question 84

Multiple Choice

• B) Observe the organelle with freeze-fracture electron microscopy.
• C) Isolate the organelle using cell fractionation, and follow with further biochemical analysis.
• D) Use a chemical against actin to prevent organelle transport within the cell and observe the resulting cellular function.
• E) Use a detergent to break up the lipid membrane of the organelle in the cell, and observe the resulting cell function.

The total value, in current market prices, of all the final goods and services generated within a country's borders over a certain time period.

Real GDP

Real GDP, which adjusts for price changes to offer a true measure of an economy's overall size and its growth trajectory.
