which type of waves are capable of interference and diffraction

TEAS 7 science quizlet

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

A. Longitudinal waves only
B. Transverse waves only
C. Electromagnetic waves only
D. Both longitudinal and transverse waves

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 term for the tiny particles that make up atoms?

A. Protons
B. Electrons
C. Neutrons
D. Subatomic particles

Correct answer: D

Rationale: The correct answer is 'Subatomic particles.' Subatomic particles are the tiny components that constitute atoms, including protons, neutrons, and electrons. Protons and neutrons are located in the nucleus of an atom, while electrons revolve around the nucleus. Choices A, B, and C specifically refer to individual subatomic particles but do not encompass the complete range of particles within an atom.

3. What function do genes serve in the relationship between parents and offspring?

A. Genes enable hereditary information to be passed from parents to offspring.
B. Genes prohibit hereditary information from being passed from parents to offspring.
C. Genes enable environmental factors to affect parents and offspring.
D. Genes serve no function in the relationship between parents and offspring.

Correct answer: A

Rationale: Genes play a crucial role in passing hereditary information from parents to offspring, ensuring the transmission of genetic traits. This process forms the basis of inheritance and genetic continuity between generations. Choice B is incorrect as genes do not prohibit but rather facilitate the transmission of hereditary information. Choice C is incorrect because genes primarily transmit genetic information, while the influence of environmental factors is separate. Choice D is incorrect as genes are fundamental in genetic inheritance and the relationship between parents and offspring.

4. Which hormone deficiency can lead to stunted growth and developmental delays in children?

A. Estrogen
B. Testosterone
C. Growth hormone
D. Insulin

Correct answer: C

Rationale: The correct answer is C, Growth hormone. Growth hormone plays a crucial role in stimulating growth, cell reproduction, and regeneration in children. A deficiency in growth hormone can lead to stunted growth and developmental delays. Estrogen and testosterone are sex hormones that do not directly influence growth in the same way as growth hormone. Insulin primarily regulates blood sugar levels and is not the primary hormone responsible for growth and development in children.

5. Which of the following is NOT a component of the body's innate immune response?

A. Physical barriers like skin and mucous membranes
B. Phagocytes that engulf and destroy pathogens
C. Inflammatory response to isolate and contain infection
D. Production of antibodies specific to a particular pathogen

Correct answer: D

Rationale: The production of antibodies specific to a particular pathogen is a function of the adaptive immune response, not the innate immune response. Innate immunity involves nonspecific defense mechanisms like physical barriers, phagocytes, and inflammation, which provide immediate protection against pathogens without prior exposure. Antibody production is a characteristic of adaptive immunity, where the body generates specific antibodies in response to encountering a pathogen for the first time. Therefore, option D is the correct answer as it does not align with the immediate and nonspecific nature of the innate immune response.
