AP Biology

The pH curve is expected to reach its maximum reaction rate at a pH of about 7. This is because the optimum pH at which most enzymes act is in the range of 6 to 8 (mostly neutral). The pH of a substance reflects its acidity or concentration

This question is one of four free question answers (papers) on 2003 pre-university (AP) biology exams taken by over 105,000 high school students from about 6,000 AP biology programs around the world . In addition to the four paper questions, this example shows the breadth of the concept, and the student completes the multi-choice section with 120 questions. The AP biology test is based on the AP biology course taught by high school biological teachers at schools in the United States and around the world. The course is expected to be comparable to the second semester introductory biology course you studied at the university. Students who achieve a high enough score in the AP biology exam usually can earn up to eight semester credits at thousands of universities and universities in the US.

Subcommittee of university faculty and high school AP biological faculty appointed by the university council. Develop AP biology tests through management and technical assistance from Educational Testing Service (ETS). A typical test was developed over two years and received many drafts and corrections. Major readers of AP Biology will ask the development committee to decide whether they can answer and rate them freely and answer questions fairly and consistently. The Development Committee also posts the basic theme of AP biology on various publications that teachers can use in AP courses. The eight themes are "science as process", "science, technology, society", and "evolution and regulation". According to AP Biological Thematic Outline, these themes are divided into 25% for molecules and cells, 25% for genetics and evolution, and 50% for organisms and populations.
