English and Language Usage TEAS
1. Usually I take a walk every day after breakfast, ____________ it was raining today.
- A. While
- B. Because
- C. But
- D. When
Correct answer: C
Rationale: The correct answer is 'But.' In this sentence, the conjunction 'but' is used to show a contrast between the usual routine of taking a walk after breakfast and the fact that it was raining today. 'While' suggests a concurrent action, 'Because' implies causation, and 'When' introduces a time relationship, none of which are suitable in this context.
2. What is the final phase of mitosis?
- A. Prophase
- B. Telophase
- C. Anaphase
- D. Metaphase
Correct answer: B
Rationale: Telophase is indeed the final phase of mitosis. During telophase, the chromosomes have reached opposite poles of the cell, the nuclear envelope is re-forming around the separated sister chromatids, and cytokinesis may also occur, leading to the division of the cell into two daughter cells. Choice A, Prophase, is incorrect as it is the initial phase of mitosis where chromatin condenses into chromosomes. Choice C, Anaphase, is incorrect as it is the phase where sister chromatids separate and move towards opposite poles. Choice D, Metaphase, is incorrect as it is the phase where chromosomes align at the cell's equator before separating.
3. What is the main purpose of biological classification?
- A. To create a rigid and unchanging system for labeling organisms
- B. To understand the diversity and interconnectedness of life
- C. To simplify nature into neat and tidy categories
- D. To assign organisms to specific ecological niches
Correct answer: B
Rationale: Biological classification, also known as taxonomy, is the science of categorizing and organizing living organisms based on shared characteristics. The main purpose of biological classification is not to create a rigid and unchanging system (option A) or to simplify nature into neat and tidy categories (option C). Instead, it aims to help us understand the diversity of life on Earth and how different organisms are related to each other. By classifying organisms into groups based on their evolutionary relationships, we can gain insights into the interconnectedness of life and better appreciate the complexity and beauty of the natural world. Assigning organisms to specific ecological niches (option D) is more related to ecological studies rather than biological classification.
4. How many liters are in 750 milliliters?
- A. 7.5 liters
- B. 0.75 liters
- C. 0.0075 liters
- D. 0.075 liters
Correct answer: B
Rationale: To convert milliliters to liters, you need to divide by 1000 since there are 1000 milliliters in a liter. Therefore, 750 milliliters divided by 1000 equals 0.75 liters. Choice A (7.5 liters) is incorrect as it is off by a factor of 10. Choice C (0.0075 liters) is incorrect as it is off by a factor of 100. Choice D (0.075 liters) is incorrect as it is off by a factor of 10.
5. Which of the following is a function of the skeletal system?
- A. To produce red blood cells
- B. To provide structural support
- C. To transport nutrients
- D. To store fat
Correct answer: B
Rationale: The correct answer is B: To provide structural support. The skeletal system is primarily responsible for supporting the body's structure, protecting internal organs, facilitating movement, and storing minerals. While bones do play a role in producing red blood cells (hematopoiesis) in the bone marrow, the main function related to the question is providing structural support. Choices C and D are incorrect as the skeletal system is not involved in transporting nutrients or storing fat. The main functions of the skeletal system are related to support, protection, movement facilitation, mineral storage, and hematopoiesis.
