Question

The graph below shows the stomata counts of plant species Rudbeckia hirta, also known as black-eyed Susan:

Which statement best explains the observed stomata counts in Rudbeckia hirta?
Changes in genes produced Rudbeckia hirta with different stomata counts.
Changes in gene expression help Rudbeckia hirta adjust to its environment.
O Mutations provided Rudbeckia hirta with a genetic advantage.
More than one gene determines the stomata count of Rudbeckia hirta.

Answer 1

Answer: B: Changes in gene expression help Rudbeckia hirta adjust to its environment.

Explanation: I just took this test :) this was the right one... the gradual decline shown shows a change in expression, resulting in fewer stomata, as the environmetal conditions change.
