1 = Tt; 2 = tt; 3 = Tt; 4 = tt
1 = Tt; 2 = Tt; 3 = Tt; 4 = Tt
1 = Tt; 2 = Tt; 3 = tt; 4 = tt
1 = Tt; 2 = tt; 3 = tt; 4 = tt

Of seawater increases with decrease in the temperature. therefore, the cold water sinks to the deeper layers at the bottom

Are the earth's ocean floor and continents the same age geologically? why or why not?

Hydrilla (hydrilla verticillata) is an invasive aquatic plant and one of the most serious aquatic pests in florida. hydrilla has already been introduced to hundreds of bodies of water throughout florida, hydrilla is difficult to control because it grows rapidly and survives in many different water depths and conditions. hydrilla • describe how hydrilla affects native plant and animal species. include both a biotic and an abiotic limiting factor. • suggest one biotic and one abiotic recommendation that could slow the spread of hydrilla
