TEAS 7 science quizlet

1. Which types of waves are capable of interference and diffraction?

Correct answer: D

Rationale: Both longitudinal and transverse waves are capable of interference and diffraction. Interference occurs when two or more waves overlap and combine, either constructively (increasing amplitude) or destructively (decreasing amplitude). Diffraction is the bending of waves around obstacles or through openings, which can occur with both longitudinal and transverse waves. Choice A is incorrect because only stating longitudinal waves can undergo interference and diffraction is inaccurate. Choice B is also incorrect as transverse waves, not just longitudinal waves, can exhibit these phenomena. Choice C is incorrect because electromagnetic waves are a broad category that includes both longitudinal and transverse waves, so it is not exclusive to either type. The correct answer is D because both longitudinal and transverse waves can demonstrate interference and diffraction.

2. What is the scientific name for the common housefly?

Correct answer: A

Rationale: Musca domestica is the scientific name for the common housefly. This species is known for being a common pest found in and around human habitations. Drosophila melanogaster (option B) is a species of fruit fly commonly used in genetic research. Apis mellifera (option C) is the scientific name for the western honeybee. Anopheles gambiae (option D) is a species of mosquito known for being a vector of malaria.

3. Which of the following best defines the term amphoteric?

Correct answer: B

Rationale: An amphoteric substance can act as both an acid or a base depending on the environment. It can donate a proton (act as an acid) or accept a proton (act as a base), showing versatility in its behavior. Choice A is incorrect as it describes an electrolyte rather than an amphoteric substance. Choice C is incorrect as it defines an acid based on the Brønsted-Lowry Acid-Base Theory. Choice D is incorrect as it specifically refers to a substance donating a proton in a neutralization reaction, not capturing the dual behavior of an amphoteric substance.

4. Which human body system is correctly matched with its function?

Correct answer: B

Rationale: The circulatory system is responsible for the transportation of oxygen from the lungs to all the body's cells and tissues, as well as removing carbon dioxide from the cells and transporting it back to the lungs to be exhaled. This process is crucial for cellular respiration and the exchange of gases necessary for bodily functions. Choice B accurately matches the role of the circulatory system by describing its function of transporting oxygen to cells and removing carbon dioxide, which is essential for maintaining proper cellular activities. Choices A, C, and D are incorrect because they do not accurately match the body system with its function. The respiratory system primarily involves the exchange of gases in the lungs, not transportation to cells; the lymphatic system deals with immunity through the production of antibodies, not gas exchange; and the endocrine system's main function is hormone regulation, not the transport of gases.

5. Which digestive enzyme is primarily responsible for breaking down proteins?

Correct answer: A

Rationale: The correct answer is A, Pepsin. Pepsin is primarily responsible for breaking down proteins in the stomach. It is produced in an inactive form called pepsinogen, which becomes activated by the acidic environment in the stomach. Pepsin functions by breaking down proteins into smaller peptides, which are further digested by other enzymes in the small intestine. Lipase is responsible for breaking down fats, amylase for carbohydrates, and maltase for converting maltose into glucose. Therefore, choices B, C, and D are incorrect as they are associated with breaking down fats, carbohydrates, and converting maltose, respectively, not proteins.
