What is A gene?
200
What is most likely to happen to moth populations in the picture shown?
Dark moths--hunted easily, dark moths--population decreases.
200
Does natural selection take a long time or a short time?
What is a Loooooooooooooooooooooooooooooooooooooong time?
200
Due to pollution, a pond becomes darker over time. Which trait variation became more common?
What is dark fish?
200
Bees are attracted to bright colors like red and pink. What would happen to a population of roses that had red, pink, and white flowers?
The white flowers will eventually die because they won't be getting pollinated.
300
What is a change in a gene that results in a new trait?
What is a mutation?
300
What is the variety of alleles (R or r) that exist and are expressed or seen in a population?
(Every population has some differences which cause different traits.) What is this called?
What is Genetic Variation?
300
What is how well an organism is suited for its environment?
It has adaptations that allow it to thrive where it lives!
What is "fitness"?
300
What word describes a TRAIT that HELPS AN ORGANISM SURVIVE in its environment?
What is ADAPTATION?
300
A pumpkin farmer want to grow the largest pumpkin possible. He mates his largest pumpkin with his second largest pumpkin and plants the seeds. The next year he mates the pumpkins from these seeds with his largest pumpkins. Eventually, he starts getting very large pumpkins. Is this natural selection or artificial selection?
Artificial selection
400
A TRAIT that helps an organism to survive and reproduce in its environment
What is Adaptation?
400
What would happen if the environment changes drastically and no organisms have fitting adaptations?
What is a species could go extinct?
400
What is it called when organisms of the same species live in a particular geographic area at the same time?
What is POPULATION?
400
Can an organism "CHOOSE" to evolve and change?
No, organisms CANNOT CHOOSE to change their genes or traits!
400
A population of hummingbirds have long beaks and short beaks. The flowers the hummingbirds usually eat from have died and now the hummingbirds need to eat from smaller flowers. How will the population of hummingbirds change?
The hummingbirds with long beaks will die and there will be more hummingbirds with short beaks.
500
Survival of the fittest - the organisms that fit the best with their environment survive and reproduce and those that don't fit in die
In other words... better adapted organisms survive to pass traits along to their offspring.
What is Natural Selection?
500
TRUE or FALSE: Natural selection will still occur if each individual has the same exact traits.
What is false?
In order for natural selection to take place, there must be genetic variation.
500
How do you "win" at natural selection?
What is "SURVIVE" and "REPRODUCE?"
500
Which term means a group of similar organisms that can reproduce fertile offspring?
What is species?

In a group of poison ivy, some plants do not produce the chemical that causes itching and is eaten by animals. What will happen to this population?
The poison ivy without the chemical will die.
