Selective breeding (also called artificial selection) is the process by which humans breed other animals and plants for particular traits. Typically‚ strains that are selectively bred are domesticated‚ and the breeding is normally done by a professional breeder. Bred animals are known as breeds‚ while bred plants are known as varieties‚ cultigens‚ or cultivars. The cross of animals results in what is called a crossbreed‚ and crossbred plants are called hybrids. In animal breeding techniques such

The plasma or cell membrane exhibits ability for the cell to discriminate in its chemical exchanges with its environment and this makes cell membrane fundamental to life. This property can only be possible because of the cell membrane’s selective permeability (Campbell and Reece‚ 2002). The structure of the membrane can be best illustrated by the fluid mosaic model where the membrane is said to be a fluid structure with various proteins embedded in or attached to a bilayer of phospholipids (Campbell

The function and permeability of the cell membrane depends on its whole structure. When destroyed‚ the permeability of the cell membrane is disrupted causing cellular contents to leak out. When cells are cut‚ the cell membranes are mechanically

The plasma membrane is a fluid phospholipid bilayer. The outside of the bilayer is hydrophilic portions of porteins and phospholipids because they are exposed to water. This results in a stable membrane structure. Inside the bilayer hydrophobic portions of proteins and phospholipids because the inside of the bilayer is nonaqueous. the proteins bob in the fluid bilayer of phospholipids. The proteins also vary in structure and function. There are teh integral proteins; transmembrane
