Answer:
Semiconductors
Explanation:
Semiconductors are materials whose main characteristic is that they can act as conductors or as insulators depending on some conditions such as temperature or the electric field.
There are also chemical elements that have semiconductor capacity, for example silicon.
For this property, semiconductors are widely used for in electronics, among these applications is the manufacture of devices such as transistors, which are electronic divices that allow or disable current flow.
It can't. Acceleration IS a change in velocity.
Answer:
The epithelial cell shape and stratification are related to its function. For example, the skin is specialized to act as a "physical" barrier to the outside world. This barrier is both structural (multi-layered) and chemical in nature. Another example is the cells that make up the tubular elements of the kidney.
