The answer is A because the total volume of gas wouldn't change (and oxygen consumption would be immeasurable) unless the carbon dioxide produced by the organisms were removed from the environment.
You can see this from the information contained in the question.
Your success on the AP Bio exam ultimately rests on your being able to connect specific concepts with the overarching Big Ideas that define the course. Main Point: The process of evolution drives the diversity and unity of life Topics Covered: Apart from background knowledge of all this content, it's important to understand your labs and the basic underlying principles that govern scientific experiments.
If you know the ins and outs of experimental design, you'll earn In this section, I'll give you some preliminary study tips that will help you get the most out of your AP Biology review time.
Here's a chart showing the format of the 2020 AP Biology exam: You now know the general format of the AP Biology test, but what do questions actually look like on it? These can be discrete (meaning they are stand-alone questions) or they can come in sets with other questions.
Here's an example of a multiple-choice question you might see on the exam: You don't necessarily need lots of in-depth biology knowledge to answer this.I recommend doing the short answers first to get yourself warmed up.Then, if you manage your time well, you should have at least 20-25 minutes for each long free-response questions. As a reminder, there are 60 multiple-choice questions on the AP Bio exam.From 2013 to 2019, the multiple-choice section of the AP Biology exam included six math-based grid-in questions.Starting in 2020, however, the exam will no longer have any grid-ins. On the second section of the AP Biology exam, you'll get four short-answer questions (in addition to two long questions).(More on how to manage this in the "How to Review" section!) The AP Bio exam and curriculum as a whole will be centered around your understanding of what the College Board refers to as its four "Big Ideas," each of which covers several different topics.Here, you need to be able to read and understand the graphs and table so you can use them to inform your answer to the question.Once again, an understanding of evolution and the ability to apply that knowledge to a specific scenario is critical.These questions focus on the following topics: Here's an example of a short free-response question from the 2013 exam: This question requires an understanding of how evolution shapes the formation of new species (one of the "Big Ideas" of AP biology, which I'll talk about in the next section).To get the correct answer, you'll need to know the facts about evolutionbut you'll also need to be able to apply that knowledge to make inferences about this specific scenario.
