Answer:
Plant cells deal with osmosis by being enclosed in a cell wall.
Animal cells use active transport systems to deal with the problem of osmosis.
Fresh water protists have contractile vacuoles to deal with osmosis.
Many bacteria have cell wall to protect them from osmosis.
Explanation:
Plant cells have a rigid cell wall. If a plant cell is places in a place where the conditions are hypotonic, then the cell will tale up water by osmosis but the cell wall will prevent it from bursting. This condition is termed as the cell being 'turgid'.
As animal cells do not have the rigid cell wall, they use the mechanism of active transport system to stop the cell from bursting during osmosis. In this process, ions are moved out of the cell so that the pressure in the cell due to osmosis can be reduced.
Fresh water protists have a structure present in them called as the contractile vacuole. The contractile vacuole has the capability to remove any excess water from the cell as well storing water if there is not enough water.
Bacteria have peptidoglycan cell walls to prevent osmosis.
I believe the answer is Proteins, DNA, fats, and starch
Answer:
Hope ur referring to the nitrogen cycle, but here goes: basically, u can start anywhere in the nitrogen cycle to describe what happens to that nitrogen. For instance, you can start in the atmosphere. Nitrogen makes up a considerable amount of the Earth's atmosphere. This nitrogen is fixated by nitrogen-fixating bacteria and is converted into ammonia, a form that can be absorbed by organisms. This enters into the ecosystem. When plants/animals that have nitrogen in their systems die, the nitrogen is returned into the soil. Some plants cannot absorb ammonia however. So, a process known as nitrification also takes place. This is when ammonia is then converted into substances known as nitrites and nitrates, which are then absorbed. Lastly, denitrifying prokaryotes convert nitrates back into atmospheric nitrogen. Thus is the cycle.
