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 relationship between the structure and function of the nucleusis that the nucleus is an enclosed organelle and is large enough tohold the DNA. This is important because the nucleus must hold andprotect the cells DNA.
People refer to "Darwin's finches" from time to time as a symbol of evolution in the Galapagos Islands, but the father of evolutionary theory actually dropped the ball on those birds, collecting better details on mockingbirds, tortoises and other species.
Charles Darwin's observations, notes and collected organisms from the Galapagos Islands during his 5-year voyage on the Beagle resulted in his theory of evolution by natural selection, one of the best substantiated theories in the history of science.
He collected several finch species, including the warbler finch, sharp-beaked finch, ground finch, small tree finch, large tree finch, common cactus finch and large ground finch.
Answer:
The main purpose of everything that exist world is to create more suitable and better environment for future.
Explanation:
- As humans are the most developed species in the globe because they have the power to evaluate and conceive the activities going on in the surrounding.
- The most valuable thing we humans have is the consciousness i.e. we know how things work and can modify it.
- By using this awareness ability we have been in the race of evolution through millions of years making our environment more advanced and better.
