Artificial selection for similar traits occurred
Seeds were dispersed from birds across different continents
Many of these plant species are exposed to the same environmental pressures
The plant species are pollinated by the same insects
Organisms better suited to their environment survive easier and longer than those who aren't
Natural Selection
Adaption
Artificial Selection
Speciation

Which conclusion can best be drawn from the information given in the graph above?
trait for dark color is better for survival in a non-polluted environment.
trait for light color is better for survival in a polluted environment.
trait of color may be a favorable adaptation in one environment, but not in another environment.
What did Charles Darwin observe in finch populations of the Galapagos Islands off the coast of South America that proved as evidence that organisms are adapted to their environments
different species on different islands
all species on one of the islands
identical species on all the islands

Why does a cactus have shallow roots while other desert plants have deeper roots?
Shallow roots help to absorb water quickly before it evaporates.
A cactus does not need deep roots because it has a strong stem.
Other plants only want to take in water that is deep underground.
The water near the surface is much better for helping a cactus to grow.

Some desert plants produce groups of seeds in which only a small amount of them germinate each year. Which statement is true?
The plants are less likely to reproduce since all seeds don't germinate at the same time
The plants are more likely to reproduce because fewer total seeds germinate
The plants are more likely to reproduce because germinated seeds that die during droughts will only be a small portion of total seeds
The plants are less likely to reproduce because only a small portion of total seeds will germinate and grow into plants during wet periods
