Answer:
The three seabed habitats: vents and seeps, trenches and seamounts. The phytoplankton develops in the area exposed to the sunlight to take the elements dissolved in the sea water, including carbon dioxide, to create new cells and are responsible for about half of the inhabitants of the planet of the photosynthesis and production of oxygen. It is found mainly in the surface and lands on the seafloor as dead cells, still carrying the carbon dioxide, while maintaining the balance of oxygen/carbon dioxide in the ecosystem.
The answer is 4, because if the ants smell the same dead smell on this particular ant in the colony, their initial reaction is to eliminate it. The chemical sprayed upon the ant acts as a stimulus for a particular behavior.
Mitosis
because the cell split into two identical copies!
