Which statements are correct concerning the evolution model: • incorporates higher order life forms which parallel each other • only a few simple life forms give rise to new kinds of life which will increase in complexity • all life on earth developed from nonliving matter of natural unknown processes • each lower life form can be traced back only to the life form corresponding to a basic kind

Wetlands form where water and land meet. a lake with a wetland fringe can fill in with decayed plant and animal material to become a wet meadow. a pond can fill in to become a bog or fen. sediment can fill in a river marsh to become a swamp.flooding of coastal lowlands from rising sea levels has created broad coastal marshes that are protected from wave action by barrier islands or reefs. coastal wetlands also form when rivers deposit sediment as they reach the ocean. plants then take root and hold the soil firm against the forces of tides and waves.

Ecological footprint is determined by measuring carbon dioxide emissions for a given region.
