• grassland

• taiga

What physical property(ies) is (are) the same for Cr and Mn?

• Ability to Burn only

• Ability to Rust only

According to the student’s observations, what can most likely be concluded about Section 1 of the garden?

• There is not enough sunlight for all of the seeds to germinate.

• There is not enough space for all of the seeds to germinate.

• There is not enough carbon dioxide for all of the seeds to germinate.

• There is not enough water for all of the seeds to germinate.

It has been estimated that more than 10 million beehives were lost in 2013 in the United States due to colony collapse disorder caused by the widespread use of pesticides. How will the decrease in the honey bee population affect the ecosystem?

• It will increase the percentages of almond and apple crops because insects other than honey bees will help pollinate these crops.

• It will increase the percentages of cotton and orange crops because these are less dependent on honey bee pollination.

• It will decrease the percentages of almond and apple crops because lesser numbers of honey bees are available for pollination.

• It will decrease the percentages of cotton and orange crops because the populations of other insects will also decline along with honey bees.

In early 2003, a forest in California experiences a record number of forest fires. The graph shows the population sizes of four species of plants in the forest.

Which species likely has seeds that are stimulated to grow by high temperatures?

• Species 1

• Species 2

• Species 3

• Species 4

How will the decrease in the surface areas of ice sheets most likely impact land animals living in the Arctic?

• The animals will have less breathable air.

• The animals will have less habitable space.

• The animals will have an increase in the availability of food.

• 
  The animals will have an increase in potential mates.

A scientist selects a small container and a large container and places two male and two female insects in each container with the same amount of nutrients. The number of offspring, referred to as pupa, is collected over the course of the experiment for several hours, as shown in the graph.

What can be concluded from the experiment?

• The population of insects in the small container is limited due to access to potential mates.

• 
  The population of insects in the large container is limited due to the spread of a disease.

• The population of insects grows quicker when there is less competition for space.

• The population of insects grows quicker when there is less competition for food.

Guanaco are related to camels but are native to South America. Graph A shows the change in the average winter temperature of the region where guanaco live, and Graph B displays changes in their population from 1980 to 2010.

Based on the graphs, what was the likely population of guanaco if the winter temperature during 2011 averaged 0.6°C above normal?

• 
  25,000 guanaco

• 
  35,000 guanaco

• 
  40,000 guanaco

• 
  50,000 guanaco

The graph shows the population of wolves and hare in a grassland.
