ATI TEAS 7
ATI TEAS English Practice Test
1. What is the main idea of the paragraph?
- A. Coal mining is a dangerous job.
- B. Coal mining is a dirty job.
- C. Coal mining takes place underground.
- D. Coal miners risk injury on a daily basis.
Correct answer: A
Rationale: The main idea of the paragraph is to highlight the dangers associated with coal mining. The sentence 'Coal miners risk injury and health issues on a daily basis' supports the concept that coal mining is a dangerous job. Choice B is incorrect as it focuses on cleanliness rather than safety. Choice C is incorrect as the location of coal mining is not the primary focus of the paragraph. Choice D is incorrect as it does not encompass the full extent of risks mentioned in the paragraph.
2. Which of the following Mendelian laws describes how pairs of alleles within genes separate and recombine independently from other genes?
- A. law of segregation
- B. law of dominance
- C. law of independent assortment
- D. law of predictive traits
Correct answer: C
Rationale: The law of independent assortment describes how alleles of different genes segregate independently during gamete formation. This means that different gene pairs are passed on to offspring separately from one another, allowing for various combinations of traits. Gregor Mendel discovered this law, along with the law of segregation and the law of dominance, through his experiments with pea plants. The law of segregation (choice A) refers to how alleles of a gene separate during gamete formation, while the law of dominance (choice B) states that one allele can mask the presence of another in a heterozygous individual. The 'law of predictive traits' (choice D) is not a recognized Mendelian law and does not accurately describe the principles of genetic inheritance.
3. What is the primary function of DNA polymerase?
- A. Packaging DNA
- B. Replicating DNA
- C. Transcribing DNA
- D. Translating mRNA
Correct answer: B
Rationale: The correct answer is B: Replicating DNA. DNA polymerase is an enzyme responsible for synthesizing new DNA strands during DNA replication. It adds nucleotides to the growing DNA strand based on the template provided by the existing DNA strand. This process ensures that genetic information is accurately copied and passed on to daughter cells during cell division. Option A, Packaging DNA, refers to the coiling and organization of DNA into chromatin, a process involving histones and other proteins. Option C, Transcribing DNA, involves the synthesis of RNA from a DNA template, a process carried out by RNA polymerase. Option D, Translating mRNA, refers to the process of protein synthesis where the information encoded in mRNA is used to assemble amino acids into a polypeptide chain.
4. What is the Aufbau principle?
- A. The principle that electrons fill orbitals in order of increasing energy.
- B. The principle that electrons cannot occupy the same orbital with the same spin.
- C. The principle that the maximum number of electrons in an orbital is 2n^2, where n is the energy level of the orbital.
- D. The principle that the attractive force between an electron and the nucleus is inversely proportional to the distance between them.
Correct answer: A
Rationale: The Aufbau principle states that electrons fill orbitals in order of increasing energy. This principle helps to explain the electron configuration of atoms and how electrons are distributed within the energy levels and sublevels of an atom. By following the Aufbau principle, one can determine the electron configuration of an atom by sequentially adding electrons to orbitals in order of their increasing energy levels, starting with the lowest energy level. Choice B is incorrect as it describes the Pauli Exclusion Principle, which states that no two electrons in an atom can have the same four quantum numbers. Choice C is incorrect as it refers to the formula for calculating the maximum number of electrons that can occupy an energy level. Choice D is incorrect as it relates to Coulomb's law, which describes the electrostatic interaction between charged particles.
5. It can be inferred from the advertisement that
- A. A person staffing this position may work independently and/or as part of a team.
- B. Veronica Davis will make the hiring decisions.
- C. Caseloads will start out small for new hires.
- D. A candidate could work part-time if he or she chooses to.
Correct answer: A
Rationale: It can be inferred from the advertisement that a person staffing this position may work independently and/or as part of a team. The job description mentions the requirement for the ability to work both self-directed and as part of a team, indicating flexibility in working styles. Choice B is incorrect as Veronica Smith is mentioned as the contact for application submission, not the hiring decision-maker. Choice C is incorrect as there is no mention of caseload sizes for new hires. Choice D is incorrect as the advertisement does not specify part-time work as an option.
