Answer:
Bioluminescence
Explanation:
In the deep oceans, the sea cucumbers and polychaete worms use the bioluminescence for defense against predators and to find or attract prey by glowing so the predator can easily see it's glowing skin.
Answer:
Oxygen.
Explanation:
Oxygen molecule that is produced in the light dependent reactions. This shutting down of linear electron flow greatly affected the production of oxygen. Photosystem II gains replacement electrons from splitting of water molecules into hydrogen ions (H+) and oxygen atoms so if the electron flow is disturbed then oxygen production is greatly affected.
Answer:
D
Explanation:
The correct answer would be that the origin of all cells can be traced to previous or pre-existing cells.
According to the cell theory which is made up of three parts;
- <em>The cell represents the basic unit of all life.</em>
- <em>All living organisms are made up of cells.</em>
- <em>Cells do not arise spontaneously, but only from pre-existing cells.</em>
Hence, the discovery that the origin of all cells is traceable to previously existing cells supports the latter part of the cell theory.
The correct option is, therefore, D.
Answer:
1. ridges and trenches (either answer is acceptable)
2. mid-atlanitc
3. subduction zone
4. molten
5. oceanic trenches
Explain:
6. Rocks in the ocean eventually get subducted back into earths mantle due to slab pull. New rocks form at mid-ocean ridges as ridge forces two plates to diverge.
Answer:
Hilda and her family are going on a sailing trip this summer, and Hilda is especially interested in spotting dolphins. In which zone of the ocean is Hilda most likely to spot dolphins? Hilda and her family are most likely to spot dolphins in the PELAGIC zone. To view shorebirds and crabs, Hilda should move towards the INTERTIDAL zone.
Explanation:
The Pelagic Zone
It is any water in an ocean or lake that can not be said to be positioned in proximity to the shore or in proximity to the bottom (the shore and the bottom are two distinct zones with a completely different properties.
Divisions of the Pelagic Zone
It can be grouped into subzones based on depth, we have the epipelagic, close to the top of the zone which as light been present, and the abyssopelagic, is nearer to the bottom with light being absent.
The intertidal zone
Its found between the high tide (upper limit) and low tide lines (lower limit), majorly on the beach at the water's edge.
The major attribute of the intertidal zone is that it is immersed with water at high tide and is in exposure to the air at lower limit. The intertidal zone is usually undergoing alterations leading to organisms that are uniquely adapted to strive there.
Organisms found in this zone are sea stars, crabs, mussels, barnacles, and various corals as they well situated to strive immersed in water and a region of their lives open air at lower limit.
