27. which two wave properties are related?\namplitude and wavelength\nfrequency and pitch\namplitude and pitch\nfrequency and amplitude\n\n28. what is one way to mitigate damage done by earthquakes?\nmeasuring the magnitude of the waves during an earthquake\nassessing damage done after the earthquake\nstudying earthquake waves and ways to predict them\nbuilding structures that can withstand earthquakes\n\n29. what can cause dna sequences to change over time?\nmutations\ncytochrome c\nbiochemistry\namino acids\n\n30. which suggestion would not make a slide show presentation more effective?\nkeeping a consistent font, color, and background\nusing images to reinforce information\nonly using a few words on each slide\nusing transitions to animate the words on the slides

Answer

# Answer: 27. B. frequency and pitch 28. D. building structures that can withstand earthquakes 29. A. mutations 30. D. using transitions to animate the words on the slides # Brief Explanations: 27. Frequency determines pitch in sound waves. 28. Building quake - resistant structures mitigates damage. 29. Mutations change DNA sequences. 30. Over - using animations can be distracting.
