The answer is: pseudostratified ciliated columnar epithelial cells.
We can find these type of cells in the upper part of the trachea and bronchi, and through the whole upper respiratory tract (nasal cavity included).
Their job is to produce a mocous secretion (look up <em>cilia</em>) help us to stop external, microscopical, materials from entering our lungs, and so we can sneeze and cough them away.

2 .When the flashlight is turned on, the chemical energy is first transformed into electrical energy and then into light energy. CHEMICAL bonds. It is released during a chemical reaction (change).
3.BATTERY CONSISTS OF CHEMICAL ENERGY. WHEN OUR RADIO IS OPERATED BY INSERTING BATTERY INTO IT,CHEMICAL ENERGY IN BATTERY IS CONVERTED INTO SOUND ENERGY AND THUS WE HEAR SOUND FROM THE RADIO.
4. When a candle burns the energy transformation that takes place goes thus: it transforms chemical energy(wax)to heat and light energy it transforms chemical energy to heat energy which is later transformed to light Potential Energy is converted to Kinetic energy. ... The flame is in the form of light energy .
5.Electric stoves convert electrical energy into heat energy. An electric stove plugged into a wall outlet uses the electrical energy to flow into the burners on the stove top and as the electric charges go through the burners the electrical energy is transformed into thermal energy.
