Vocabulary
What would a 0% survival rate mean?
The species went extinct (died out)
What are the two locations where the team collected Arabidopsis plants?
Mediterranean locations and Scandinavian locations
How many answer choices do you select in question 2?
You pick the 3 best answer choices in #2
What does a 90% survival rate mean?
9 out of 10 plants lived
If an organism is "better suited" to its environment, does that mean it survives or it dies?
"better suited" = the organism has traits to help it survive and reproduce
What are the 2 different environments like where the seedlings were collected from? Include temperature or climate information.
“Mediterranean and Scandinavian plants have adapted to specific environments.” means...
The plants are more likely to survive in the environment where they are from
In which location did the plants from the Scandinavian environment have a higher survival rate?
The plants from the Scandinavian environment had a higher survival rate in the Scandinavian environment (73%) compared to the Mediterranean environment (62%)
If a species has a 60% survival rate in Location A and an 80% survival rate in Location B, which environment is it "adapted to?"
The species is adapted to location B because its survival rate is higher.
What do the field plot diagrams show about where the team replanted the seedlings?
They put 5 Mediterranean plants and 5 Scandinavian plants in the warm location, and 5 of each type in the cold location.
What would it look like if answer choice A for #2 was correct? ("Plants from the Mediterranean are better suited to survive in colder environments")
The seeds under "Source: Mediterranean" would have a high survival rate in the Scandinavian environment
What might kill the plants from the Mediterranean environment if they were replanted in the Scandinavian environment?
Being too cold
If a location is at a "high altitude" what does that mean?
It is on a mountain or otherwise elevated high above the sea level
If Doug's claim “Mediterranean seeds planted in the Scandinavian environment will become extinct over time." is true, what would that look like?
Seeds that came from the warm environment but planted in the cold environment will not survive
Choices C and F refer to high and low latitude. According to the 2nd paragraph on page 3, what latitudes (high or low) go with each location?
Mediterranean locations = low latitudes (closer to equator); Scandinavian locations = high latitudes (farther from equator)
Would the Mediterranean seeds have a high rate of survival or a low rate of survival in a cold Scandinavian environment?
Low rate of survival because they might not all have traits needed for survival in the cold location
Does an individual organism evolve by getting new traits?
No, a species evolves if certain traits are more favorable for reproduction.
What would it look like if the plants evolved a trait over time?
What did Doug predict would happen to the Scandinavian plants planted in a Scandinavian environment? What happened in the experiment?
He predicted that 100% would survive. Only 73% of the Scandinavian plants planted in the Scandinavian environment survived.
If a Scandinavian plant did actually survive the warm Mediterranean environment, would would that mean?
The plant managed to survive because it randomly inherited traits or had a mutation that gave it the ability to tolerate warmer temperatures.
