TEAS Test 7 science quizlet
1. Which organelle is responsible for cellular respiration, producing ATP for energy?
- A. Nucleus
- B. Mitochondria
- C. Golgi apparatus
- D. Vacuole
Correct answer: B
Rationale: The correct answer is B) Mitochondria. Mitochondria are known as the powerhouse of the cell because they are responsible for cellular respiration, a process that produces ATP (adenosine triphosphate) for energy. The other organelles listed, such as the nucleus, Golgi apparatus, and vacuole, have distinct functions within the cell and are not directly involved in cellular respiration. The nucleus contains genetic material, the Golgi apparatus is involved in protein processing and packaging, and the vacuole is responsible for storage and maintaining cell turgor pressure.
2. Which of the following statements is true about Noble gases?
- A. They are non-reactive.
- B. They are highly reactive.
- C. They have 8 valence electrons.
- D. They have 7 valence electrons.
Correct answer: A
Rationale: The correct answer is A: Noble gases are non-reactive because they have a full valence shell with 8 electrons, making them stable and unlikely to form chemical bonds with other elements. Choice B is incorrect because Noble gases are known for their inertness and lack of reactivity. Choice C is incorrect because Noble gases have 8 valence electrons, which is a key characteristic that contributes to their stability. Choice D is incorrect because Noble gases have 8 valence electrons, not 7.
3. 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.
4. In the context of the cardiac cycle, what does the P wave on an electrocardiogram (ECG) represent?
- A. Atrial depolarization
- B. Ventricular depolarization
- C. Atrial repolarization
- D. Ventricular repolarization
Correct answer: A
Rationale: The P wave on an electrocardiogram (ECG) represents atrial depolarization, which signifies the electrical activation of the atria as they prepare to contract. During the cardiac cycle, atrial depolarization occurs first, leading to atrial contraction. Ventricular depolarization is represented by the QRS complex, not the P wave. Choices B, C, and D are incorrect because the P wave specifically corresponds to atrial depolarization, not ventricular depolarization, atrial repolarization, or ventricular repolarization.
5. Which of the following is a major factor influencing the distribution of organisms geographically?
- A. The availability of specific types of food sources
- B. Tolerance of organisms to different temperature ranges
- C. Competition for mates within the same species
- D. All of the above
Correct answer: D
Rationale: The distribution of organisms geographically is influenced by various factors. The availability of specific types of food sources is crucial as organisms need suitable food sources to survive and thrive in an area. Tolerance of organisms to different temperature ranges is also important, as temperature impacts where species can live. Organisms must withstand temperature conditions to survive. Competition for mates within the same species affects population sizes and dynamics in different areas. Therefore, all these factors collectively influence the distribution of organisms geographically. Choice D, 'All of the above,' is the correct answer because each of the factors mentioned (availability of food sources, tolerance to temperature ranges, and competition for mates) plays a significant role in determining the distribution of organisms in different geographical locations. Choices A, B, and C are incorrect because they each only represent one specific factor that influences distribution, whereas the correct answer encompasses all the major factors mentioned.
