Which statement is the best description of organism behavior?

D: the way an organism responds to the elements in its environment

Darwin's finches are often used to illustrate evolution. Evaluate the finch beaks shown in the picture. Choose ALL of the statements that correctly explain the evolution of finch beaks.

A) As the environment changed, the finches grew longer beaks to allow them to get food out of fruits.

B) Finches with longer beaks settled on the same island with smaller beaked birds. Over time, they bred, producing medium beaked birds that became more common in the population.

C) There are finches with different types of beaks in the population. During a drought, those with shorter beaks are not able to find sufficient food and die, leaving them unable to reproduce and pass the trait on to offspring.

D) A random mutation introduced the shorter, thicker beak into the population. However, those with thinner, longer beaks were better able to get nectar from the island's flowers. Those birds with the shorter, thicker beaks were unable to get enough food to survive.

E) A disease swept through the island killing many of the insects that were common on the island, leaving the birds who ate insects from the ground starving. The finches that had thicker beaks and could get food from tree bark were able to continue to survive and reproduce, increasing this trait in the population.

Dominic made the table below to organize his notes about mixtures. A 1-column table. The first column labeled properties of mixtures has entries has no set composition, must have more than one state of matter, must have more than one substance. What mistake did Dominic make? A. The title should read “Properties of Solutions” because some mixtures do not have all of the properties listed. B. There is a definite recipe to make each mixture, so the composition of a mixture is set. C. Although it is possible to have more than one state, it is also possible to have only one state. D. A single substance can be used to make a mixture if the substance is composed of more than one element.
