ATI TEAS Science Practice Test
1. What is the dermis composed of?
- A. Adipose tissue
- B. Epithelial cells
- C. Connective tissue
- D. Muscle tissue
Correct answer: C
Rationale: The correct answer is C: Connective tissue. The dermis is primarily composed of connective tissue, which includes collagen and elastin fibers that provide strength and elasticity to the skin. It houses blood vessels, nerve endings, hair follicles, and glands, playing a crucial role in supporting the skin structure and function. Adipose tissue (choice A) is found in the subcutaneous layer beneath the dermis, providing insulation and energy storage. Epithelial cells (choice B) form the outermost layer of the skin called the epidermis. Muscle tissue (choice D) is not a significant component of the dermis but is found deeper in the body associated with movement and support.
2. Which of the following organs is part of the central nervous system?
- A. Heart
- B. Brain
- C. Liver
- D. Lungs
Correct answer: B
Rationale: The correct answer is B: Brain. The brain is a vital organ that is part of the central nervous system, along with the spinal cord. It plays a crucial role in processing information, controlling body functions, and coordinating responses to stimuli. The heart, liver, and lungs are not part of the central nervous system; they belong to the cardiovascular and respiratory systems, respectively. The heart is part of the cardiovascular system, responsible for pumping blood throughout the body. The liver is part of the digestive system, involved in processes like detoxification and metabolism. The lungs are part of the respiratory system, facilitating the exchange of oxygen and carbon dioxide during breathing.
3. Which of the following would be a useful source of information to determine the validity of the argument presented in the passage?
- A. A survey of high school students' preferences regarding foreign language requirements.
- B. A comparison of the correlation between a second language introduced at home and subsequent college acceptance rates.
- C. A survey asking parents to select the foreign language they would like their children to study in high school.
- D. A comparison of the correlation between high school students' study of a foreign language and subsequent college acceptance rates.
Correct answer: D
Rationale: The passage emphasizes the importance of studying a foreign language in high school for future success, including college acceptance rates and job market demand. To evaluate the argument's validity, it is crucial to examine the direct impact of studying a foreign language on college acceptance rates. Choice D is the correct answer because it directly addresses this aspect by comparing the correlation between high school students' study of a foreign language and subsequent college acceptance rates. This comparison would provide concrete evidence supporting or refuting the argument presented in the passage. Choices A, B, and C, though related to language education, do not directly assess the specific relationship between studying a foreign language in high school and college acceptance rates, making them less relevant for evaluating the argument's validity.
4. The cost of renting a car is $50 per day plus $0.25 per mile driven. If a customer rents the car for 3 days and drives 120 miles, what is the total cost?
- A. $156
- B. $190
- C. $165
- D. $210
Correct answer: A
Rationale: To calculate the total cost, first, multiply the number of days by the cost per day: 3 days x $50/day = $150. Then, multiply the number of miles driven by the cost per mile: 120 miles x $0.25 = $30. Finally, add the two amounts together: $150 (daily cost) + $30 (mileage cost) = $180. Therefore, the correct total cost is $180, which corresponds to choice A. The other choices are incorrect because they do not reflect the accurate calculation of $150 for the daily cost and $30 for the mileage cost.
5. At the beginning of the day, Xavier has 20 apples. At lunch, he meets his sister Emma and gives her half of his apples. After lunch, he stops by his neighbor Jim's house and gives him 6 of his apples. He then uses ¾ of his remaining apples to make an apple pie for dessert at dinner. At the end of the day, how many apples does Xavier have left?
- A. 4
- B. 6
- C. 2
- D. 1
Correct answer: D
Rationale: Xavier starts with 20 apples. He gives half to Emma, leaving him with 10 apples. After giving 6 more to Jim, he has 4 apples left. Using ¾ of the remaining 4 apples for the pie leaves him with 1 apple at the end of the day. Choice A is incorrect because it doesn't account for the apple pie Xavier made. Choices B and C are incorrect as they don't reflect the correct calculations of apples remaining after each step.
