TEAS Test 7 science quizlet
1. Which of the following is a common property of bases?
- A. Conductivity in aqueous solutions
- B. Sour taste
- C. Reactivity with metals to produce hydrogen gas
- D. Turns red litmus paper blue
Correct answer: D
Rationale: Bases are substances that can accept protons or donate hydroxide ions in a chemical reaction. One common property of bases is that they turn red litmus paper blue. This is a classic test to distinguish between acids (which turn blue litmus paper red) and bases. Conductivity in aqueous solutions (Option A) is a property of both acids and bases, but not unique to bases alone. Sour taste (Option B) is a property commonly associated with acids, not bases. Reactivity with metals to produce hydrogen gas (Option C) is a property of acids, particularly strong acids, but not bases.
2. Which type of tissue protects the respiratory system's trachea?
- A. Bone
- B. Cartilage
- C. Collagen
- D. Keratin
Correct answer: B
Rationale: Cartilage is the correct answer as it provides flexible support and protection in the trachea. Cartilage is specifically designed to maintain the trachea's shape and prevent it from collapsing during breathing. Bone is a rigid tissue, not found in the trachea, and would not provide the necessary flexibility for breathing. Collagen is a structural protein but does not offer the same support and flexibility as cartilage in this context. Keratin is a protein that forms structures like hair and nails, and it is not present in the trachea to provide protection.
3. Where does glycolysis occur within the cell?
- A. Cytosol
- B. Nucleus
- C. Mitochondria
- D. Endoplasmic reticulum
Correct answer: A
Rationale: Glycolysis occurs in the cytosol, the liquid component of the cytoplasm, not in the nucleus, mitochondria, or endoplasmic reticulum. It is the initial step in cellular respiration and involves the breakdown of glucose into pyruvic acid. The process takes place in the cytosol as it does not require membrane-bound organelles like the mitochondria or endoplasmic reticulum for its completion.
4. The spleen, a large lymphatic organ, is located in the:
- A. Chest
- B. Abdomen
- C. Pelvis
- D. Head and neck
Correct answer: B
Rationale: The spleen is located in the abdomen, specifically in the upper left part of the abdomen, under the ribcage and above the stomach. It is an important organ in the lymphatic system responsible for filtering blood, storing blood cells, and fighting infection. It is not located in the chest, pelvis, or head and neck regions. Therefore, the correct answer is 'B: Abdomen.' Choices 'A: Chest,' 'C: Pelvis,' and 'D: Head and neck' are incorrect as the spleen is not situated in these anatomical areas.
5. What is the study of fungi known as?
- A. Virology
- B. Mycology
- C. Bacteriology
- D. Parasitology
Correct answer: B
Rationale: Mycology is the correct answer. Mycology is the branch of biology that specifically deals with the study of fungi. Fungi constitute a separate kingdom of organisms that include various forms such as yeasts, molds, and mushrooms. Virology (A) is the study of viruses, while Bacteriology (C) focuses on bacteria. Parasitology (D) is the study of parasites, which may include protozoa, helminths, and some fungi, but it is not solely dedicated to fungi.
