The warmer temperatures caused the polar ice caps to melt‚ and the increased amount of freshwater in the ocean disrupted the North Atlantic Current. The North Atlantic Current is what is responsible for the warm temperatures in the Northern Hemisphere. With the current disrupted the Northern Hemisphere went into an ice age. In real life‚ the

Commercial fishing became industrialized by the late nineteenth century‚ as technological innovations helped locate‚ catch‚ and process fish. In addition to fish living in natural freshwater or saltwater fisheries‚ fish cultivated in fish farms ’ ponds or tanks represented approximately one-fourth of the fish eaten in the world. Countries benefited economically with domestic trade and by exporting valuable fish. In the early twenty-first

Each individual cell is covered in a hardened frustule made from silica. They are both alike in that they are both protists. However‚ dinoflagellates are a part of a group called alveolates. They are most common in marine and freshwater phytoplankton. Some are heterotrophic. Diatoms‚ on the other‚ are a part of a group called stramenopiles. They are unicellular‚ photosynthetic algae with cell walls that contain silica. Dinoflagellates are a diverse group of flagellate
