Question 22
22.
Which theory suggests traits acquired during life can be inherited?
Natural selection by Darwin.
Lamarck's theory of use and disuse.
Mutation theory of evolution.
Genetic drift theory.
Question 23
23.
Darwin's theory primarily explains change through?
Uniform changes across all species.
Natural selection changing allele frequencies.
Acquired traits based on use.
Environmental influence on conscious adaptation.
Question 24
24.
What is the founder effect in population genetics?
A gradual change of the climate affecting all.
A natural disaster killing many individuals.
A process of large populations spreading.
A change in allele frequency due to a small population's genes.
Question 25
25.
How does the bottleneck effect influence genetic diversity?
It has no impact on genetic diversity.
It increases variation through more breeding.
It reduces genetic variation by limiting population size.
It only affects phenotypes, not genotypes.
Question 26
26.
Which scenario exemplifies the founder effect?
A population spreading across a continent.
A few individuals colonizing a new island.
A flood killing most of a population.
A mutation arising in a large group.
Question 27
27.
Which best describes a consequence of the bottleneck effect?
Loss of genetic variation within a population.
Increased competition among individuals in the group.
Creation of new alleles through mutation.
Improved adaptability to environmental changes.
Question 28
28.
How do super germs survive antibiotic treatment?
They exist only in hospital settings.
They become harmful after contact with antibiotics.
They possess mutations that confer resistance.
They are always found in healthy individuals.
Question 29
29.
What can promote the formation of antibiotic-resistant bacteria?
Taking herbal remedies alongside antibiotics.
Eating yogurt after antibiotics is harmful.
Ignoring prescribed antibiotic treatment duration.
Drinking water after taking antibiotics only.
Question 30
30.
Why is it hard to treat infections caused by super germs?
They are smaller than regular bacteria.
They only infect the elderly population.
They grow slower than normal bacteria.
They resist multiple antibiotics commonly used today.
Question 31
31.
How has the age of the Earth affected biodiversity?
Earth's age has no effect on biodiversity.
Species evolved randomly over time.
Biodiversity decreases with age of Earth.
More time allows for more species to evolve.
Question 32
32.
What role does extinction play in increasing biodiversity?
Extinction has no impact on evolution.
Extinction always decreases biodiversity.
Extinction leads to genetic uniformity.
Extinction opens niches for new species to evolve.
Question 33
33.
What does the term 'adaptive radiation' refer to?
Species adapt only to immediate environments.
Rapid evolution of diverse species from a common ancestor.
All species evolve at the same rate.
Adaptive traits appear randomly without evolution.

Question 1
1.
What is speciation?
Random genetic mutations occur.
Process of populations evolving into distinct species.
Change in one species only.
Evolution of similar species.
Increase in population size.
Question 2
2.
What happens to gene pools during speciation?
They gradually become different and separate.
They always increase in size.
They only change due to disease.
They remain unchanged indefinitely.
They become identical over time.
Question 3
3.
At what point are two groups considered different species?
When they live in different habitats.
When they can no longer reproduce with each other.
When they look different physically.
When they eat different foods.
When they have different predators.
Question 5
5.
What type of evolution did the iguanas undergo?
Adaptive radiation resulting in different species.

Convergent evolution into similar forms.
Artificial selection by humans.
Question 6
6.
What is extinction?
Elimination of a species
Natural selection process
Change in habitat only
Increase in species population
Question 7
7.
What is mass extinction?
Loss of habitat gradually
Natural selection over time
Low species reproduction rates
Sudden loss of many species
Question 8
8.
What can lead to gradual extinction?
Changes in the environment
Global warming only
Meteor impacts
Immediate climate shifts
Question 9
9.
What is gradualism in evolution?
Slow, constant changes over time.
Rapid changes in species
No change in species over time
Sudden extinction of species
Question 10
10.
What is a key factor in gradualism?
One-time genetic shifts in species
Immediate changes in ecosystems
Mass extinction events
Time allows for small changes to accumulate.
Question 11
11.
What does gradualism take to produce new species?
Long periods of time and small changes.
External impacts only
Instantaneous changes
Single major mutations
Question 12
12.
What does punctuated equilibrium describe?

13.
What happens during bursts in punctuated equilibrium?
Changes happen slowly
No changes occur
Species disappear completely
Species go extinct
Rapid species diversification
Question 14
14.
What is divergent evolution often caused by?
New environments for species
Similar environments for species
Separate populations moving closer
Mutation in a single species
Question 15
15.
How does divergent evolution affect species appearance?

They become increasingly different
They become identical to each other
They become smaller in size
Question 16
16.
Why do species evolve differently in divergent evolution?
They don't share common ancestors
They all migrate to the same area
They are genetically engineered
Due to environmental changes
Question 17
17.
What is convergent evolution?
Animals become similar due to genetic mutation.
Related species evolve different traits.
