Gregor Mendel took it upon himself to force cross-pollinate his plants. He physically took pollen from one plant and brought it to the pollen of a different plant.
i believe that your talking about culture apportion if not i'm sorry but if you are ill give you some examples.
1. A white person trying to be black like darking their skin color and getting hair styles that are for black people like dreads and cornrows.
2. people that are trying to be Korean and Japaneses like whiting their skin color and trying to change the shape of their faces and the use products to make them look Japanese when they are not.
I believe that you got an idea from the 2 examples i just gave you how about you come up with the 3rd example. Again i'm really sorry if ur not talking about culture apportion.
Answer:
Solar energy
Explanation:
Solar energy is renewable and a very cheap energy source that can easily be harnessed for a wide range of uses domestically and industrially.
Solar energy is sourced from the sun. Nuclear fusion within the sun releases a massive amount of energy into the solar system. The sun furnishes the solar system with insolation which can be used by living organisms and can be converted to other sources of energy.
This energy source is free and very much available almost all year round.
