A river delta is a landform that forms from deposition of sediment carried by a river as the flow leaves its mouth and enters slower-moving or standing water. This occurs where a river enters an ocean, sea, estuary, lake, reservoir, or (more rarely) another river that cannot transport away the supplied sediment.Despite a popular legend, this use of the word delta was not coined by Herodotus.his alluvium builds up to form the river delta. When the flow enters the standing water, it is no longer confined to its channel and expands in width. This flow expansion results in a decrease in the flow velocity, which diminishes the ability of the flow to transport sediment.
All the different types of sex cells undergo meiosis while mitosis only occurs in no sex cells or what is known as somatic cells. Spermatozoa and ova (also known as gametes) are the two most important types of cells that undergo mitosis and meiosis.
Mitosis and Meiosis describes the process by which the body prepares cells to participate in either asexual or sexual reproduction to make an entire organism. Examples of Mitosis and Meiosis Mitosis is the reproduction of skin, heart, stomach, cheek, hair etc. cells. These cells are Autosomal cells. This is also a form of Asexual reproduction, where one organism or cell reproduces itself. Some organisms that reproduce asexually are hydra, bacteria, and single celled organisms.
