TEAS 7 science practice questions
1. Which of the following is NOT a risk factor for developing atherosclerosis?
- A. High blood pressure
- B. High levels of LDL cholesterol
- C. Regular physical activity
- D. Smoking
Correct answer: C
Rationale: Regular physical activity is not a risk factor for developing atherosclerosis; in fact, it is associated with a reduced risk. High blood pressure, high levels of LDL cholesterol, and smoking are all known risk factors for atherosclerosis. Regular physical activity plays a crucial role in improving cardiovascular health, reducing the risk of atherosclerosis, and maintaining overall well-being. Therefore, the correct answer is regular physical activity (choice C).
2. Which of the following functions corresponds to the parasympathetic nervous system?
- A. It stimulates the fight-or-flight response.
- B. It increases heart rate.
- C. It stimulates digestion.
- D. It increases bronchiole dilation.
Correct answer: C
Rationale: The parasympathetic nervous system is often referred to as the 'rest and digest' system because it promotes activities that occur when the body is at rest, such as digestion. This system helps stimulate digestion by increasing gastrointestinal motility, secretion of digestive enzymes, and blood flow to the digestive organs. Choices A, B, and D are incorrect because they are functions associated with the sympathetic nervous system, which is responsible for the 'fight-or-flight' response, increasing heart rate, and dilating bronchioles to facilitate more oxygen intake during stressful situations.
3. What is the primary function of the liver related to digestion?
- A. Produces bile
- B. Stores bile
- C. Converts waste ammonia into urea
- D. Filters and detoxifies digestion byproducts
Correct answer: D
Rationale: The primary function of the liver related to digestion is to filter and detoxify byproducts of digestion, including toxins and metabolic waste products. While the liver does produce bile and convert waste ammonia into urea, these functions are not directly related to digestion. Storing bile is mainly done by the gallbladder, not the liver.
4. A physician prescribes a drug to help control a person's anxiety attacks. This drug most likely targets the
- A. Amygdala.
- B. Parietal lobe.
- C. Hypothalamus.
- D. Sensory neuron.
Correct answer: A
Rationale: The correct answer is A: Amygdala. The amygdala is a key brain structure involved in the processing of emotions, including anxiety. Medications for anxiety disorders often target the amygdala to help regulate emotional responses and control anxiety attacks. The amygdala plays a crucial role in the brain's fear circuit and is essential for the appropriate response to stress and threat perception. Choices B, C, and D are incorrect because the parietal lobe is primarily involved in sensory processing and spatial reasoning, the hypothalamus regulates basic functions like hunger, thirst, and body temperature, and sensory neurons transmit signals from sensory receptors to the central nervous system, none of which are directly related to the regulation of anxiety attacks.
5. What is the main argument of this essay?
- A. iPads and Kindles are easier to read than books
- B. The printing press was a great invention
- C. The Internet is how people receive information
- D. Technology will soon replace printed material
Correct answer: D
Rationale: The main argument of the essay is that technology will soon replace printed material, specifically printed books. The passage discusses how the rise of the Internet and electronic devices like the iPad and Kindle are making printed books unnecessary. It presents a progression from oral tradition to printed books and now to digital and electronic options. The essay highlights how the convenience and multi-functionality of devices like the iPad and Kindle will lead to the eventual demise of printed books. Choices A, B, and C are incorrect because while they are mentioned in the essay, they are not the central argument. The essay focuses on the transition from printed material to digital and electronic options, making choice D the correct answer.
