Which of the following explains what environmental and physical characteristics of the finch's led Darwin to develop his theory?
30
Darwin concluded that the beaks were different because the finches were not related species
on the different islands.
Darwin concluded that the beaks were different because they are acquired traits that developed based on the food source.
Darwin concluded that the beaks were different because the food source allowed for
survival of the trait that was best and passed on.
Darwin concluded that the beaks were different because they are attracting various predators that will eat them for energy.

Q.
The Green Ash tree is an important species for many organisms in American forests. They provide food and shelter for birds, squirrels, raccoons, and even frogs. Recently an invasive beetle called the emerald ash borer has been found and is having a profound impact on these trees. Below is a graph of the tree population in Wisconsin before and after the beetle was discovered there in 2017. Which statement best describes how this beetle is affecting genetic diversity in the Green Ash Trees?

A population of moths known as peppered moths (Biston betularia) lives in a birch forest in England. There are 2 phenotypic variations for color in the population, as seen in the picture: dark gray and light gray moths. The birch trees on which they live have a light colored paper-like bark. The peppered moth is preyed upon by insect-eating birds that hunt by sight. Which of the following is MOST likely true?

Q.
The medium ground finch is a species of bird found in the Galapagos Islands. It eats by cracking seeds open with their beaks to obtain the food inside. Finch beak size (depth) is controlled by the BMP4 gene, which produces a growth factor which results in larger size beaks. In 1977 the Galapagos Islands experienced an intense drought (no water), which severely reduced the population of small seeds. Which of the following statements BEST explains the trend in finch beak size during 1976 -1978 (see graphs).
