(A) ANSWER: 0%. A homozygous dominant seal would be "WW" (homozygous dominant = 2 CAPITAL letters).
The process of genetic engineering has been utilized to create this drug.
Genetic engineering is the artificial modification of DNA or other nucleic acid molecules in order to alter an organism’s characteristics in a certain way using biotechnology. Genetic engineering is used by scientists to improve or change the genetic makeup of an individual organism and it involves the transfer of genes to create ameliorate organisms.
Answer:
The correct answer is: geography and UV radiation.
Explanation:
Skin variation occurred thanks to evolution, and was driven as a consequence of the geographical location of different populations of humans.
The humans that lived in hot and sunny places, closer to the equator, where much more exposed to the sun's ultraviolet radiation. In order to survive the amount of UV lights that they were exposed to, new humans in those regions were being born with a darker skin tone, which was rich in melanin (a brown pigment that protects us from the sun radiation).
Contrary to these humans that lived in the tropical areas, the humans that populated the areas that were closer to the poles, developed much lighter skin as a result of lower amounts of melanin in their skin. Since sun exposure in the poles is very limited, humans needed to receive as much as they could for the production of Vitamin D, and thus, their skins got lighter and less protected.
The biggest difference is the cause. The solar wind is a constant flow of particles from the sun's corona due to their high energy gained from the sun's interior, it's like being boiled off. CME's and flares are the result of “explosive” releases of energy from the sun's magnetic field. Solar flares and solar winds originate within the sun's atmosphere, but differ greatly from one another. Satellites on Earth and in outer space allow a look at solar flares, but you cannot see solar winds directly. However, the effects of solar winds reaching Earth appear to the naked eye when the aurora borealis and aurora australis electrify the night sky.
