TEAS version 7 quizlet science
1. During micturition, the process involves a combination of:
- A. Gravity alone
- B. Voluntary muscle contractions only
- C. Involuntary muscle contractions only
- D. Both voluntary and involuntary muscle contractions
Correct answer: D
Rationale: During micturition, which is the process of urination, both voluntary and involuntary muscle contractions are involved. Voluntary muscle contractions include the relaxation of the external urethral sphincter, allowing the release of urine, while involuntary muscle contractions involve the detrusor muscle in the bladder contracting to expel urine. Choices A, B, and C are incorrect because micturition is not solely dependent on gravity, voluntary muscle contractions, or involuntary muscle contractions alone. The correct answer is D as both types of muscle contractions are necessary for the complete process of urination.
2. Which of the following factors does not strengthen a scientific argument?
- A. Lack of bias
- B. Extensive use of qualitative research and data
- C. Able to be reproduced and repeated by others
- D. Withstands the test of time
Correct answer: B
Rationale: The correct answer is B. While qualitative data can provide valuable insights, it does not inherently strengthen a scientific argument to the same extent as quantitative data. Quantitative data is generally more precise, measurable, and easier to verify, making it a stronger basis for scientific arguments. Choices A, C, and D all contribute to strengthening a scientific argument. Lack of bias ensures objectivity and reliability, reproducibility by others validates the findings, and standing the test of time indicates the enduring validity and reliability of the argument.
3. Which kingdom primarily consists of multicellular, photosynthetic organisms with cell walls made of cellulose?
- A. Animalia
- B. Fungi
- C. Plantae
- D. Protista
Correct answer: C
Rationale: A) Animalia consists of multicellular organisms that lack cell walls and are heterotrophic. Therefore, it does not primarily consist of photosynthetic organisms with cell walls made of cellulose. B) Fungi are multicellular organisms with cell walls made of chitin and are heterotrophic, so they do not fit the description. C) Plantae primarily consists of multicellular, photosynthetic organisms with cell walls made of cellulose. This accurately describes plants. D) Protista is a diverse kingdom that includes unicellular and multicellular organisms with varying characteristics, but it does not primarily consist of multicellular, photosynthetic organisms with cell walls made of cellulose.
4. What is the term for the maximum amount of solute that can dissolve in a solvent at a specific temperature and pressure?
- A. Molarity
- B. Solubility
- C. Concentration
- D. Saturation
Correct answer: B
Rationale: Solubility is the correct term for the maximum amount of solute that can dissolve in a solvent at a specific temperature and pressure. Molarity is a measure of concentration, not the maximum amount that can dissolve. Concentration is a general term for the amount of solute present in a given amount of solvent. Saturation is related to solubility but specifically refers to a state where no more solute can be dissolved in the solvent.
5. When sodium hydroxide (NaOH) reacts with hydrochloric acid (HCl), the resulting product is:
- A. Hydrogen gas and sodium chloride (NaCl)
- B. Chlorine gas and sodium oxide (Na2O)
- C. Sodium metal (Na) and water (H2O)
- D. No reaction occurs.
Correct answer: A
Rationale: When sodium hydroxide (NaOH) reacts with hydrochloric acid (HCl), a neutralization reaction occurs. The products of this reaction are water (H2O) and a salt, which is sodium chloride (NaCl). The chemical equation for this reaction is: NaOH + HCl -> NaCl + H2O. Choice B is incorrect because chlorine gas and sodium oxide are not the products of this reaction. Choice C is incorrect as sodium metal and water are not the products formed in this neutralization reaction. Choice D is incorrect because a reaction does occur between NaOH and HCl, resulting in the formation of NaCl and H2O. Therefore, the correct answer is A: Hydrogen gas and sodium chloride (NaCl).
