One of the greatest proofs of evolution is the existence of fossil records.

Evolution refers to the gradual changes that took place in living organisms over time. One of the greatest evidences of evolution is the existence of fossil records.

Homologous Body Structures are the structures that have different mature forms but develop from the same embryonic tissues. It is a true statement that the wing of a bat, human arm, and leg of a turtle are examples of Homologous Body Structures.

The  traces of homologous organs in other species in which they no longer serve a function are called vestigial organs. The appendix in humans is a vestigial organ.

It is a true statement that in their early stages of development, chickens, turtles and rats look similar, providing evidence that they shared a common ancestry.

mountains can affect the climate of nearby lands. in some areas, mountains block rain, so that one side of a mountain range may be rainy and the other side may be a desert. much of airborne moisture falls as rain on the windward side of mountains.

explanation:

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.
