A gasoline car typically uses a spark-ignited internal combustion engine, rather than the compression-ignited systems used in diesel vehicles. In a spark-ignited system, the fuel is injected into the combustion chamber and combined with air. The air/fuel mixture is ignited by a spark from the spark plug.
Answer:
gain, rather than lose, heat by radiation.
Explanation:
The body is can lose the heat by evaporation, radiation, conduction, and convection. The sun transfers the heat on the earth through radiation which we absorb and our body temperature rises. The loss of heat from the body through radiation occurs normally when the air temperature is below 20-degree Celcius.
But in tropical regions, the temperature is very high so the gain of heat by radiation is more than the loss of heat by radiation which can lead to heatstroke in those people who do not have sweat glands because in this condition 85% of heat can be lost by sweating.
A gene mutation is a permanent alteration in the DNA sequence that makes up a gene, such that the sequence differs from what is found in most people. ... Acquired mutations in somatic cells (cells other than sperm and egg cells) cannot be passed to the next generation.
