TEAS version 7 quizlet science
1. Which of the following is NOT a greenhouse gas?
- A. Carbon dioxide
- B. Water vapor
- C. Nitrogen
- D. Methane
Correct answer: C
Rationale: Rationale: A) Carbon dioxide: Carbon dioxide is a greenhouse gas that is naturally present in the Earth's atmosphere and is also released through human activities such as burning fossil fuels. B) Water vapor: Water vapor is a greenhouse gas that is naturally present in the atmosphere and plays a significant role in the Earth's climate system. C) Nitrogen: Nitrogen is not considered a greenhouse gas because it does not have the ability to absorb and emit infrared radiation in the same way that greenhouse gases like carbon dioxide and methane do. D) Methane: Methane is a potent greenhouse gas that is released through natural processes such as wetland decomposition and human activities such as livestock farming and fossil fuel extraction. Therefore, the correct answer is C) Nitrogen, as it is not a greenhouse gas.
2. Which of the following is an example of adaptive immunity?
- A. Inflammation
- B. Fever
- C. Antibodies
- D. Phagocytosis
Correct answer: C
Rationale: Antibodies are produced by the adaptive immune system in response to specific antigens. They play a crucial role in targeting and neutralizing pathogens, providing long-lasting immunity against future infections. In contrast, options A (inflammation), B (fever), and D (phagocytosis) are examples of innate immunity, the body's immediate, non-specific defense mechanisms. Inflammation is a response to tissue damage, fever is a systemic response to infection, and phagocytosis is a process where cells engulf and digest pathogens, all part of the innate immune response.
3. What is the primary function of the large intestine?
- A. Digesting and absorbing nutrients
- B. Storing and mixing food
- C. Breaking down carbohydrates
- D. Absorbing water and electrolytes
Correct answer: D
Rationale: The primary function of the large intestine is to absorb water and electrolytes from the indigestible food matter that passes through it. This absorption process aids in the formation of solid waste (feces) before it is excreted from the body. Choices A, B, and C are incorrect because the large intestine does not primarily digest and absorb nutrients, store and mix food, or break down carbohydrates. These functions are primarily carried out by the small intestine.
4. Which of the following types of muscles is found in the walls of hollow organs?
- A. Cardiac
- B. Smooth
- C. Skeletal
- D. Voluntary
Correct answer: B
Rationale: Smooth muscles are the correct answer as they are found in the walls of hollow organs such as the intestines and blood vessels. Cardiac muscles are specifically found in the heart and are responsible for its contractions. Skeletal muscles are attached to bones and control voluntary movements. Voluntary muscles are under conscious control, but this term is not a specific type of muscle like smooth, cardiac, or skeletal muscles.
5. Where does the electron transport chain occur in the cell?
- A. Cytosol
- B. Golgi apparatus
- C. Inner mitochondrial membrane
- D. Nucleus
Correct answer: C
Rationale: The electron transport chain occurs in the inner mitochondrial membrane. This process is crucial for the generation of ATP, the cell's energy currency. Choice A (Cytosol) is incorrect as the electron transport chain does not take place in the cytosol. Choice B (Golgi apparatus) is also incorrect as the Golgi apparatus is involved in modifying, sorting, and packaging of proteins. Choice D (Nucleus) is incorrect as the nucleus houses the cell's genetic material but is not the location of the electron transport chain.
