Answer:
The water we drink now was the same water the dinosaurs drank. Discuss how the water cycle makes this statement accurate. Include different parts of the water cycle and what processes help move the water through each part.
Answer:
Diffraction
Explanation:
Diffraction is the key explanation why we can hear sounds around corners but not see them. As compared to light waves, sound waves have much longer wavelengths, making diffraction effects much more visible. When the size of the object that the wave is diffracting around is about the same as the wavelength of the wave, diffraction effects become very visible.
Sound has a wavelength of 1 m, while light has a wavelength of 0.1 micro m. Reflection is a secondary reason. Sound waves bounce off walls in a specular way, allowing them to bounce around corners, but light bounces off walls in a diffuse manner.
hope this helps :)
I believe the correct answer among the choices listed above is the last option. Plants seemed to evolve in the order of bryophytes, gymnosperms,angiosperms. Bryophytes are mosses that lack vascular tissue. Gymnisoerm do not have seeds but have vascular tissue. Angiosperms have flowers and seeds for mating.
