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.
This process, repeated over and over, forms low ridges or mounds known as natural levees (pronounced LEH-veez). Levees built by humans along rivers in an effort to control flooding are known as artificial levees. Natural levees are composed primarily of gravel and sand. They are steep on the side facing the stream channel and gently sloping on the other side. Varying greatly in size, levees may be several feet in height and up to a mile or more in width.
