Scientists measured the spot size of all the guppies (small fish) that lived in a river 40 years ago. They measured the spot size of the guppy population again last year. When was there more variation in the spot size of guppies in the river?

• These bar graphs do not show the amount of variation in the population.

• There was the same amount of variation in spot size 40 years ago and last year.

• There was more variation 40 years ago.

• There was more variation last year.

Which is true according to the graph?

• Between month 1 and month 5, the population size was zero.

• Between month 4 and month 6, a predator was introduced into the ecosystem and increased the death rate.

• Between month 5 and month 7, the birth rates decreased and the death rates increased.

• Between month 8 and month 12, the population size showed a drastic decrease

Scientists measured the spot size of guppies (small fish) in two different populations. Which population has more guppies with large spots?

• They both have the same number of guppies with large spots.

• The population in Brazil has more guppies with large spots.

• The population in Venezuela has more guppies with large spots.

• These bar graphs do not show which population has more guppies with large spots.

Hummingbirds can have different beak lengths. They use their beaks to reach to the nectar (their food) at the bottom of flowers. Hummingbirds with longer beaks can get food from long flowers. Hummingbirds with shorter beaks cannot reach the nectar in long flowers. If a hummingbird can’t easily reach its food, it will die. The diagrams below show three possible hummingbird populations. If their environment changes to have only long flowers, which of the following hummingbird populations will most likely survive?

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

• All the populations will survive because the hummingbirds will change the length of their beaks if they need to.

• Populations 1 and 2 will survive.

• Populations 2 and 3 will survive.

Scientists measured the spine size of a population of cactuses found in an area in 1970. They measured the spine size of the cactus population again in 2015. Which of the statements below best describes the difference in the cactuses at the two time points?

• The cactuses in 1970 had smaller spines than the cactuses in 2015.

• The cactuses in 1970 had larger spines than the cactuses in 2015.

• There were more cactuses in 1970 than there were in 2015.

• There was more variation in spine size in 1970 than there was in 2015.
