TEAS 7 science quizlet
1. Which vitamin is essential for proper absorption of calcium and plays a role in lung function?
- A. Vitamin A
- B. Vitamin B12
- C. Vitamin D
- D. Vitamin E
Correct answer: C
Rationale: The correct answer is Vitamin D. Vitamin D is crucial for the proper absorption of calcium in the intestines and is essential for maintaining lung function. It regulates calcium and phosphorus levels, crucial for healthy bones and teeth. Vitamin A is important for vision and immune function, not specifically for calcium absorption or lung function. Vitamin B12 is essential for nerve function and red blood cell production, not related to calcium absorption or lung function. Vitamin E is an antioxidant that helps protect cells from damage, but it is not directly involved in calcium absorption or lung function.
2. How does the developing fetus primarily eliminate metabolic wastes?
- A. The developing fetus does not produce metabolic wastes.
- B. Fetal waste is excreted as feces, which pass into the mother's anus.
- C. Fetal waste is passed down the umbilical cord to the mother's circulatory system.
- D. Fetal waste is passed down the umbilical cord and leaves the mother's body via the vagina.
Correct answer: C
Rationale: Metabolic wastes produced by the developing fetus are eliminated primarily by being passed down the umbilical cord to the mother's circulatory system. Once in the mother's blood, these wastes are then filtered and excreted by the mother's kidneys. Choice A is incorrect because the developing fetus does produce metabolic wastes. Choice B is incorrect as fetal waste does not pass into the mother's anus. Choice D is incorrect as fetal waste does not leave the mother's body via the vagina.
3. Which of the following is an example of a commensal relationship between a microorganism and a human?
- A. Salmonella causing food poisoning
- B. taphylococcus aureus causing skin infections
- C. coli living in the gut
- D. Rabies virus causing neurological disease
Correct answer: C
Rationale: A commensal relationship is a type of symbiotic relationship in which one organism benefits, while the other is neither harmed nor benefited. In this case, E. coli living in the gut is an example of a commensal relationship because it can benefit from the environment in the gut without causing harm to the human host. Option A, Salmonella causing food poisoning, is an example of a pathogenic relationship where the microorganism causes harm to the host. Option B, Staphylococcus aureus causing skin infections, is also an example of a pathogenic relationship where the microorganism causes harm to the host. Option D, Rabies virus causing neurological disease, is another example of a pathogenic relationship where the microorganism causes harm to the host.
4. Which type of reasoning has the FBI agent used?
- A. Deductive Reasoning
- B. Conductive Reasoning
- C. Quantitative Reasoning
- D. Inductive Reasoning
Correct answer: D
Rationale: The correct answer is D: Inductive Reasoning. Inductive reasoning involves drawing general conclusions from specific observations or instances. In this case, the FBI agent is creating a theory based on observations of specific cases rather than applying a general rule to a specific situation (which would be deductive reasoning). Conductive reasoning is not a recognized type of reasoning, and quantitative reasoning involves interpreting and analyzing quantitative information.
5. Which of the following is NOT a function of the lymphatic system?
- A. Removing substances from the blood.
- B. Releasing hormones.
- C. Combating disease.
- D. Maintaining tissue fluid balance.
Correct answer: B
Rationale: The correct answer is B. Releasing hormones is not a function of the lymphatic system. The lymphatic system plays crucial roles in removing substances from the blood, combating disease through the production of immune cells, and maintaining tissue fluid balance by circulating lymph. Releasing hormones is primarily the function of endocrine glands, not the lymphatic system.
