ATI TEAS 7
English TEAS Practice Test
1. Which of the following is correctly punctuated?
- A. The artist Prince, whose death shocked America in April of 2016, was one of the most successful musical artists of the last century.
- B. The artist Prince, whose death shocked America in April of 2016, was one of the most successful musical artists of the last century.
- C. The artist Prince—whose death shocked America in April of 2016—was one of the most successful musical artists of the last century.
- D. The artist Prince, whose death shocked America in April of 2016, was one of the most successful musical artists of the last century.
Correct answer: B
Rationale: The correct punctuation in this case is to use a comma (,) to set off the nonrestrictive clause 'whose death shocked America in April of 2016.' This clause provides additional information about the artist Prince without changing the essential meaning of the sentence. Choice A has a semicolon (;) which is incorrect as it separates two closely related independent clauses. Choice C uses em dashes (—) which are incorrect as they should be used for emphasis or to set off information. Choice D uses a colon (:) which is incorrect as it introduces a list or an explanation, not additional information about the artist Prince. Therefore, the correctly punctuated sentence is: 'The artist Prince, whose death shocked America in April of 2016, was one of the most successful musical artists of the last century.'
2. Which level of protein structure is defined by the folds and coils of the protein's polypeptide backbone?
- A. Primary
- B. Secondary
- C. Tertiary
- D. Quaternary
Correct answer: B
Rationale: The correct answer is B: Secondary. The secondary structure of a protein is defined by the folds and coils of the protein's polypeptide backbone. This level of structure is characterized by the formation of alpha helices and beta sheets, which are stabilized by hydrogen bonds between amino acids along the polypeptide chain. Choice A, Primary, refers to the linear sequence of amino acids in the protein. Choice C, Tertiary, involves the 3D folding of the entire polypeptide chain. Choice D, Quaternary, pertains to the arrangement of multiple polypeptide subunits in a protein complex.
3. A mathematics test has a 4:2 ratio of data analysis problems to algebra problems. If the test has 18 algebra problems, how many data analysis problems are on the test?
- A. 24
- B. 28
- C. 36
- D. 38
Correct answer: C
Rationale: The ratio of 4:2 simplifies to 2:1. This means that for every 2 algebra problems, there is 1 data analysis problem. If there are 18 algebra problems, we can set up a proportion: 2 algebra problems correspond to 1 data analysis problem. Therefore, 18 algebra problems correspond to x data analysis problems. Solving the proportion, x = 18 * 1 / 2 = 9. Hence, there are 9 data analysis problems on the test. Therefore, the total number of data analysis problems on the test is 18 (algebra problems) + 9 (data analysis problems) = 27.
4. During the process of oogenesis, primary oocytes produce:
- A. sperm.
- B. eggs.
- C. oogonia.
- D. stem cells.
Correct answer: B
Rationale: During the process of oogenesis, primary oocytes undergo meiosis to develop into secondary oocytes, which are the matured eggs released during ovulation for potential fertilization. Therefore, primary oocytes produce eggs, not sperm, oogonia, or stem cells, during oogenesis. Choice A (sperm) is incorrect as sperm is produced through spermatogenesis in males. Choice C (oogonia) is incorrect as oogonia are the cells that give rise to primary oocytes but are not the direct product of primary oocytes. Choice D (stem cells) is incorrect as primary oocytes do not directly produce stem cells during oogenesis.
5. Express 3 5/7 as an improper fraction.
- A. 26/7
- B. 21/7
- C. 22/7
- D. 26/5
Correct answer: A
Rationale: To convert a mixed number to an improper fraction, multiply the whole number by the denominator of the fraction, then add the numerator. In this case, 3 * 7 + 5 = 21 + 5 = 26. So, 3 5/7 as an improper fraction is 26/7. Choice B (21/7) is incorrect because it represents the original fraction 3 5/7. Choice C (22/7) is incorrect and represents a different fraction. Choice D (26/5) is incorrect and does not reflect the proper conversion of the mixed number to an improper fraction.
