About
This quiz comprehensively covers fundamental concepts from the first three units of Advanced Placement Biology, targeting 11th and 12th grade students who have already mastered basic biological principles. The questions assess students' understanding of cellular energetics, molecular transport mechanisms, photosynthesis, cellular respiration, population genetics, and experimental design. Students need a solid grasp of biochemical processes including ATP hydrolysis and active transport, the light-dependent and light-independent reactions of photosynthesis, the Calvin cycle, and how energy flows through biological systems. They must understand membrane permeability and selective transport, buffer systems and pH regulation, genetic drift and population bottlenecks, and be able to interpret experimental data involving chloroplast function and DCPIP reduction. The quiz requires students to analyze graphs, predict experimental outcomes, and connect molecular-level processes to organism-level phenomena, demonstrating the complex reasoning skills essential for success in college-level biology. Created by Jessie Byrne, a Biology teacher in the US who teaches grades 9-12. This comprehensive assessment serves as an excellent review tool for students preparing for their AP Biology exam, covering the essential concepts from Units 1-3 that form the foundation for more advanced topics later in the course. Teachers can use this quiz as a formative assessment to identify knowledge gaps before moving into Unit 4, as a homework assignment to reinforce recently covered material, or as a warm-up activity spread across multiple class periods. The varied question formats, including data interpretation and experimental analysis, make it ideal for helping students practice the scientific reasoning skills they'll need on the AP exam. This quiz aligns with AP Biology Learning Objectives including ENE-1.A (explain how the structure of biological membranes influences selective permeability), ENE-1.K (describe the processes that allow organisms to use energy stored in biological macromolecules), EVO-1.G (describe how changes in genotype frequency in populations occur due to the mechanisms of evolution), and SYI-1.F (explain how biological systems use energy).

Undersea landslides can disrupt marine habitats by burying organisms that live on the ocean floor. The graph above shows the size of a population of a certain organism that lives on the ocean floor. The population was affected by a recent landslide at the time indicated on the graph. Which of the following best predicts how the population will be affected by the landslide?
The surviving organisms will evolve into a new species.
The reduced population will likely have allelic frequencies that are different from the initial population.
The population will adapt to deeper waters to avoid future landslides.
The reduced population will have a greater number of different genes than the initial population.

The equation above shows one of the reversible reactions that occur in blood. After exercise, an athlete’s blood pH has dropped below the normal level. How will normal blood pH be restored?
H+ + HCO3– ↔ H2O + CO2
An increase in O2 concentration in the plasma will lead to an increase in H+ concentration.
An increase in temperature will lead to an increase in H+ concentration.
An increase in sweating will lead to a decrease in OH– and H+ concentration.
An increase in breathing rate will lead to a decrease in blood CO2 and H+ concentration.

What most likely causes the trends in oxygen concentration shown in the graph below?
The water becomes colder at night and thus holds more oxygen.
Respiration in most organisms increases at night.
More organisms are respiring at night than during the day.
Photosynthesis produces more oxygen than is consumed by respiration during the day.
