B. A method used by scientists to create new species.
C. The intentional breeding of plants and animals.
D. A theory that explains how life began on Earth.
Which of the following is an example of natural selection?
A. A farmer selecting the best crops to plant each season.
B. Peppered moths becoming darker in polluted areas.
C. A pet dog learning new tricks.
D. Humans developing larger brains over generations.
What role do mutations play in natural selection?
A. They are harmful and always reduce an organism's chances of survival.
B. They are random changes that can introduce new traits into a population.
C. They are planned changes made by organisms to adapt quickly.
D. They have no effect on the process of evolution.
Which of the following best describes "survival of the fittest"?
A. Only the strongest organisms survive.
B. The concept that all organisms compete to stay alive, regardless of their traits.
C. Organisms that are best adapted to their environment are more likely to survive and reproduce.
D. Only the oldest individuals in a species can reproduce.
How does natural selection lead to evolution?
A. It confirms that species do not change over time.
B. It introduces new species by forcing adaptations through environmental pressure.
C. It allows beneficial traits to become more common in a population over generations.
D. It decreases the population of a species.
Which factor is NOT a component of natural selection?
A. Variation in traits among individuals.
B. Overproduction of offspring.
C. Environmental pressures.
D. Symbiosis between different species.
In a given species, why might some individuals have advantages over others?
A. They possess advantageous traits that allow better survival in their environment.
B. They are always the largest individuals in the population.
C. They live longer than others, regardless of their traits.
D. They are the first born in their group.
Which scenario best illustrates environmental pressure in natural selection?
A. Animals choosing mates based on appearance.
B. A sudden change in climate that affects food availability.
C. Human interference such as habitat destruction.
D. All of these options.
What happens to traits that provide a survival advantage in a population?
A. They decrease in frequency over time.
B. They remain constant regardless of the environment.
C. They are more likely to be passed on to future generations.
D. They become irrelevant as species evolve.
What is the outcome of natural selection over many generations?
A. The creation of completely new species every time.
B. A stable population with no changes over time.
C. Adaptations that increase the fitness of a population.
D. A population that becomes extinct due to constant change.
