to neutralize pathogens but are not directly involved in creating pores for cell rupture like perforin.
