I believe step 4, because in mitosis it creates 2 diploid cells
C. Shield Volcano.. think of Hawaiian volcanoes,they are basaltic eruptions, very effusive and unexplosive and are characterised by slow lava movement and very little tephra from the eruption. The basalt erupted is very hard, dense rock and so can be built up easily.
Aerobic respiration produces more ATP than anaerobic respiration because aerobic respiration occurs when oxygen is present and is then able to produce ATP as normal with a profit. However, anaerobic respiration has a lack of oxygen, which leads to either fertilization, only producing enough ATP to keep the cycle going and the cell surviving, (not creating any excess/profit ATP).
There are more different nutrients than meat.
