Lysosomes reside in the cell as re-usable organelles and when cell division takes place each daughter cell receives a number of lysosomes. How this number is increased has not yet been elucidated. It is thought that the reservoir of chemicals in the lysosome can be âtopped upâ by supplies from the Golgi apparatus.
A levee is an embankment that helps protect the land from a floodplain. A levee is formed when floodwater deposits material on the banks of a river, which builds up over time â¦ . The embankment slowly erodes away which is making rivers and streams wider and it can sometimes create a v-shaped valley.
The history of man's attempts to control the Mississippi is full of both success and failure. Levees already existed when the first French trappers ventured into the wilds of Louisiana. These levees were formed naturally by the Mississippi's fluvial processes and tended to be no more than a meter or two in height. Building up these natural levees was the first solution to the flooding problem. In 1717, the first manmade levee system was started by Bienville, the founder of the city of New Oreans. The construction of the first levees, which reached only three feet in height, was completed in 1727.
