What is an adaptation in the context of biology?

• A variation that makes an organism better suited to its environment

• A random change in an organism's appearance

• A mutation that always leads to a disadvantage

• A temporary change in behavior

In the study by Rosemary and Peter Grant, what trait helped some finches survive during a drought?

• Faster flying speed

• Brighter feathers

• Larger wingspan

• Slightly larger beaks

How are advantageous traits passed on to future generations?

• By learning from other species

• Through random chance

• By being encoded in the organism's genetic material

• Through environmental changes

What is the key principle of Darwin's theory of evolution?

• Natural selection

• Genetic drift

• Artificial selection

• Random mutation

What does the phrase 'survival of the fittest' imply?

• Survival is based on luck

• Only the strongest organisms survive

• Organisms with beneficial adaptations are more likely to survive and reproduce

• All organisms have an equal chance of survival
