ATI TEAS 7 Science Practice Test

1. Which of the following is NOT part of the circulatory system?

Correct answer: A

Rationale: The correct answer is A: Kidneys. The kidneys are part of the urinary system, responsible for filtering waste and maintaining fluid balance in the body. In the circulatory system, the heart pumps blood, blood carries oxygen and nutrients, and blood vessels transport blood throughout the body. Choices B, C, and D are all components of the circulatory system, making the kidneys the correct choice as it belongs to the urinary system.

2. Which of the following terms describes the enlargement of an organ or tissue?

Correct answer: C

Rationale: Hypertrophy refers to the enlargement of an organ or tissue, typically due to an increase in the size of individual cells. This can occur in response to increased workload, hormonal stimulation, or other factors. On the other hand, dystrophy refers to the degeneration and deterioration of tissue, atrophy describes the decrease in the size of an organ or tissue, and eutrophy denotes a state of normal nutrition or growth. Therefore, the correct answer is 'Hypertrophy' as it specifically relates to the increase in size or volume of an organ or tissue.

3. What is the primary function of the strong nuclear force?

Correct answer: B

Rationale: The strong nuclear force primarily functions to bind protons and neutrons within the nucleus. It is responsible for overcoming the electrostatic repulsion between positively charged protons, holding the nucleus together. Choices A, C, and D are incorrect because the strong nuclear force specifically acts on nucleons (protons and neutrons) within the nucleus, not on electrons in atomic orbitals or charges outside the nucleus.

4. Given the style of writing for the passage, which of the following magazines would be the best fit for this article?

Correct answer: B

Rationale: The article's style is light-hearted and aimed at families looking for outdoor adventures. It suggests activities suitable for families with children, making Family Fun Days the best fit among the given magazine options. 'Scientific Spelunking' may focus more on the scientific aspects rather than family-friendly fun. 'Adventures for Men' may cater to a male audience rather than families. 'Mud Magazine' seems more focused on mud-related content, which doesn't align with the family-friendly, outdoor adventure theme of the article.

5. What is the small repeating unit in the contractile apparatus of skeletal muscle?

Correct answer: C

Rationale: The correct answer is 'Sarcomere.' The sarcomere is the smallest repeating unit within myofibrils and is responsible for muscle contraction in skeletal muscle. It consists of overlapping actin and myosin filaments arranged in a highly organized structure that allows for the sliding of filaments during muscle contraction. 'Myofibril' (choice A) is incorrect because it is a larger structure composed of sarcomeres. 'Actin' (choice B) and 'Myosin' (choice D) are incorrect as they are individual proteins that are components of the sarcomere, not the smallest repeating unit itself.
