Natural selection
True or false?
Species can evolve in a single generation.
True or false?
Organisms with favorable traits are more likely to survive and reproduce.
True or false?
Organisms of the same species can vary in internal or external traits.
Complete the sentence.
A populationrefers to all the members of one specific species living together in a particular habitat.
Which skin color will be the most favorable trait for frogs living on a muddy riverbank?
red
brown
green
blue
Changes that appear in genetic material are:
mutations
adaptations
transformations
variations
A process in which humans choose what traits they want other organisms to have is called:
genetic drift
artificial selection
spontaneous mutation
natural selection
On which archipelago did Charles Darwin study organisms?
Azores
Galápagos
Midway
Faroe
What scientific idea is Charles Darwin most famous for?
idea of the DNA structure
theory of relativity
evolution by natural selection
laws of genetics and inheritance
evolution by natural selection
Match the steps of natural selection (V.I.S.T.A.) with their descriptions.
Variation
Differences between individuals of the same species, often due to genetic mutations.
Match the steps of natural selection (V.I.S.T.A.) with their descriptions.
Inheritance
The process by which genetic information (DNA) is passed from parent to child.
Match the steps of natural selection (V.I.S.T.A.) with their descriptions.
Selection
Organisms with helpful traits are more likely to survive and reproduce in an environment with limited resources.
Match the steps of natural selection (V.I.S.T.A.) with their descriptions.
Time
Traits become more common in a population over many generations, causing the population to evolve.
Match the steps of natural selection (V.I.S.T.A.) with their descriptions.
Adaptation
The result of natural selection where a population becomes better suited to its environment.
A segment of DNA that codes for a specific trait is called a:
gene
To call similar organisms a species, they must be able to:
protect their territory
interbreed and produce fertile offspring
have identical DNA sequences
look exactly the same
interbreed and produce fertile offspring
True or false?
Every species tends to produce more offspring than can reach maturity.
True or false?
Viruses are living organisms.
True or false?
Only plants can be subject to artificial selection.
When organisms reproduce, they pass to their offspring:
their BMI
their RNA
their DNA
their ATP
