TEAS version 7 quizlet science

1. Which of the following is NOT a function of the integumentary system?

Correct answer: D

Rationale: The correct answer is D. The production of digestive enzymes is not a function of the integumentary system. The integumentary system is responsible for regulating body temperature, protecting the body from pathogens, and synthesizing vitamin D. Digestive enzymes are produced by organs in the digestive system, such as the pancreas and stomach, and not by the integumentary system.

2. Which type of joint allows for the greatest range of motion?

Correct answer: B

Rationale: The correct answer is B: Ball-and-socket joint. The ball-and-socket joint, like the shoulder joint, allows for the greatest range of motion due to its structure, enabling movement in multiple directions. In contrast, hinge joints, pivot joints, and saddle joints have more restricted ranges of motion compared to ball-and-socket joints. Hinge joints primarily allow movement in one plane, pivot joints allow rotation around a central axis, and saddle joints have limited movement compared to ball-and-socket joints.

3. Which statement below best describes the process of condensation?

Correct answer: A

Rationale: The correct answer is A: 'Condensation is the process of changing from a gas to a liquid.' Condensation occurs when a gas cools and transforms into a liquid state. For example, when water vapor in the air cools and forms droplets, it is an example of condensation. This process is commonly observed in the formation of clouds or dew on grass in the early morning. Choice B is incorrect because it describes the process of vaporization rather than condensation. Choice C is incorrect as it refers to the process of melting. Choice D is incorrect as it describes sublimation, which is the transition from a solid to a gas without passing through the liquid phase.

4. A botanist wants to determine if environmental temperature affects root growth. What is the independent variable in this study?

Correct answer: A

Rationale: The correct answer is 'Temperature.' In an experiment, the independent variable is the factor that is deliberately manipulated or changed by the researcher. In this study, the botanist is specifically investigating how environmental temperature affects root growth, making temperature the independent variable. Choice B, 'Seedlings,' and Choice C, 'Light,' are not the independent variables in this context as they are not the factors being intentionally changed or manipulated. Choice D, 'Root length,' is the dependent variable, as it is the outcome that is being measured or observed in response to the changes in the independent variable, temperature.

5. Which of the following is the positively charged subatomic particle found in the nucleus of an atom?

Correct answer: B

Rationale: The correct answer is B: Proton. Protons are positively charged subatomic particles found in the nucleus of an atom. They have a mass of approximately 1 atomic mass unit (amu) and a charge of +1. The number of protons in an atom's nucleus determines the atomic number of the element, which is a unique identifier for each element. Choice A, Electron, is incorrect as electrons are negatively charged particles found outside the nucleus. Choice C, Neutron, is incorrect as neutrons are neutral particles found in the nucleus. Choice D, Quark, is incorrect as quarks are elementary particles that combine to form protons and neutrons, but they are not the positively charged particle found in the nucleus of an atom.
