5) Darwin concluded that organisms on the Galápagos Islands
A
had changed over time
B
had remained the same
C
had no variations
D
were the result of selective breeding
6) How does Natural Selection lead to evolution?
A
Helpful variations accumulate among surviving members of the species.
B
Environmental changes favor weaker members of the species.
C
Stronger offspring kill weaker members of the species.
D
Overproduction only feeds the strong of the species.
7) What did Darwin infer from his observations of organisms in South America and the Galápagos Islands?
A
A small number of different plant and animal species had come to the mainland from the Galápagos Islands.
B
A small number of different plant and animal species had come to the Galápagos Islands from the mainland.
C
The organisms on the Galápagos Islands were completely unrelated to mainland organisms.
8) What did Darwin observe about finches in the Galápagos Islands?
A
They had identical phenotypes in all locations.
B
Their beaks were adaptations related to the foods the finches ate.
C
Their feathers were adapted to match their environment.
D
They had identical genotypes in all locations.
9) What do dichotomous keys use to help identify organisms?
A
Paired statements that describe physical characteristics of organisms
B
Photographs of a species that show physical variations of individuals
C
Photographs of a species that show physiological adaptations of individuals
D
Paired statements that describe behavioral adaptations of organisms
10) Which type of adaptation helps organisms survive in their environments?

Increases chances to meet possible mates
B
Avoids predators
C
Reduces need for food when it is scarce
D
Finds a place with a lot of food
13) How did Darwin explain the variety of finch beaks that he observed on the Galápagos Islands?
A
All finches came from a common species, and their beaks became adapted to the different foods they ate.
B
All finches came from different species, and their beaks developed differently due to selective breeding.
C
All finches came from a common species, and their beaks developed differently due to selective breeding.
D
All finches came from different species, and their beaks became adapted to the different foods they ate.
14) What is an adaptation?
A
The ability of a species to change over many generations
B
A trait that increases an organism's ability to survive and reproduce
C
The ability of a species to adapt to environmental changes
D
A trait that increases an organism's ability to grow and obtain food

B
Circadian rhythms enable certain animals to be active at night so that they do not encounter predators who are active during
C
All of the above.
