Answer:
begins in the mouth(ptyalin converting carbohydrate to maltose), stops in the illeum (secretion of amylase) and Is completed in the body cells(to release energy)
Red blood cells are disc shaped. It is thought one factor that allows them to have this shape is because they do not have a nucleus. This tends to increase amount of space inside the cell for hemoglobin.
They have a flexible disc shape which helps increase the surface- to- area volume ratio which enables oxygen and carbon dioxide to diffuse across the red blood cell's plasma membrane more readily.
Their disc shape also enables them to squeeze through tiny capillaries that are half their size .
primary production is the synthesis of organic compounds from atmospheric or aqueous carbon dioxide.
The Endoplasmic reticulum is a series of pipes and it moves in the cell. Without the E.R., the protein factory (ribosomes) would not be able to ship the proteins and cells would starve to death. Hope this helped!
