Eukaryotic cells have a nucleus. They can be single or multi celled.
Prokaryotic cells do not have a nucleus or membrane surrounded organells.
A desert would be a good example because there is no exact source of water there unless you are in a specific one.
The cell consists of many different cell organelle because it is just like the human body. The human body has many organ systems working and performing different functions to keep us alive. Similarily, even cells have different organelle performing different functions.
Uplift occurs are converging tectonic plate boundaries and at faults with compressional forces. As two tectonic plates collide, usually, the continental plate os folded due to the pressure hence causing uplift. At reverse faults, the compression causes the earth’s crust to uplift causing a hanging wall over the footwall.
Subsidence also occurs at convergent plate boundaries. The oceanic plate is usually the one that subsidies under the tectonic plate during the collision because it is heavier. SUbsience also occurs at normal faults where the two crust moves away from each other causing a chunk of the crust to subside. The hanging wall goes lower in elevation in comparison to the footwall.
The organisms who have only a cell wich are called monocellular living things and pluricellular living things.
