The natural gas is composed of methane, butane, propane and a small amount of iso-Butane.
These all are organic compound (alkanes) and burn in presence of the oxygen to give carbon dioxide. The burning of the alkanes is type of exothermic reaction, which means they liberate heat energy on reaction. The enrgy is released due to the braking of the bond and the formation of the new bonds.
Hence, it can be concluded the chemical taking place at the time of burning of these gases gives off the energy.
Average kinetic energy is directly proportional to temperature, so when kinetic energy decreases so does temperature and when kinetic energy increases so does temperature.
The answer is, <span>B) Eukaryotes

Answer:
Elderly people are more likely to have cognitive deficits as part of brain senescence.
Explanation:
Aging is a gradual and inevitable process throughout living beings. Along with this aging occurs brain senescence, which is a process of losing brain connections due to lack of intellectual activities.
While this is not a rule, the elderly are the most common people going through the brain senescence process. For this reason, the elderly are also the most common people to develop cognitive deficits.
Cognitive Deficit consists of the learning disability that some people have and that ends up limiting their life in many ways. The problem is directly related to the mental capacity of information assimilation, which causes the individual to develop intellectual limitations.
