I need help answering this.

1) describe the physical layout of the ocean floor ? 2) explain how the dumbo octopus swims differently than other octopus species and why this would be an advantage in the aphonic zone . 3) why are the types of organisms that live at each underwater hot vent so dramatically different ?

How does climate change cause the ocean's thermohaline current to slow down?

Which of the following is a pure substance? airbloodcopperwood
