What are the two ways to describe a population?

number of individuals who have the trait

This histogram shows Thornpalm water storage at generation 1 and generation 10. Which population had more thormpalms with high water storage?

Generation 10 has more with high water storage.

Both generations have the same number with high water storage.

Generation 1 has more with high water storage.

This histograms do not show which had more with high water storage.

This histogram shows an Ostrilope population at generation 1 and at generation 20. Which generation has greater variation in the fur distribution?

Generation 1 has greater variation in fur amount.

It is not possible to tell which generation has greater variation.

Generation 20 has greater variation in fur amount.

Both generations have the same amount of variation in fur amount.

The ostrilope population was measured after 20 generations when there was a change in the surface color to yellow. What is a true statement about these populations?

At generation 20 there were more ostrilopes with yellow fur.

At generation 1 there were more ostrilopes with yellow fur.

At generation 20 there were more ostrilopes than at generation.

At generation 20 there were more ostriplopes with blue fur.

Over many generations, what happens to the individuals that have the adaptive trait?

They become more common in the population.

They become less common in the population.

They adapt to their environment.

They become the predator in the environment.

Over many generations what happens to the individuals in a population that have the non-adaptive trait?

They become less common in the population.

They become more common in the population.

They reproduce more than others.

They get used to their environment.

Blue jays with thin beaks can reach inside pine cones and eat seeds. Blue jays with thicker beaks can easily open and eat seeds with hard shells. If their environment changes to only having seeds with pinecones which population of blue jays will be most likely to survive.

Populations 2 and 3 will be most likely to survive.

Populations 1 and 2 will be most likely to survive.

Only population 2 will survive because it is the only population with variation.

All the populations will survive because the blue jays will change the thickness of their beaks if they need to.

Foxes hunt squirrels for food. If they blend in with their environment they are better at getting closer to their prey to catch them. At Time 1 there were the same number of brown and white foxes. At Time 2 there were more brown foxes than white. How did the environment change between Time 1 and Time 2. How did the population change?

The environment became brown. With each generation, more brown foxes survived long enough to pass on the gene for brown fur to their offspring.

You cannot tell how the environment changed. With each generation more brown foxes passe on the gene for brown fur to their offspring.

The environment became brown. Brown foxes are more likely to survive, so white foxes changed to have brown fur.

The environment became brown. Brown foxes are more likely to survive, so both kinds of foxes passed on the gene for brown fur to their offspring.

What is correct about the rough skinned newts? (there are 3 that are correct!)

Something in the environment caused the newts to become more poisonous.

Poison level 10 is the most common in the newt population because newts with this trait were able to live longer.

Poison level 10 is the most common in the newt population because newts with this trait were able to reproduce more than other newts.n

The newts became more poisonous because they wanted to.

How do individuals in a population get their traits?

Genes for traits are passed down to them from their parents

How did the distribution in the snake population change?

The distribution in the red increased while the yellow decreased.

THe distribution stayed the same.

The distribution in the yellow increased while the red decreased.

The distribution remained constant.

The snake population went from having equal numbers of red and yellow snakes to having mostly red snakes. What may have caused the change in the snake population?

The environment they live in became more red.

The environment they live in became more yellow.

The environment they live in dried up.

The environment they live in stayed the same.
