Many essential nutrients are transported into plant cells through cotransport with H­+, which flows back into the cytoplasm. Proton pumps in the cell membrane of plant cells actively pump H+ into the extracellular space using energy from ATP hydrolysis. If a toxin that inhibits the plant proton pump is applied, which of the following would be true?

The sodium-potassium pump would cease to operate.
There would be more potential energy outside the cell than inside.
The electrochemical gradient across the cell membrane would be depolarized.
The cotransport of solutes against their concentration gradients would be enhanced.

Hunting in the darksome fish rely on senses beyond sight. in the darkness of the marianas trench, a fish called the rattail has an extremely sensitive sense of smell. the fish uses scent, rather than sight, to steer toward food. once it's near food, the rattail uses a special organ on the bottom of its chin to guide itself by feel.marine snowone staple of the deep sea diet is "marine snow," flakes of organic, edible substances that sink down from the upper ocean. animals at the ocean's bottom find sustenance in everything from the bodies of dead creatures to fecal matter. marine snow is diverse enough to support numerous species. for instance, several species of snails and worms feed exclusively on deceased whales.microorganismsthe deep sea is an intricate ecosystem, and even the ocean floor itself plays a part. hydrothermal vents are cracks in the sea floor where erupting magma mixes with ocean water to produce plumes of hot, sulfur-rich chemicals. some microbes can use these chemicals for energy, sustaining their existence and that of the animals who depend on their roles in the deep sea food chain.

3. is true i think i should be right
