What is natural selection?

• A process where all individuals have an equal chance of survival.

• A method of breeding plants and animals for desired traits.

• The process by which individuals with favorable traits are more likely to survive and reproduce, leading to the gradual evolution of species.

• A theory that suggests species do not change over time.

What is an adaptation?

• A trait that enhances an organism's ability to survive and reproduce in its environment.

• A physical change that occurs in an organism over a single generation.

• A behavior that is learned by an organism to cope with its surroundings.

• A random mutation that has no effect on an organism's survival.

What is selective breeding?

• Selective breeding is the process of breeding plants or animals for specific traits, often used in agriculture and animal husbandry.

• Selective breeding is the random mating of plants or animals to increase genetic diversity.

What is the role of genetic material in inheritance?

• Genetic material determines the color of an organism's skin.

• Genetic material carries the information that controls inherited traits passed from parents to offspring.

• Genetic material is responsible for the organism's ability to move.

• Genetic material only affects physical traits, not behavioral traits.

What is the difference between asexual and sexual reproduction?

• Asexual reproduction involves two parents and results in genetic variation.

• Asexual reproduction involves a single parent producing genetically identical offspring, while sexual reproduction involves two parents and results in genetic variation.

• Sexual reproduction involves a single parent producing genetically identical offspring.

• Asexual reproduction results in genetic variation, while sexual reproduction does not.

What is the function of the nucleus?

• The nucleus is the control center of the cell, containing genetic material and regulating cellular activities.

• The nucleus is responsible for energy production in the cell.

• The nucleus helps in the synthesis of proteins.

• The nucleus is involved in the transport of materials within the cell.
