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.
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.
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.
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.
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.
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.
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.
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.
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.
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.
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.
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 34
34.
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.
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.
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.
What is speciation?
The formation of new species over time.
The mixing of species.
The extinction of a species.
The migration of animals.
What type of evolution did the iguanas undergo?
Adaptive radiation resulting in different species.
Gradual extinction of old forms.
Convergent evolution into similar forms.
Artificial selection by humans.
What is extinction?
Elimination of a species
Natural selection process
Change in habitat only
Increase in species population
What is mass extinction?
Loss of habitat gradually
Natural selection over time
Low species reproduction rates
Sudden loss of many species
What can lead to gradual extinction?
Changes in the environment
Global warming only
Meteor impacts
Immediate climate shifts
What is gradualism in evolution?
Slow, constant changes over time.
Rapid changes in species
No change in species over time
Sudden extinction of species
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.
What does gradualism take to produce new species?
Long periods of time and small changes.
External impacts only
Instantaneous changes
Single major mutations
What does punctuated equilibrium describe?
Only extinction events
Bursts of change with stability periods
No changes in species species
Constant gradual change
Overall species decline
What happens during bursts in punctuated equilibrium?
Changes happen slowly
No changes occur
Species disappear completely
Species go extinct
Rapid species diversification
What is divergent evolution often caused by?
New environments for species
Similar environments for species
Separate populations moving closer
Mutation in a single species
How does divergent evolution affect species appearance?
They stay exactly the same
They become increasingly different
They become identical to each other
They become smaller in size
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
What is convergent evolution?
Animals become similar due to genetic mutation.
Related species evolve different traits.
All species in one area evolve the same traits.
Unrelated species evolve similar traits due to environment.
Which of these is an example of convergent evolution?
Dogs and cats living in the same home.
Frogs and fish living in water.
Eagles and owls hunting at night.
Sharks and dolphins swimming in the ocean.
Why do unrelated species evolve similar characteristics?
They share the same diet.
They live in the same geographical area.
They live in similar environments.
They have a common ancestor.
What is coevolution?
Species becoming extinct together.
Species evolving in isolation.
Species adapting individually.
Species evolving together.
Why do species coevolve?
To compete for resources.
To avoid extinction together.
To dominate each other's habitats.
To adapt to each other's changes.
Which feature is unique to mammals in the chart?
Amniotic egg
Bony skeleton
Hair
Four limbs
