ATI TEAS 7
Reading
1. The author expresses concern about the...
- A. high cost and limited efficiency of traditional fossil fuel power plants.
- B. unpredictable weather patterns and their impact on renewable energy production.
- C. increasing dependence on technology and potential cybersecurity risks.
- D. negative environmental consequences of renewable energy infrastructure.
Correct answer: B
Rationale: The passage's focus on managing the intermittency of renewable energy due to weather conditions implies concern about B.
2. Colligative properties of solutions depend on the...
- A. Concentration of the solvent
- B. All of the 3 answers given
- C. Chemical identity of the solute
- D. Number of solute particles in solution
Correct answer: D
Rationale: The correct answer is D: 'Number of solute particles in solution.' Colligative properties, such as boiling point elevation and freezing point depression, depend on the number of solute particles present in a solution, not on the chemical identity of the solute or the concentration of the solvent. This is because the presence of solute particles disrupts the solvent's normal behavior, affecting these properties. Therefore, the number of solute particles in solution directly influences colligative properties, making it the most accurate choice among the options provided.
3. Which sentence uses the pronoun "they" correctly?
- A. Her friends told her they liked her new haircut.
- B. Sarah and I, they went to the movies.
- C. They gave the awards to whomever deserved them.
- D. The birds, they were singing in the trees.
Correct answer: A
Rationale: Option A agrees with the closest noun, "friends."
4. ch 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: Elements within the same group share similar electron configurations in their outermost shells, resulting in comparable chemical properties. Helium and Neon both belong to Group 18 (Noble Gases), explaining their similarities.
5. The process of splitting a heavy nucleus into smaller nuclei, releasing a vast amount of energy, is called:
- A. Nuclear fusion
- B. Nuclear fission
- C. Radioactive decay
- D. Chain reaction
Correct answer: B
Rationale: Rationale: Nuclear fission is the process of splitting a heavy nucleus into smaller nuclei, releasing a vast amount of energy. This process is commonly used in nuclear power plants and nuclear weapons. A) Nuclear fusion is the process of combining two light nuclei to form a heavier nucleus, releasing energy in the process. This process powers the sun and other stars. C) Radioactive decay is the process by which an unstable atomic nucleus loses energy by emitting radiation. D) Chain reaction is a self-sustaining reaction in which the products of one reaction event stimulate further reaction events. This can occur in both nuclear fission and nuclear fusion reactions.
6. What is the main function of vacuoles in plant cells?
- A. To provide structural support for the cell
- B. To transport substances in and out of the cell
- C. To synthesize proteins and lipids
- D. To store water, enzymes, and waste products
Correct answer: D
Rationale: Rationale: Vacuoles in plant cells primarily function as storage organelles. They store water, enzymes, pigments, and waste products. Vacuoles help maintain turgor pressure within the cell, which provides structural support for the plant cell. While vacuoles can also be involved in transporting substances within the cell, their main function is storage. Synthesizing proteins and lipids is primarily carried out by other organelles such as the endoplasmic reticulum and Golgi apparatus.
