Put the events in order to show how the global conveyor belt works. Assume that you are starting with cold water on the bottom of the ocean near Antarctica, and it is gradually starting to warm as it moves north. 1) Water reaches Norwegian Sea
2)Water warms and rises to surface
3)Water flows south to Antarctica
4)Water flows near surface
5)Water cools and sinks to the bottom

genetic variation can be caused by mutation (which can create entirely new alleles in a population), random mating, random fertilization, and recombination between homologous chromosomes during meiosis (which reshuffles alleles within an organism's offspring).

answer: grassland biomes are closer to the equator and receive more rain.

grasslands are biomes that are dominated by grasses rather shrubs and trees. savanna are biomes that exhibit grasses, shrubs and small tree as vegetation. grasslands are located near the equator of the earth. these are found in north america. savanna biomes are found in africa, south america, australia and india. grassland exhibit moderate climatic conditions, it receives   amount of rainfall higher than savanna.   therefore, savanna exhibit dry and hot climatic conditions.
