Benchmark 1 Study Set (22-23)

What word describes a trait that helps an organism survive in its environment?

• natural selection

• mutation

• camouflage

• adaptation

Which organisms are most likely to survive?

• the best adapted
• the fastest
• the strongest
• the most domesticated (tamed)

The trees these moths used to live on were white, but have been covered in soot from coal factories. Which moth will be more successful in this environment?

• Dark moth
• Light moth
• Both will be equally successful
• Neither will be successful

These moths are all the same species. The differences between their wings is an example of ________________

• Natural Selection
• Variation
• Homeostasis
• Extinction

When an organism of a species has an adaptation, it will compete for resources better, survive longer and pass that adaptation on to it's offspring. This process is called

• evolution by natural selection
• artificial selection
• inbreeding
• outbreeding

Evolution works by 

• individuals changing to suit their environment
• Individuals learned new traits and pass them on
• sudden change in the environment cause a species change 
• small changes pass down through many generations

Mutations are important because they bring about

• death of the organism in which they develop
• genetic variation needed for a population to evolve
• benefits for the individual, not for the population
• Hardey-Weinberg equilibrium within a population

Natural selection results in change in a population's _____________ traits over time.

• inherited

• acquired

Individuals undergo evolution.

• True

• False

The ability of an organism to survive and reproduce in its specific environment 

• diversity.
• evolution
• adaptation
•  fitness
