heat definition In physics, a form of energy associated with the movement of atoms and molecules in any material. The higher the temperature of a material, the faster the atoms are moving, and hence the greater the amount of energy present as heat.
Cilia (singular: cilium) are microscopic, hair-like structures that extend outwardfrom the surface of manyanimal cells. These structures are important in the cell cycle and replication, and cilia play a vital part in human and animal development and in everyday life. A typical cilium is between one and ten micrometers long, and usually less than one micrometer wide.
In antiquity, Cilicia (/sÉªËlÉªÊiÉ/) was the south coastal region of Asia Minor and existed as a political entity from Hittite times into the Armenian Kingdom of Cilicia during the late Byzantine Empire.
