D. Mutations involved the genetic variation of the bugs are random
The UV rays cause sun spots due to reaction from the radiation.
There are so many examples for that in different areas, like organic germanium compounds experiment carried out in our lab recently.
Here's one link: http://www.alfa-chemistry.com/products/organic-germanium-24.htm
One is the diversification
of food sources. Second is increasing agricultural
production by implementing good agricultural practices and adopting
contemporary technologies such as Genetically Modified Foods. The third is increased exports to these counties
with undefined populations. Fourth is embracing good agricultural land management practices such as reducing land
