Natural Selection Review 2024

This makes an organism more suited to its environment

• species

• lifespan

• adaptation

• mutation

Where the better adapted organisms survive to pass traits along to offspring.

• Evolution

• Natural Selection

• Extinction

• Artifical Selection

Which organisms are most likely to survive?

• the best adapted

• the fastest

• the strongest

• the most domesticated (tamed)

Why is the mouse population changing over time?

• The light mice can reproduce more successfully than the dark mice

• The hawks eat more dark mice than light mice because the dark mice taste better

• The hawks eat more light mice than dark mice because they can see the light mice more easily

• The hawks eat more dark mice than light mice because they can see the dark mice more easily

These moths are all the same species. The differences between their wings is an example of ________________

• Natural Selection

• Variation

• Homeostasis

• Extinction

Mutations are a change in what?

• DNA

• tRNA

• protein

• rRNA

Why do frogs and other organism reproduce so many eggs or offspring?

• so that their babies can have friends to play with
• the more offspring the more likely the offspring will survive
• the more offspring the less likely offspring will survive 
• the more offspring the less competition

Do organisms "decide" to evolve and change?

• Yes, they know they need to change to survive 
• No, they change because of natural selection

Why is competition important for natural selection?

• It shows which variations are more successful, allowing the organisms with those variations to survive.

• It causes organisms, regardless of which traits they have, to die out, reducing the population size.

• It causes organisms to get stronger due to having to outcompete other species.

• Competition is not important for natural selection.

Dogs such as Chihuahuas are examples of....

• Artificial Selection 
• Natural Selection 
• Mutations
