Morning glories are plants that have a large amount of variation in the genes for flower color. When a white flower appears in a population independent of the trait for white flower color, what is the MOST likely source? a. genetic mutation
b. selective breeding
c. genome duplicating
d. sexual recombination

i believe the correct answer from the choices listed above is the first option. the scientists need to look at the   validity of data, claims, hypotheses, and observations before  developing an argument. they base their arguments on facts that are present and they make sure they have proofs. 

explanation:

oxygen = 21% of the atmosphere

nitrogen = 78%

carbon dioxide = 0.1%

argon =0.934%

idk im sorry.
