Jimmy held the end of a metal bar over a fire while holding on to the opposite end. after a few minutes, the end he was holding began to get very hot. which of the following processes correctly describes the heat traveling from one end of the bar to the other?

The heat is transferred by the process of conduction of heat.

Explanation :

It is given that, Jimmy held the end of a metal bar over a fire while holding on to the opposite end.    

After some time, the end he was holding began to get very hot.

The process of traveling heat from one end of the bar to the other end is called conduction. It is the process of transfer of heat by the interaction of particles and motion of electrons.

photosynthesis makes the glucose that is used in cellular respiration to make atp. the glucose is then turned back into carbon dioxide, which is used in photosynthesis. while water is broken down to form oxygen during photosynthesis, in cellular respiration oxygen is combined with hydrogen to form water.
