The table shows the changes in size of the populations of grasses, shrubs, and trees over 150 years.

What type of succession was taking place?

• primary succession because trees replaced bushes

• secondary succession because the type of species changed twice

• primary succession because there was a decrease in the number of species

• secondary succession because the first organisms to grow were grasses

In order to make hydrochloric acid, which is required in human digestion, ATP is used to move hydrogen ions from the blood to the stomach lining. This is an example of ___.

• Passive Transport
• Osmotic Potential 
• Facilitated Diffusion

Scientists have studied organisms near steel mills. In one study, the scientists compared the DNA of two groups of mice. One group lived near a steel mill, and the other group lived in a rural area away from the steel mill. The scientists collected data on the number of mutations occurring in each group and created the table shown.

Which prediction can be made from this data?

• Mice that live in rural areas will have more genes expressed than mice near steel mills.

• Mice that live near steel mills will have more genes expressed than mice in rural areas

• Mice that live in rural areas will have higher rates of abnormalities due to mutations than mice near steel mills

• Mice that live near steel mills will have higher rates of abnormalities due to mutations than mice in rural areas.

 A paramecium is shown.  This paramecium lives in an environment where water is constantly entering the organism.  The paramecium uses specialized vacuoles to pump some of the water back into the environment against a concentration gradient. Which of these processes is used to pump extra water out of the paramecium?   

• Osmosis
• Diffusion
• Active Transport
• Electron Transport
