TEAS Test 7 science quizlet

1. What is the term for the tiny particles that make up atoms?

Correct answer: D

Rationale: The correct answer is 'Subatomic particles.' Subatomic particles are the tiny components that constitute atoms, including protons, neutrons, and electrons. Protons and neutrons are located in the nucleus of an atom, while electrons revolve around the nucleus. Choices A, B, and C specifically refer to individual subatomic particles but do not encompass the complete range of particles within an atom.

2. What is the term for the first exposure to a specific pathogen, leading to the development of an initial immune response?

Correct answer: A

Rationale: The correct answer is A: Primary immune response. The primary immune response refers to the initial encounter with a specific pathogen, which triggers the development of the first immune response by the immune system. This response involves activating immune cells like B cells and T cells to produce antibodies and memory cells specific to that pathogen. On the other hand, the secondary immune response occurs upon re-exposure to the same pathogen and is characterized by a faster, stronger, and more effective immune response due to the presence of memory cells from the primary response. Choices B, C, and D are incorrect. The secondary immune response is the response upon re-exposure, hypersensitivity reactions are exaggerated immune responses to antigens, and immunological tolerance is the immune system's ability to recognize and tolerate self-antigens without mounting an immune response.

3. Which of the following words, as used in the timeline, indicates the chronology of events in Barton's life?

Correct answer: C

Rationale: 'After' is used to indicate that one event happened following another in time. In the context of a timeline, 'After' signifies the sequence of events, showing what occurred subsequent to a particular point in time. In the provided extract, events unfold in a specific order, with each event happening 'after' the previous one. Choices A, B, and D do not inherently convey the idea of chronological order and are not suitable for indicating the sequence of events in a timeline.

4. Which three parts make up the large intestine?

Correct answer: B

Rationale: The correct answer is B: Cecum, colon, rectum. The large intestine is composed of the cecum, colon, and rectum. These parts are responsible for water absorption and feces formation. Choices A, C, and D are incorrect. A contains parts of the small intestine (duodenum, ileum, jejunum), C has a mix of small and large intestine parts, and D includes the small intestine part ileum. Understanding the correct anatomy of the large intestine is essential for distinguishing it from the small intestine.

5. What is the term for the ability of a substance to dissolve in another substance?

Correct answer: A

Rationale: Solubility is the property that describes the ability of a substance to dissolve in another substance. When a substance is soluble in another, it means it can form a homogeneous solution by dispersing at a molecular level within the solvent. Miscibility, on the other hand, refers to the ability of two liquids to mix and form a homogeneous solution. Immiscibility indicates the inability of substances to mix to form a homogeneous solution. Reactivity pertains to the ability of a substance to undergo chemical reactions, which is distinct from the concept of solubility.
