Genetic variation, as well as changes in the environment, cause characteristics of organisms to change over time. This process of natural selection leads to the evolution of new species.
What is artificial classification?
Classification based on the evolutionary relationship between organisms
Classification based on the observable characteristics of organisms
Classification based on the genotype of the organism
Which theory describes how new species evolve?
Which individuals are most likely to survive to reproduce?
Individuals that are poorly suited to their environment
Individuals that are best suited to their environment
Individuals that have no immunity to new diseases
What is the smallest division of the classification system?
Which are the correct five kingdoms?
Animals, plants, fungi, protists and prokaryotes
Animals, plants, fungi, protists and archaea
Animals, plants, fungi, protists and eukaryotes
Which are the correct five classes of vertebrate?
Mammals, birds, amphibians, fish and reptiles
Mammals, birds, amphibians, fish and bacteria
Mammals, birds, amphibians, fish and insects
How does the development of an antibiotic resistant population start?
A random mutation causes a bacterial cell to become resistant to the antibiotic
The presence of the antibiotic makes a bacterial cell become resistant to it.
A bacterial cell chooses to change itself to become resistant to the antibiotic.
What is the definition of variation?
The genes an organism has
The phenotype an organism has
The differences in characteristics between organisms
Explain why a brown rabbit that is placed in the snowy Arctic does not survive.
It is camouflaged so is eaten by predators
It is not camouflaged so is eaten by predators
It is well suited to the environment
A frog gets a random mutation in the gene that controls tongue length so its tongue becomes very long and it can catch more flies. What would happen to the number of frogs with this gene?
Stay the same
