The sunâs surface vibrates from internal pressure waves reflecting off of the photosphere and passing through the solar interior. since these waves penetrate deep inside the sun, an analysis of the vibrations these waves cause at the surface can reveal unique information about the solar interior. the science of studying the vibrations on the surface of the sun is known as helioseismology. if you were a helioseismologist, which of the following observational methods could you use to obtain information about the solar interior? (a) determine the composition of the solar surface(b) measure doppler shifts in solar spectral lines(c) measure solar surface temperatures(d) determine the wavelengths and frequencies of individual pressure waves

Researchers determine that the biodiversity in a woodland region is declining. they identify two major threats to the region's biodiversity, a method to address each threat, and the expected outcome of each method. this information is shown in the table. a) reforestation would not benefit many species because most forest species live on the ground. b) reforestation would take the longest time to be effective because trees take several years to grow. c) biological augmentation would benefit only a few species because is is typically not very effective. d) biological augmentation would take less time to ve effective because it targets the majority of prey species.
