Benchmark #3 review 2

What is a mutation?

• When animals have extra legs

• When a frog has 3 eyes

• When genes or DNA have been alterd or changed

• When RNA is upside down

Where are genes located?

• on the cell

• in the mitochondria

• on chromosomes

• on an organism

Where the better adapted organisms survive to pass traits along to offspring.

• Evolution
• Natural Selection
• Extinction
• Artifical Selection

What is the advantage of having different shaped beaks?

• To look different from other species.
• To be able to eat the food readily available in the environment.
• To protect itself against predators.
• To protect itself against prey.

Why are advantageous traits more likely to be passed onto offspring?

• Because they are more likely to survive and reproduce.
• Because they come from dominant alleles.
• Because they come from recessive alleles.
• Because the trait is an acquired phenotype.

Which of the following is NOT evidence of evolution?

• embryology

• biochemistry (DNA)

• acquired traits

• anatomy

When a farmer breeds two corn plants to produce the largest, sweetest corn on the cob, the farmer is using

• artificial selection

• natural selection

• acquired traits

• adaptations

Homologous structures

• are structures that are similar in related organisms that have a common ancestor

• do not exist in animals

• are structures that are similar in different organisms

• are structures that are exactly the same in organisms

A structure in a organisms that no longer functions

• chromologous structure

• analogous structure

• homologous structure

• vestigial structure

Analogous structures are

• anatomically similar with similar functions

• anatomically different with similar functions

• anatomically similar with different functions

• do not exist in animals
