The second largest crater in the world was formed by the impact of a comet according to a 2014 study by researchers in Canada and Ireland. Colliding with Earth almost 1.85 billion years ago, the estimated diameter of the crater is 81 miles (130 km).
How big is a bacteria compared to a human cell? The size of a typical bacterial cell is 0.5-5.0 micrometers, a average human cell is 10 micrometers.8 people found this useful.Edit.he consensus among biologists is that only 5 to 10% of the trillions of cells in our bodies are human. The rest are alien cells: yeast, fungi, bacteria, viruses.
Overview. Bacteria cells function quite differently from human cells, from the function of the cell as a whole, right down to the individual structures in each cell. Bacteria exist in nature as individual cells.While some bacteria work together in a group, no bacteria forms multicellular tissues.acterial Cell Function. In the grand scheme of things, the function of each bacterial cell begins and ends with collecting enough nutrients to survive. Bacterial cells consist of a phospholipid bilayer, and in some cases a layer of peptidoglycan.
