Question

dandelion seeds each have an umbrella - like structure at their top. this structure allows the seeds to be carried by the wind.
a scientist claims that this umbrella - like structure increases the dandelion plants reproductive success.
which observation would best support the scientists claim?
choose 1 answer:
a dispersed seeds grow into plants that produce less pollen than non - dispersed seeds.
b dispersed seeds are more likely than non - dispersed seeds to grow into new plants and survive.
c dispersed seeds attract more flying pollinators than non - dispersed seeds.

Explanation:

Reproductive success refers to the ability of an organism to produce offspring that survive and reproduce. If dispersed seeds (due to the umbrella - like structure) are more likely to grow into new plants and survive, it directly supports the claim that the structure increases reproductive success. Option A mentions less pollen production which is not related to reproductive success. Option C talks about pollinators being attracted to seeds, but seeds are not the stage where pollination occurs (pollination is for flowers).

Answer:

B. Dispersed seeds are more likely than non - dispersed seeds to grow into new plants and survive.
