Explanation:
2. <u>Science has shown that humans can adapt to changing environmental conditions over time such as with vitamin D self-synthesis, skin tone, and geographic location. Living in a northern climate such as Utah leads to poor self- synthesis much of the year. Having a deficient vitamin D intake level occurs from not consuming seafood, fortified foods, or mushrooms and increases my risk for osteomalacia. </u>

Mutations may be either beneficial or deleterious; they are maintained within cells, as they form new traits called alleles. Beneficial mutations may confer traits that increase the fitness of a species, along with ensuring survival by conferring a protective advantage- these phenotypic differences between organisms are called adaptations.
Further Explanation:
During the process of cell division, spontaneous changes within the genome can arise. These mutations are errors occur when copies of the DNA within the cell are made; mutations may range from small changes called single nucleotide polymorphisms, to large scale deletions, and additions which span multiple genes. There are two types:
- somatic: these only occur within certain cells, and arise from environmental factors such as UV light
- hereditary: occur within germ cells of the parent and later the fertilized egg which forms a zygote; these are present within all cells of the new organism.
During reproduction, other events, such as crossing over during mitosis and meiosis, mutations lead to increases in genetic variation. This variation refers to the genetic characteristics present within a species.
