ATI TEAS 7
Science TEAS Practice Test
1. Which of the following statements is FALSE regarding the use of qualitative and quantitative data in scientific research?
- A. Quantitative data is collected through numerical measurements.
- B. Quantitative data is more accurate than qualitative data.
- C. Qualitative data is focused on perspectives and behavior.
- D. Qualitative data is collected through observation and interviews.
Correct answer: B
Rationale: The correct answer is B because quantitative data is not inherently more accurate than qualitative data. Both types of data have their strengths and limitations, and the choice of data type depends on the research question and methodology. Quantitative data is collected through numerical measurements and involves statistical analysis. On the other hand, qualitative data focuses on perspectives, behaviors, and meanings and is typically gathered through observation and interviews. While quantitative data provides numerical precision, qualitative data offers in-depth insights into behaviors and perspectives that cannot be quantified, making them equally valuable in scientific research.
2. What is the law of conservation of energy?
- A. Energy cannot be created, only destroyed
- B. Energy can be created but not destroyed
- C. Energy can neither be created nor destroyed, only transformed from one form to another
- D. Energy is always created in any process
Correct answer: C
Rationale: The correct answer is C: 'Energy can neither be created nor destroyed, only transformed from one form to another.' The law of conservation of energy is a fundamental principle in physics. It states that the total energy in a closed system remains constant over time. Energy can change from one form to another (e.g., potential energy to kinetic energy), but the total amount of energy remains the same. Choices A, B, and D are incorrect because they do not accurately represent the law of conservation of energy. Energy is not created or destroyed according to this law, but rather transformed.
3. Which of the following is NOT a component of the genitourinary system?
- A. The kidneys
- B. The urethra
- C. The rectum
- D. The bladder
Correct answer: C
Rationale: The rectum is part of the digestive system, not the genitourinary system. The genitourinary system comprises organs involved in reproduction and urine formation and excretion, such as the kidneys, urethra, and bladder. Choices A, B, and D are all components of the genitourinary system. The kidneys filter blood and produce urine, the urethra is a tube that carries urine from the bladder out of the body, and the bladder stores urine before it is excreted.
4. What is the relationship between work and kinetic energy?
- A. Work is the cause of kinetic energy
- B. Kinetic energy is the result of work
- C. Work and kinetic energy are equivalent
- D. Work and kinetic energy are independent
Correct answer: A
Rationale: Work is defined as the transfer of energy that results in an object's displacement. When work is done on an object, it gains kinetic energy. This means that work is the cause of kinetic energy, as the energy transferred through work leads to the object's motion, which is represented by kinetic energy. Therefore, choice A is correct. Choice B is incorrect because kinetic energy is the result of work, not the other way around. Choice C is incorrect as work and kinetic energy are not equivalent but rather interconnected. Choice D is incorrect as work and kinetic energy are not independent; work leads to changes in kinetic energy.
5. What determines the defining characteristic of an element?
- A. Neutrons in its nucleus
- B. Electrons surrounding the nucleus
- C. Protons in its nucleus
- D. All of the above
Correct answer: C
Rationale: The defining characteristic of an element is determined by the number of protons in its nucleus, which is referred to as the atomic number. The number of protons uniquely identifies an element. The correct answer is choice C because the number of protons in the nucleus of an atom defines its elemental identity, as different elements have a unique number of protons. Neutrons and electrons do play essential roles in the atom, but they do not determine the defining characteristic of an element. Neutrons contribute to the stability of the nucleus and isotopes of an element, while electrons are involved in chemical bonding and the reactivity of an atom.
