TEAS version 7 quizlet science
1. Which hormone stimulates the release of pancreatic enzymes and bile?
- A. Gastrin
- B. Insulin
- C. Cholecystokinin (CCK)
- D. Glucagon
Correct answer: C
Rationale: Cholecystokinin (CCK) is the correct answer. It is the hormone that stimulates the release of pancreatic enzymes and bile. CCK is released by the small intestine in response to the presence of fats and proteins in the duodenum, triggering the release of digestive enzymes and bile to aid in the digestion of fats and proteins. Gastrin (Choice A) primarily stimulates gastric acid secretion, not the release of pancreatic enzymes and bile. Insulin (Choice B) regulates blood sugar levels by promoting glucose uptake. Glucagon (Choice D) raises blood glucose levels by stimulating the breakdown of glycogen in the liver.
2. What is the term for the process of a gas changing directly into a solid?
- A. Condensation
- B. Deposition
- C. Sublimation
- D. Evaporation
Correct answer: B
Rationale: The correct term for the process of a gas changing directly into a solid is deposition. During deposition, gas particles lose energy and transition directly into the solid state without passing through the liquid phase. Sublimation, on the other hand, is the process in which a solid changes directly into a gas without going through the liquid phase. Condensation is the process where gas changes into a liquid state. Evaporation, on the contrary, is the conversion of a liquid to a gas. Therefore, the correct answer is B, deposition.
3. Four different groups of the same species of peas are grown and exposed to differing levels of sunlight, water, and fertilizer as documented in the table below. The data in the water and fertilizer columns indicate how many times the peas are watered or fertilized per week, respectively. Group 2 is the only group that withered. What is a reasonable explanation for this occurrence? Group Sunlight Water Fertilizer 1 partial sun 4 mL/hr 1 2 full sun 7 mL/hr 1 3 no sun 14 mL/hr 2 4 partial sun 3 mL/hr 2
- A. Insects gnawed away at the stem of the plant.
- B. The roots rotted due to poor drainage.
- C. The soil type had nutritional deficiencies.
- D. This species of peas does not thrive in full sunlight.
Correct answer: D
Rationale: Group 2, the only group that withered, was exposed to full sun. This suggests that the species of peas being studied does not thrive in full sunlight, leading to its deterioration compared to the other groups with different light exposures. Choices A, B, and C are not the correct explanations for the withering of Group 2. There is no mention of insects in the stem, poor drainage, or soil nutritional deficiencies in the scenario provided. The key factor that sets Group 2 apart from the others is the full sunlight exposure, indicating that the species of peas is not suited for such conditions.
4. A researcher wants to investigate the relationship between family income and quality of medical care. Which statement provides the best reason to conduct this investigation?
- A. The researcher can identify affordable medical care to recommend to low-income families.
- B. The investigation can help identify individuals who are healthy so they can maintain their health.
- C. Results of this investigation may identify a group of people who do not receive quality medical care and could benefit from improved medical treatments.
- D. There is a valid reason to conduct this investigation.
Correct answer: C
Rationale: The correct answer is C because identifying a group of individuals who do not receive quality medical care can lead to targeted interventions to improve their access to better medical treatments. This investigation can help address disparities in healthcare and improve outcomes for those in need. Choice A is incorrect because the focus is on identifying those who lack quality medical care, not just affordable care. Choice B is incorrect as it misinterprets the purpose of the investigation, which is to improve medical care for those not receiving quality care, rather than maintaining the health of those already healthy. Choice D is too vague and does not provide a specific reason for conducting the investigation, unlike choice C which highlights the potential benefits of identifying individuals in need of improved medical treatments.
5. A person pushes a box across a floor with a constant force. The box eventually comes to a stop due to friction. What happens to the work done by the person?
- A. It increases as the box moves further.
- B. It decreases as the box slows down.
- C. It remains constant throughout the motion.
- D. It becomes zero once the box stops.
Correct answer: D
Rationale: Work done is defined as the product of the force applied and the distance moved in the direction of the force. In this scenario, when the box comes to a stop, the displacement becomes zero, leading to zero work done by the person. Choice A is incorrect as the work done is not increasing, but rather decreasing as the box slows down. Choice B is incorrect because the work done does not decrease as the box slows down; it becomes zero when the box stops. Choice C is incorrect as the work done is not constant but decreases to zero when the box stops.
