Multiple Choice

What is the significance of variations for natural selection?

• Variation needs to exist for nature to select for or against certain traits

• Variations reduce the diversity for natural selection

• Variations are caused from natural selection

• Variations cause gene flow

Match

Match the terms with their definition:

• The movement of genes from one population to another

• All of the available alleles/genes in a population

• The process of the most fit surviving and reproducing

• The change in a population's gene pool/allele frequency over time

Gene Flow

Gene Pool

Multiple Choice

Natural selection affects the allele frequency in a population. What type of selection would lead to both extreme phenotypes being selected for?

• Disruptive

• Directional

• Stabilizing

Multiple Choice

What leads to biological resistance?

• A mutation for resistance is selected for by the chemical/drug, by removing those without resistance

• The species notices the drug/chemical and decides to mutate to become resistant

• The chemical/drug directly causes a mutation for resistance to develop by mutating the DNA

Multiple Choice

Most likely to lead to speciation:

• Gene Flow between populations

• Isolation due to barriers, timing, or rituals

Multiple Choice

What explains the reason for both whales and sharks having fins, even though they are not closely related?

• Convergent Evolution

• Divergent Evolution

• Gene Flow

• Genetic Drift

Match

Match the following terms with their definitions

• Movement of genes between populations

• Random chance event that reduces genetic diversity

• A type of drift from a natural disaster

• A type of drift where a small group colonizes an area

• Survival of the fittest

Gene Flow

Genetic Drift

Bottleneck Effect

Founder Effect

Natural Selection

• Gene Flow

• Genetic Drift

• Bottleneck Effect

• Founder Effect

• Natural Selection

Match

Match the following

• Remains of dead organisms, incomplete records

• A structure that lost its original purpose, but still present in the species

• Similar structure, different function

• Different structure, similar function

• Similarities in early stages allow for comparing of traits

Fossils

Vestigial Structure

Homologous Structure

Analogous Structure

Embryology

• Fossils

Multiple Choice

What does the biochemical evidence suggest is the most closely related organism to the human?

• Rhesus Monkey

• Dog

• Bird

• Fish

Multiple Choice

What do things like whale fossils help us see?

• Whales share a common ancestor with other ocean creatures

• There was a gradual change over time that led to the "whale"

• Whales didn't have any ancestors on land

• Whales and all of their ancestors have always lived in the water
