What are two things that change the Earth's crust when a volcano erupts?
The hot magma from inside Earth is released at weak points in the crust and the volcano gets taller.

What are two pieces of data that support the idea that Pangaea once existed?
Animal fossils of one species found on multiple continents.
Similar mountain formations in North America and Europe.

What two types of natural resources are required to make bottled water?
Fossil Fuels
Freshwater

How do body cells in multicellular organisms reproduce?
Through mitosis.

What explains why so many fossils look different from the millions of species currently living on Earth?
Most species that have lived on Earth are now extinct.

How does the diagram below support the claim that these horse species are closely related to one another?
Their skeletons have many similarities.

Scientists hypothesize that a certain species of animal existed in the past, but fossils of the species have never been found. What are two reasons that could explain why the fossils are not found?
The bodies decomposed quickly.
There were very few members of the species.

In which region is there most likely to be a volcano based on the image below?
Region D - the Ring of Fire is in the Pacific Ocean.

What substance should be monitored and controlled to help minimize the impact of human activity on air quality?
Ozone

In the pedigree below, the red circle and squares indicate family members with a specific trait. Based on the pedigree below, who must be heterozygous for the trait?
Both parents must be heterozygous for the trait.

A wombat is a small, pouched mammal that lives in Australia. Wombats eat grass at night. They live in burrows and can run very fast. A female's pouch has milk glands to feed her babies. When a female is ready to mate, she releases a scent that male wombats can detect.
Which characteristic of wombats is most likely an adaptation for escaping predators?
They can run very fast
Muscular legs and shoulders contribute to this.

Look at the image below. Base on this image, what can you conclude about a fossil found in area D?
It is older than 2.1 million years.
400
What are two pieces of data that could indicate a volcano is about to erupt?
An increase in temperature near Earth's surface.
A change in the types of gas detected in the air.

Name two changes that could help a community reduce its use of fossil fuels.
Giving citizens money to install solar panels on their homes
Installing wind turbines in the region's windiest regions
Any effort of switching from nonrenewable to renewable energy

A scientist crosses a plant with red flowers and a plant with white flowers. Each plant is pure for its trait for flower color. The gene for flower color shows codominance, what coloring will the flowers of the offspring have?
White and red flowers.
400
How do you describe evolution in a population?
It is a change in how common a certain genetic trait of a species is from one generation to the next.
500
What can scietists learn from radiometric dating?
How long ago a plant or animal lived.
500
What magnitude would an earthquake have if there were major damage to buildings and deaths recorded?
9.0 or above.

Coal, oil, and natural gas are used as fuel. The graph shows changes in the per capita consumption of these three natural resources since 1820. What is the most likely result of this increased use of fossil fuels?
More greenhouse gases are released into the air, causing global warming.
500
How could gene therapy be used to treat diseases caused by mutations?
It could deliver a corrected version of a gene to the person's cells.
500
What are two ways scientists use evidence of past environments preserved in rock?
To confirm whether an organism could have lived where its fossils are found
To confirm that conditions in different places have changed
