Away that advancement in technology improve humans ability to measure air quality and protect human health.

There are many technologies that are being developed to lessen pollution. The only problem is how to support these technologies from the research being conducted down to commercializing them while making sure that they fulfill the development in air quality they are asserting. Some of these technologies are the exerting treatment of photo-catalytic to roads for the reducing of NOx and PM pollution,  the “Smog Free Tower” that was designed by a Dutch design company which can purify the air by sucking the pollution then lets out clean air, another example is the use of “liquid air” that do not create emissions on the road.

equal distribution i think.

the answer would be 2, if crossing over doesn’t occur 2 out of 4 of the daughter cells will have that allele.

hope this : )
