The shaded areas of this diagram represent where fossils of a land- dwelling animal were found on the continents of South America and Africa. What does this evidence suggest?

• The animals swam from one continent to the other

• The two continents were once connected by a land bridge.

• The animals developed on the two continents at the same time.

• The two continents were once joined as part of a larger continent.

Darwin observed many birds that had many different beak shapes and sizes. There were few beaks that were similar because of…

• competition for the same type of food

• competition for a specific concentration of oxygen in the atmosphere

• the presence of an excessive number of autotrophs

• the presence of a disease that attacks birds with similar beak

You notice as you run up a flight of stairs to your next class that your heart is pounding and your breathing is deeper and more rapid than when you started. After a short time setting in class, your respiration rate and heart rate seem to return to normal. You know that during exercise, your heart rate, respiration, blood pressure, and ability to hold your breath (maximum breath-holding time) change. You gather the data shown in the table below. As you exercise, why does respiration rate increase?

• Your systolic blood pressure is increasing

• Your diastolic blood pressure is decreasing.

• You are sweating and need more water vapor.

• More oxygen is needed to utilize the body's stored energy.

Which of these elements is most likely to have chemical properties similar to those of calcium (Ca)?

• Magnesium (Mg)

• Neon (Ne)

• Potassium (K)

• Zirconium (Zr)

What is the relationship between water temperature and dissolved oxygen?

• as water temperature increase, dissolved oxygen increase

• water temperature has no effect on the amount of dissolves oxygen

• dissolved oxygen decreases as water temperature decrease

• cold water contain more dissolved oxygen than warm water

Which is best shown that two species evolved from a common ancestor?

• They are found in the same part of the world

• They eat the same types of food

• Their embryos develop in a similar way

• They have the same predators and parasites
