Answer the following question given this paragraph: Electromagnetic radiation is energy that travels in waves across space as well as through matter. Most of the electromagnetic radiation on Earth comes from the sun. Like other waves, electromagnetic waves are characterized by certain wavelengths and wave frequencies. Wavelength is the distance between two corresponding points on adjacent waves. Wave frequency is the number of waves that pass a fixed point in a given amount of time. Electromagnetic waves with shorter wavelengths have higher frequencies and more energy. Q: What type of energy travels in waves across space as well as through matter? Choices: - kinetic energy - mechanical radiation - thermal energy - electromagnetic radiation A:
electromagnetic radiation

Answer the following question given this paragraph: Crests and troughs are the high and low points of a transverse wave. Q: Crests and troughs are the high and low points of a what? Choices: - darker wave - rupture wave - heat wave - transverse wave A:
transverse wave

Answer the following question given this paragraph: Notice the differences in the species' beaks in Figure 18.13. Evolution in response to natural selection based on specific food sources in each new habitat led to evolution of a different beak suited to the specific food source. The seed-eating bird has a thicker, stronger beak which is suited to break hard nuts. The nectar-eating birds have long beaks to dip into flowers to reach the nectar. The insect-eating birds have beaks like swords, appropriate for stabbing and impaling insects. Darwin's finches are another example of adaptive radiation in an archipelago. Q: Evolutionary adaptation is evidenced by different shapes of what structures in birds with different food preferences? Choices: - claws - Stomach - necks - beaks A:
beaks
