B. Variation allows some individuals to interbreed with other species and so evolve over time

C. Varation allows some indivudals to move to new enviorments and develop into new species.

Answer 1

i think it might be A or B

Answer 2

Answer 7

small variations mean some will do better than others and they will get to reproduce.

For example, giraffes with the longest necks can reach more leaves high in the trees. If there are a shortage of leaves, the giraffes with the longest necks will be able to eat more so will survive and reproduce (the giraffes with shorter necks will be at a disadvantage). So the babies of the long necked giraffes will have long necks also, and so will their babies - can you see how over time the giraffes will evolve to have longer necks?
