Adaptations and Survival in Organisms

The video tutorial explains adaptation as a genetic change aiding survival. It covers structural and behavioral adaptations, exaptation, and habitat-driven changes using examples like succulents and peppered moths. Speciation through isolation is discussed with marsupials as a case study. Co-adaptation and mimicry are illustrated with hummingbirds and king snakes. The video concludes with a quiz to reinforce learning.

What is an adaptation in the context of genetics?

• A type of mutation or change in an organism's genes

• A structural change in an organism's habitat

• A behavioral change in an organism

• A change in an organism's environment

Which of the following is an example of a structural adaptation?

• Birds flying south for the winter

• Succulents storing water in thick stems

• Gray whales migrating

• Hummingbirds collecting pollen

What is exaptation?

• A structural adaptation in plants

• A behavioral adaptation in animals

• A type of mimicry in organisms

• An adaptation developed for one purpose but used for another

How did the English peppered moth adapt to industrial pollution?

• By migrating to cleaner areas

• By changing its feeding habits

• By developing a darker color to blend in with polluted environments

• By becoming nocturnal

What is speciation?

• The adaptation of organisms to industrial pollution

• The development of new species through adaptations

• The mimicry of one species by another

• The process of organisms migrating to new habitats

What is co-adaptation?

• When organisms adapt to industrial pollution

• When organisms migrate together to new habitats

• When organisms adapt together, benefiting each other

• When one organism adapts to resemble another

Which of the following is an example of mimicry?

• A flower producing nutritious pollen

• A harmless snake resembling a deadly one

• A bird migrating to warmer climates

• A plant storing water in its leaves

Why are adaptations important for organisms?

• They help organisms find food

• They enable organisms to change color

• They allow organisms to migrate

• They help organisms survive in their environment

What prediction can be made about peppered moths as factories clean up their smoke?

• The number of light moths will increase

• The number of light and dark moths will stay the same

• The number of dark moths will increase

• The number of light moths will decrease

How does co-adaptation help organisms survive?

• By enabling them to migrate together

• By helping them share food sources

• By allowing them to change in ways that benefit both

• By enabling them to create new species
