Natural Selection

What is the difference between evolution and natural selection?

• Evolution is the change in the genetic composition of a population over time, while natural selection is a mechanism that drives evolution.

• Natural selection is the process by which organisms adapt to their environment, while evolution is the survival of the fittest.

• Evolution refers to the physical changes in an organism, while natural selection is about the reproduction of the strongest individuals.

• Natural selection is a theory that contradicts evolution, suggesting that species do not change over time.

What is the significance of genetic diversity?

• It allows for faster reproduction rates in a population.

• It is crucial for the survival and adaptability of a population, allowing it to respond to environmental changes.

• It reduces the chances of mutation in genes.

• It increases the likelihood of inbreeding within a population.

What is Natural Selection?

• Natural Selection is the process where organisms that are better adapted to their environment survive and reproduce, passing on their advantageous traits to their offspring.

• Natural Selection is the method by which all organisms are created equally and thrive in their environments.

• Natural Selection is the phenomenon where weaker organisms dominate the ecosystem.

• Natural Selection is the process of random genetic mutations that have no impact on survival.

What is a selective pressure?

• A type of genetic mutation that occurs in a population.

• An environmental factor that influences which individuals survive and reproduce.

• A method of breeding organisms for desired traits.

• A process that leads to the extinction of a species.

How did the frequency of light-colored and dark-colored peppered moths change during the Industrial Revolution?

• Light-colored moths became more common due to pollution.

• Dark-colored moths became more common as they were harder to spot on dark trees.

• The frequency of both light and dark moths remained the same.

• Light-colored moths adapted to become darker over time.

What is an adaptation?

• A trait that helps an organism survive and thrive in its environment.

• A type of food that organisms consume.

• A method of reproduction in plants.

• A seasonal change in an organism's behavior.

What is Artificial Selection?

• A process where nature selects the best traits for survival.

• A method of breeding plants and animals for specific traits by humans.

• A technique used to enhance genetic diversity in species.

• A natural phenomenon that occurs without human intervention.

What is the difference between Natural Selection and Artificial Selection?

• Natural Selection is driven by human choices, while Artificial Selection occurs naturally based on environmental pressures.

• Natural Selection occurs naturally based on environmental pressures, while Artificial Selection is driven by human choices.

• Natural Selection and Artificial Selection are the same processes with no differences.

• Natural Selection is a process that only occurs in plants, while Artificial Selection occurs in animals.

What is the role of environmental changes in natural selection?

• Environmental changes can create new selective pressures, leading to changes in which traits are favored in a population.

• Environmental changes have no impact on natural selection.

• Environmental changes only affect the physical characteristics of organisms, not their traits.

• Environmental changes eliminate the need for adaptation in species.

What is camouflage?

• A method of communication among animals.

• A trait that allows an organism to blend in with its environment, helping it avoid detection by predators.

• A type of habitat where animals live.

• A strategy used by animals to attract mates.
