The most plausible hypothesis to explain why species richness is higher in tropical than in temperate regions is that a) tropical communities are younger. b) tropical regions have more available water and higher levels of solar radiation. c) warmer temperatures cause more rapid speciation. d) biodiversity increases as evapotranspiration decreases. e) tropical regions have very high rates of immigration and very low rates of extinction

Hope this helped!!

igneous rocks which formed by the crystallization of magma at the surface of the earth called extrusive rocks. they are characterized by fine-grained textures because the rapid cooling at or near the surface did not provide enough time for large crystals to grow.

the elements of art are the visual tools that the artist uses to create a composition. these are line, shape, color, value, form, texture, and space.

the principles of art and design are balance, contrast, emphasis, movement, pattern, rhythm, and unity/variety.
