Explain how genetic diversity influences the process of natural selection.
|
Over time, the process of natural selection leads to:
no change in the population's adaptation to the environment
populations becoming more adapted to their environment
random changes in the population's adaptation to the environment
populations becoming less adapted to their environment
|
Which of the following statements about genetic diversity is FALSE?
it is the total number of different alleles in a population
it leads to variation in observable traits
it influences natural selection
it is always caused by beneficial mutations
|
Which of the following is NOT a step in the process of natural selection?
genetic variation emerges within a population due to random mutations
advantageous alleles are passed down to offspring
individuals with advantageous traits are more likely to reproduce
organisms actively adapt to their environment
|
Genetic diversity influences natural selection because:
organisms with advantageous traits are less likely to survive and reproduce
it leads to less variation in observable traits
different combinations of alleles result in different proteins
all of the above
|
What describes an organism's ability to survive and reproduce?
adaptation
fitness
variation
mutation
|
Which of the following is NOT a selection pressure?
predation
climate change
competition for resources
genetic drift
|
Which of the following is NOT a consequence of pesticide resistance in insects?
environmental damage
crop losses
increased pesticide use
decreased pest population
|
When antibiotics are used, what happens to the bacteria population?
bacteria stop reproducing
all bacteria die off
only resistant bacteria survive
bacteria become more susceptible to antibiotics
|
How do resistant bacteria pass on their resistance to offspring?
by passing on specific alleles
by increasing mutation rates
by actively teaching their offspring
by creating a protective environment
|
The development of pesticide resistance in insects typically occurs through:
genetic drift
gene flow
artificial selection
natural selection
|
Which of the following is NOT a typical consequence of antibiotic resistance in bacteria?
complicated treatment options
increased healthcare costs
raised mortality rates in humans
increased prevalence of viral diseases
