All the answers are true

Behavioral Adapatation - Interbreeding between plants and animals of a different species - A characteristic that an organism can pass on to its offspring through its genes - Adapation which allows an organism to blend in to its environment - An adaptation that has to do with how an organism acts that helps it survive

An adaptation that has to do with how an organism acts that helps it survive

The domestication of animals shows that animals can undergo dramatic changes over a relativley short number of generations. Animals have been selectively bred for centuries, leading to the wide range of animals today. - Artificial Selection - Domestic Selection - Human Influenced Selection - Natural Selection

Artificial Selection

Which of the following is not caused by living things to drive extinction? - Climate Change - A new competitor - A new disease - A new predator

Climate Change

Finches on the Galapagos Island had different beaks in order to help them do what? - Collect food sources - Fight off Predators - Compete with rivals - Build Nests

Collect food sources

An Ancestor shared by more than one species. - Fossil - Ancestor - Common Ancestor - Grandparent

Common Ancestor

If an _________________ change is too fast, or too larger, then members of the species will not be able to adjust to it. - Geological - Human Created - Environmental - Natural

Environmental

More and more bacteria are becoming resistant to antibiotics. This is an example of which of the following? - Chance - Competition - Evolution by Natural Selection - Predation

Evolution by Natural Selection

The fossil record shows gradual changes in preserved specimens of the same specimens of the same species over time. this provides evidence of __________ change over millions of years, showing how species have changed over time. - Evolutionary - Adaptaitonary - Natural - Comedic

Evolutionary

Species that cannot adapt to enviornmental changes become... - New species - extinct - adapted - Better suited to their environment

Extinct

True or False: An individual organism can adapt to its surroundings.

False

True or False: Most species that have lived on earth are living today.

False

All of the Genetic differences in a population. - Generations - Adaptation - Genetic variation - Population

Genetic Variation

What was the name of Charles Darwins ship that took him to the Galapagos Islands? - HMS Bernard - HMS Eagle - HMS Beagle - HMS Batman

HMS Beagle

Characteristics that can be passed on from parents to offspring are called - genotype - Heritable - physical features - inheritance

Heritable

Which of the following is nout used as evidence for the theory of evolution? - Hydrogeology - Genetics - Molecular biology - Developmental biology

Hydrogeology

The outcome to a speciation event where two groups of the same species become isolated from each other and over time the two populations become so different from each other where they are unable to __________. - find food - Adapt - Interbreed - Understand vocalization

Interbreed

What traits do a tiger and a salamander both share? - Amniotic membrane, lungs, jaws - Lungs, Jaws - None - Hair, Amniotic Membrane, Lungs, Jaws

Lungs, jaws

A population of Bison were split into two groups by a riverbed that formed after a massive flood. After many generations, the river changes course allowing the two groups to mix together. Two Seperate Species if.... - The Bison interbreed, but their offspring are shorter than either of the parents - The groups mate and offspring are produced, but the offspring are sterile - Members of the two different groups refuse to interbreed - One group has twice as many bison with longer fur

Members of the two different groups refuse to interbreed

A Mutation occurs that is beneficial to an organism. That organism survives and passes this trait to its offspring. Eventually the trait is widespread in the population. This is an example of...... - Natural Selection - Genetic Variation - Non-inheritable variation - Artifical Selection

Natural Selection

Charles Darwin propsed that evolution took place through the process of _____________ __________________ - Adaptation - Artificial Selection - Change over time - Natural Selection

Natural Selection

Bacteria that are not responsive to treatments with drugs. These bacteria are often tolerant of the drug and do not die from it. - Persistent - Immortal - Encapsulated - Resistant

Resistant

Which Occurence represents an example of evolution? - Exposure to radiation reduces the rate of mutation in leaf cells. - A mutation in a liver cell causes a person to produce an enzyme that is less efficient - Some antibiotics are almost useless, because pathogens have developed a resistance to these antibiotics. - Cells in a zygote eventually change into bone cells or skin cells

Some antibiotics are almost useless, because pathogens have developed a resistance to these antibiotics.

Over time, Natural selection may cause a population to become so differnet that it becomes a completely new species that is no longer able to interbreed. this Process is called.. - Natural Selection - Evolution - Speciation - Adaptation

Speciation

Two important concepts in the process of __________ are isolation and natural selection. - Adaptation - Evolution - Mutation - Speciation

Speciation

Overproduction - Strategy in which organisms make more offspring than will actually survive - Genetic Information that can be used as evidence of evolution between organisms - Selection by humans for breeding of useful traits from the natural variation among different organism - Difference among member of a species

Strategy in which organisms make more offspring than will actually survive

According to Natural Selection, why are some individuals more likely to survive and reproduce? - They are already better adapted to exist in the environment - They tend to produce fewer offspring than others - They can pass on traits acquired during their lifetime - They can't pass on traits acquired during their lifetime

They are already better adapted to exist in the environment

True or False: Extinction can be caused by changes in the environment that a species lives in.

True

Darwin discovered that individuals organisms within a species showed ___________ in their characteristics - Relatedness - variation - Physical Advantages - Similarities

Variation

Individuals in a population of a species show differences in the characteristics. This is called ______________.

Variation

Mutations are important because they bring about - Death of the organism in which they develop - Benefits for the individual, not for the population - genetic variation needed for a population to evolve - Hardey-Weinberg equilibrium within a population

without genetic variation... - populations could not adapt to environments - populations would be healthier - every species would go extinct - only the most fit offspring would survive
