Answer 2

1 - A ground level plant develops curling tendrils that wrap around other objects so it can "climb".

This is a species changing over time as it was originally a ground level plant but began to climb higher.

2 - Over many generations.

This is because diversity takes time and has to be integrated through generations; for instance, marriage. In a family, it becomes more diverse after the next generation as each generation is likely to marry someone of another ethnicity and allow the family tree to become more diverse.

3 - Mutate or Survive

It depends on what it means by mutate - develop a mutation to make it adaptable? If that's the case, then mutations within the DNA would be a result of adaptation and increase survival. Otherwise, survive is the obvious answer as adaption allows for species to move around and live longer.

Hope this helps!
