TEAS version 7 quizlet science
1. Which of the following is NOT a type of antibody?
- A. IgA
- B. IgM
- C. Interferon
- D. IgG
Correct answer: C
Rationale: A) IgA: This is a type of antibody found in mucosal areas such as the gut, respiratory tract, and genitourinary tract. It plays a role in mucosal immunity. B) IgM: This is a type of antibody produced during the primary immune response and is the first antibody to be produced in response to an infection. C) Interferon: Interferons are signaling proteins produced by cells in response to viral infections. They play a role in the immune response by interfering with viral replication, but they are not antibodies. D) IgG: This is the most abundant type of antibody in the bloodstream and is involved in long-term immunity. Therefore, the correct answer is C) Interferon, as it is not a type of antibody.
2. According to Newton's third law of motion, if you push against a wall with a certain force, the wall will push back with:
- A. A smaller force
- B. An equal force
- C. A greater force
- D. No force at all
Correct answer: B
Rationale: According to Newton's third law of motion, for every action, there is an equal and opposite reaction. When you push against a wall with a certain force, the wall will push back on you with an equal force in the opposite direction. Choice A is incorrect because the wall exerts an equal force back. Choice C is incorrect as it suggests a greater force, which goes against Newton's third law. Choice D is incorrect as the wall does exert a force back in response to your push.
3. Four different groups of the same species of peas are grown and exposed to differing levels of sunlight, water, and fertilizer as documented in the table below. The data in the water and fertilizer columns indicate how many times the peas are watered or fertilized per week, respectively. Group 2 is the only group that withered. What is a reasonable explanation for this occurrence? Group Sunlight Water Fertilizer 1 partial sun 4 mL/hr 1 2 full sun 7 mL/hr 1 3 no sun 14 mL/hr 2 4 partial sun 3 mL/hr 2
- A. Insects gnawed away at the stem of the plant.
- B. The roots rotted due to poor drainage.
- C. The soil type had nutritional deficiencies.
- D. This species of peas does not thrive in full sunlight.
Correct answer: D
Rationale: Group 2, the only group that withered, was exposed to full sun. This suggests that the species of peas being studied does not thrive in full sunlight, leading to its deterioration compared to the other groups with different light exposures. Choices A, B, and C are not the correct explanations for the withering of Group 2. There is no mention of insects in the stem, poor drainage, or soil nutritional deficiencies in the scenario provided. The key factor that sets Group 2 apart from the others is the full sunlight exposure, indicating that the species of peas is not suited for such conditions.
4. Which structure in the respiratory system serves as the 'windpipe' that conducts air from the larynx to the bronchi?
- A. Trachea
- B. Larynx
- C. Bronchi
- D. Alveoli
Correct answer: A
Rationale: The correct answer is the trachea. The trachea, commonly referred to as the 'windpipe,' is a vital structure in the respiratory system that connects the larynx to the bronchi. It is made up of cartilage rings that provide structural support, preventing collapse and ensuring the unobstructed flow of air into the lungs. The trachea plays a crucial role in facilitating the passage of air from the upper respiratory tract to the lower respiratory tract. The larynx is responsible for sound production and is located above the trachea. The bronchi are the two main branches that lead from the trachea into the lungs, further branching into smaller airways. Alveoli are the tiny air sacs where gas exchange occurs in the lungs, but they are not the structure that serves as the 'windpipe' for air passage in the respiratory system.
5. What property best describes the characteristic that nuclear forces are much stronger than electromagnetic forces at the nuclear level?
- A. Short-range interaction
- B. Long-range interaction
- C. Repulsive force
- D. Dependent on charge only
Correct answer: A
Rationale: The correct answer is A: Short-range interaction. Nuclear forces are much stronger than electromagnetic forces at the nuclear level because they are short-range interactions that act over distances on the order of the size of an atomic nucleus. This short-range nature of nuclear forces allows them to be much stronger than the long-range electromagnetic forces, which weaken with distance according to the inverse square law. Choice B, long-range interaction, is incorrect because nuclear forces are short-range. Choice C, repulsive force, is incorrect as nuclear forces include both attractive and repulsive components. Choice D, dependent on charge only, is incorrect because nuclear forces are not solely determined by charge but also involve other factors like spin and isospin.
