Evolution

According to the characteristics chart, which finch species primarily feeds on large seeds?

• Large Ground Finch

• Warbler Finch

• Small Ground Finch

• Cactus Finch

What type of beak does the Cactus Finch have?

• Crushing

• Probing

• Pecking

• Slicing

During the "Beaks of Finches" lab activity, what aspect was altered to simulate different environmental conditions on various islands?

• Type of beak

• Size of beak

• Type of seeds present

• Size of stomach container

How did the finches of the Galapagos Islands adapt after arriving from Ecuador?

• Quickly changed to fit the new environment of the islands

• Outcompeted all other bird species native to the islands

• Survived based on the adaptations they had to the new environment

• Mated with other bird species on the islands, resulting in birds better adapted to the new environment

As their environment slowly changes, organisms with certain traits are more likely to survive and produce offspring with those same traits. This statement describes:

• Cell division

• Genetic engineering

• Resource conservation

• Natural selection

What method should a forensic scientist use to compare the composition of pigments on a suspect's jeans to the pigments of plants at a crime scene?

• Restriction enzymes

• Genetic engineering

• Paper chromatography

• Receptor molecules

What characteristic could provide a species with a better chance of surviving a drastic environmental change?

• A) A small population size

• B) A highly diversified gene pool

• C) Specialized cells within the body

• D) Many individuals with the recessive trait

What are two sources of variations in organisms?

• Mitosis

• Mutations

• Cloning

• recombination

Why do studying fossils provide evidence for evolution?

• They take a long time to form

• They can show patterns of biological change over time

• They always contain complete DNA sequences

• They found in the same area are usually closely related to each other

Inherited trait that helps an organism survive is a(n) __________.

• Fossil
• Adaptation
• Ancestor
• Natural selection
