Because of genetic variation
Answer:
Perceptual region
Explanation:
A perceptual or vernacular region is defined by feelings and prejudices that may or may not be true I believe:)
<span>Thermal energy is transferred from hot places to cold places by convection. Convection occurs when warmer areas of a liquid or gas rise to cooler areas in the liquid or gas. Cooler liquid or gas then takes the place of the warmer areas which have risen higher. This results in a continous circulation pattern. Water boiling in a pan is a good example of these convection currents. Another good example of convection is in the atmosphere. The earth's surface is warmed by the sun, the warm air rises and cool air moves in.
</span><span>Convection is the movement of heat through gases or liquids. Heat from the sun heats the air which can account for A and D, but a lot of the Earth's heat is distributed by the ocean. Water has a high specific heat which can absorb a lot of heat in one place, and distribute it in a colder place evening out the Earth's temperatures a bit.

So, the answer would be
<span>through the greenhouse effect
And could also be </span><span>through the movement of winds and currents</span>

Answer:
Becoming cleaner comes with an increased cost of electricity. According to this graphic the increase in the UK annual cost of energy between 2007 and 2015 for an average house was 37%
Explanation:
According to the graph, the average yearly cost of energy in the average UK household in 2007 was £954, or around $1239 USD, and it rose to £1311, or around $1703 USD in 2015. So, the energy bill increase on average by £357 or around $464 USD, which represents an increase of 37%.
£954 = 100%
£357 = X
X= £357 * 100% / £954
X = 37.42 %
The average monthly bill will then be around £109, or $142 USD, which, compared to the US, it is slightly more expensive (21% more expensive), since according to the US Energy Information Administration, the average monthly electric bill for an average house in 2017 was $111 USD.
