The 75% energy which does not do any useful work gets dissipated as thermal energy in gasoline engines.
Explanation:
The efficiency of any engine like gasoline engine is the ratio of work done in contrast to heat or energy provided.
Gasoline engines are internal combustion engine. The thermal efficiency is calculated of these engines.
work done or efficiency= 
or heat absorbed is divided by heat used in doing work
the friction and in other forms heat gets lost.
In gasoline engine about 65 to 75 % heat gets emitted without any useful work done. The heat gets lost in friction, air turbulence, noise and work input to turn on the engine. After the dissipation of heat in it only 25% is used up by vehicle having gasoline engines.
The correct answer is "<span>they can develop into most types of human cells".
Stem cells are cells that are undifferentiated to what function they may serve, depending on the tissue where it will develop in to. In the context of brain tissue implants, these stem cells can develop into brain cells or nerve cells or neurons which comprises the functional brain tissue; this is clinically significant as neurons are not capable of replacing themselves if damaged.</span>
B. Independent meaning by itself. Dependent meaning together, or not by itself, and since both are going 60mph and they both stop it’s dependent because they’re depending on each other to stop.
Artifact selections benefits humans by helping us learn what had happened in the past.
It has something to do with the combination of behavioral, biological, and cultural reason.
