Define an Offspring
Product of reproduction; a new organism produced by one or more parents
100
Yellow beetle and green beetles live in the rainforest canopy. You would expect:
The green population of beetles will increase and the yellow population will decrease
100
What is a histogram?
A chart that tells which trait was distributed and the variation.
100
What process is labeled as "survival of the fittest"?
Natural Selection
100
Which of the following is NOT a trait that has evolved in Galápagos finches?
A. Beak size and shape
B. Ability to fly
C. Diet
B. Ability to fly
200
Define a Favorable Trait
A trait that is beneficial to an organism and will likely be chosen by natural selection
200
What is most likely to happen to moth populations in the picture shown?
Dark moths are easily seen by predators and hunted easily, over time the dark moths population will decreases.
200
Whether a trait is adaptive or not depends on the environment? (True or False)
True
200
What caused the newts to become poisonous?
Snakes (predator's) was added to the environment
200
True or false. Mutations are not random and can be chosen by people.
False. Mutations are random
300
Define Genetic Variation
Differences that exist within a population or the same species
300
In Natural Selection, What happens to the trait that was most common over many generations?
It becomes the adaptive trait and organisms will be more likely to survive.
300
Define Natural Selection
Process by which organisms with favorable traits are able to survive and reproduce better and over time become more common in the population
300
A species of fish evolves to have a thicker coat to survive in colder waters. This is an example of what?
Natural Selection
300
A group of fish have been observed to show changes in mouth structure over many generations. What is this change a result of? Explain.
Natural selection. Fish adapting to the food source for survival.
400
In an arctic environment, which would survive longer: red foxes or white foxes?
White foxes
400
What is an adaptative trait?
A TRAIT that helps an organism to survive and reproduce better in its environment
400
After traveling to the Galapagos Islands, Darwin noticed a lot of variation among beak sizes in Finches. This variation was a result of:
Developing different adaptations in order to survive on particular islands, specific to foods they eat.
400
Ancestors of the Galápagos finches who had large strong beaks were most likely adapted to eating?
What are seeds or hard shelled foods.
400
How does the environment play a role in natural selection?
It determines which traits are beneficial for survival.
500
What is a change in a gene that results in a new trait?
What is a mutation?
500
What is a change or difference in offspring called?
What is a variation?
500
Can an organism "CHOOSE" to evolve and change?
No, organisms CANNOT CHOOSE to change their genes or traits!
500
What role do mutations take during Natural Selection?
Mutations can help a species survive better in their environment and lead to adaptive traits. These traits can be passed down to offspring and over time the population changes.
500
What is a non-adaptive trait?
A trait that will make it less likely for an organism to survive.
