Total questions: 21

Over time, animals may change behavior or physical appearance in response to changes in the environment. What is this called?
resistance
genetic change
adaptation
genetic variation
Many insects can adapt very quickly to insecticides because :
the insects' genetic structure is stable
the insects' generation time is short
the insects' form separate species
they form a hard skeleton
What do we call the process by which populations change over time?
evolution
speciation
selective breeding
adaptation
Scientists compare organisms' DNA to support the theory that all species share a common:
environment
separation
population
ancestor
A characterstic that can be passed from parent to offspring through genes is called:
resistance
sediment
trait
genetic change
What process often begins by a portion of a population becoming physically or geographically separated?
speciation
selective breeding
genetic change
resistance
What evidence of natural selection is available today that was not available to Darwin?
There is great variation among organisms
organisms inherit traits
differences in genes create variation
humans can breed organisms for specific traits
A turtle will lay 100 eggs, knowing only a few will survive. This is called:
division
genetic change
speciation
overproduction
