ATI TEAS Practice Test Science
1. An FBI agent has spent her career studying individual serial killers. From this data, she creates a theory about the traits of these killers. What type of reasoning has she 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 a general conclusion from specific observations or data, which fits the scenario described where the FBI agent has studied individual serial killers and formulated a theory about their traits based on this specific data. Deductive reasoning (choice A) starts with general information and applies it to a specific case, which is not the case here. Conductive reasoning (choice B) and quantitative reasoning (choice C) are not relevant to the scenario provided.
2. Which of the following is a unit of power?
- A. Newton-meter (N·m)
- B. Joule (J)
- C. Watt (W)
- D. Kilogram (kg)
Correct answer: C
Rationale: The correct answer is C: Watt (W). Power is the rate at which work is done or energy is transferred. The unit of power is the watt (W), named after James Watt, the inventor of the steam engine. A Newton-meter (N·m) is a unit of torque, Joule (J) is a unit of energy, and Kilogram (kg) is a unit of mass, not power. Therefore, choices A, B, and D are incorrect as they represent units of torque, energy, and mass, respectively, and not power.
3. Which element is present in household bleach and has disinfectant properties?
- A. Sodium
- B. Chlorine
- C. Fluorine
- D. Iodine
Correct answer: B
Rationale: The correct answer is B, Chlorine. Chlorine is the element present in household bleach that provides disinfectant properties due to its oxidizing ability. Chlorine is effective in killing bacteria and other microorganisms. Sodium (Choice A) is a component of common table salt and not the active disinfectant in bleach. Fluorine (Choice C) is not typically found in household bleach but is used in fluoride products. Iodine (Choice D) is used as a disinfectant in some contexts but is not the primary element in household bleach.
4. What is the function of the Golgi apparatus?
- A. Breaking down and recycling cellular waste
- B. Packaging and transporting proteins and lipids
- C. Generating energy through cellular respiration
- D. Translating DNA into proteins
Correct answer: B
Rationale: The Golgi apparatus plays a crucial role in the cell by packaging and modifying proteins and lipids synthesized by the endoplasmic reticulum. These proteins and lipids are then transported to their final destinations within the cell or outside of it. The Golgi apparatus does not break down and recycle cellular waste, generate energy through cellular respiration, or translate DNA into proteins. Its primary function is related to processing and sorting molecules for cellular use.
5. Which of the following terms describes the enlargement of an organ or tissue?
- A. Dystrophy
- B. Atrophy
- C. Hypertrophy
- D. Eutrophy
Correct answer: C
Rationale: Hypertrophy refers to the enlargement of an organ or tissue, typically due to an increase in the size of individual cells. This can occur in response to increased workload, hormonal stimulation, or other factors. On the other hand, dystrophy refers to the degeneration and deterioration of tissue, atrophy describes the decrease in the size of an organ or tissue, and eutrophy denotes a state of normal nutrition or growth. Therefore, the correct answer is 'Hypertrophy' as it specifically relates to the increase in size or volume of an organ or tissue.
