Darwin visited the Galapagos Islands several times. During his trips, he observed some differences in the finches living on each of the islands. He noted that the finches had many traits in common; however, each had a different beak. Some beaks were short, some long. Some beaks looked straight, while others curved. Darwin believed that each species of finch was related but had developed some special beak adaptations. He suggested that the finches had developed these adaptations because there were different food sources on each island. The curved-beaked finches ate berries. The straight-beaked finches burrowed for worms. The short-beaked finches ate only seeds. Each beak was well suited for the specific food source.

What is the main idea of this paragraph?

A. Darwin likes finches.
B. Finches are picky eaters.
C. The Galapagos Islands are a nice place to visit.
D. Darwin believed the shape of the finch's beak was related to the food it ate.

Question 3 (Multiple Choice, Worth 2 points)

A genotype describes

A. what an individual looks like.
B. how an individual will pass on traits.
C. how long an individual will live.
D. the genetic makeup of an individual.

Answer :

Final answer:

Correct option is Darwin believed the shape of the finch's beak was related to the food it ate. Darwin observed that finches in the Galapagos Islands had different beak shapes suited to their food sources, suggesting adaptive evolution from a common ancestor. Correct option is the genetic make up of an individual. A genotype refers to an individual's genetic makeup that dictates hereditary traits.

Explanation:

The main idea of the paragraph is that Charles Darwin believed the shape of the finch's beak was directly related to the type of food it ate, which he observed during his visits to the Galapagos Islands. This adaptation is a key aspect of Darwin's theory of natural selection, where the finches' beaks evolved over time to best suit their respective environments and available resources. Darwin noted that finches from the mainland had a certain beak shape, but each species in the Galapagos had developed unique beak shapes that helped them acquire a specific type of food, thus suggesting an evolutionary progression from a common ancestor.

A genotype describes the genetic makeup of an individual, which includes all the genes that contribute to that individual's hereditary traits. Unlike a phenotype, which is the observable characteristics, a genotype refers to the inherited instructions an individual carries within their genetic code that determine how those traits are expressed.

First: Darwin believed the shape of the finches beak was directly related to its food source.

Second: A genotype decides the genetic makeup of an individual, (green eyes, blue eyes, brown eyes, etc.)
