Basically certain traits are going to give a better outcome for the animal the white rabbits living on white snow are going to be able to survive better than the brown rabbit and the population of brown rabbits will be reflected through the graph
Sucrose: glucose + fructose sucrose is a disaccharide made from glucose and fructose
glucose: C(sub 6)H(sub 12)O(sub6)fructose: C(sub 6)H(sub 12)O(sub6)sucrose: C(sub 12)H(sub 22)O(sub 11)a water molecule, H(sub 2)O gets removed which is why there are 2 less hydrogens and one less oxygen
C "fatty acids" is your answer
