TEAS Test 7 science
1. Which element shares the same group (family) on the periodic table with helium (He)?
- A. Neon (Ne)
- B. Boron (B)
- C. Carbon (C)
- D. Oxygen (O)
Correct answer: A
Rationale: Neon (Ne) shares the same group (family) on the periodic table with helium (He). Both helium and neon belong to Group 18 (Noble Gases) due to their complete and stable outer electron shells, making them chemically inert. Boron (B), Carbon (C), and Oxygen (O) are not in the same group as helium. Boron is in Group 13, Carbon is in Group 14, and Oxygen is in Group 16 on the periodic table.
2. Which structure, located between the pons and the spinal cord, plays a crucial role in coordinating movements, maintaining balance, and posture?
- A. Thalamus
- B. Medulla oblongata
- C. Cerebellum
- D. Hypothalamus
Correct answer: C
Rationale: The correct answer is the cerebellum. The cerebellum, located between the pons and the spinal cord, is responsible for coordinating movements, maintaining balance, and posture. The thalamus functions in relaying sensory and motor signals to the cerebral cortex, the medulla oblongata controls vital autonomic functions such as breathing and heart rate, and the hypothalamus regulates various bodily functions like temperature and hunger. Therefore, the cerebellum is the structure that specifically handles coordination, balance, and posture.
3. Which of the following contains only key points of the passage?
- A. Dr. Creekstone's 90th birthday party with 3000 guests, zebras, monster trucks, bagpipe player, limited buffet, and fireworks display.
- B. There were shocking buffet items at Dr. Creekstone's birthday party.
- C. Dr. Creekstone plans to have an even bigger and more interesting birthday party next year.
- D. Dr. Creekstone's 90th birthday party had 3000 guests, zebras, monster trucks, bagpipe player, limited buffet, and fireworks display.
Correct answer: A
Rationale: Choice A provides a comprehensive list of key points from the passage about Dr. Creekstone's 90th birthday party, including the number of guests, unique elements like zebras and monster trucks, the buffet contents, and the fireworks display. Choices B and C do not cover all the important details mentioned in the passage, making them incomplete and inaccurate. Choice D is a partial summary, missing essential details such as the unique elements and the limited buffet, so it is not the best option.
4. Which of the following sentences contains a homophone error?
- A. Their decision to stay home was vindicated when they heard about what happened.
- B. Jane was given a prescription for oral paste to put on her mouth ulcers.
- C. The team from Cincinnati led the league in scoring last year.
- D. What effect will this new legislation have on hospital policy?
Correct answer: B
Rationale: The correct answer is B because 'aural' and 'oral' are homophones, but they have different meanings. 'Aural' refers to hearing, while 'oral' refers to the mouth or spoken words. In the context of treating mouth ulcers, the correct term should be 'oral paste.' Choices A, C, and D do not contain homophone errors. In choice A, 'heard' is correctly used in the context of listening. Choice C is grammatically correct and does not involve homophones. Choice D correctly uses 'effect' and does not involve homophones.
5. Which of the following is NOT a tissue layer found in skeletal bone?
- A. periosteum
- B. bone marrow
- C. enamel
- D. cancellous bone
Correct answer: C
Rationale: Enamel is a hard, outer layer that covers the crown of a tooth and is not a tissue layer found in skeletal bone. The other options, periosteum, bone marrow, and cancellous bone, are all tissue layers or components found in skeletal bone. Periosteum is the connective tissue layer covering the bone surface, bone marrow is found within the bone cavities, and cancellous bone is a spongy, porous bone tissue.
