Here's an overview of what to expect: Grid-in questions ask you to integrate math and science skills to make calculations and then enter your answer into a grid on the answer sheet (essentially, these are short-response questions that are similar to grid-in questions on the SAT Math section).The second section is the free-response section, which looks like this: The AP Biology test doesn't include a set number of questions that deal with each topic area, but you should note that the exam is centered around four major themes (or "Big Ideas," as the College Board calls them)."Researchers investigated the effect of light "on mouse behavior by using a running wheel "with a motion sensor to record activity "on actograms, as shown in figure one." All right, so let's think about what figure one is showing us.

The main part of the question asks what will be affected when you replace a hydrophilic amino acid with a hydrophobic one on a hemoglobin protein.

Based on your knowledge of sickle cell anemia and molecular properties, you should be able to eliminate choices B and C, which don’t have much to do with the abnormality described in the question.

And every day we're also ending our activity at an earlier hour.

And there's a lot more, I guess you could say, sporadic activity going on. All right, let's see if we can answer the questions.

I can draw, I can show a line that goes something like this.

You can see every day we are starting activity at an earlier hour. And then when we have the black line from hour 12 to hour 24, that means we are detecting activity on the running wheel and so we can assume that the mouse is active.And then we have it again for day two, and the way this is set up, it looks like that pattern holds for every day. "For the investigation, "adult male mice were individually housed in cages "in a soundproof room at 25 degrees Celsius." So they wanted to make sure that these mice didn't bother each other, that this was definitely controlled conditions."The nervous system plays a role in coordinating "the observed activity pattern of mice "in response to light-dark stimuli." Yes, that makes sense, of course. "Describe one role of each "of the following anatomical structures "in responding to light-dark stimuli." A photoreceptor in the retina of an eye. "The mice were exposed to daily periods "of 12 hours of light," with the capital L, "and 12 hours of dark," capital D. So that's 12 hours of light, 12 hours of darkness, "for 14 days, and their activity "was continuously monitored. "The activity data are shown in figure two." All right, so this is an actogram of mouse activity under L12, D12 conditions. There's a few gaps right over here, but for the most part, the mouse is active when it's dark. Less continuous, there's definitely more times where the activity periods is broken up by inactivity or the inactive periods is broken up by activity. - [Voiceover] "Many species have circadian rhythms "that exhibit an approximately 24-hour cycle."Circadian rhythms are controlled by both genetics "and environmental conditions, including light.The first sentence is background information that isn’t really necessary for answering the question, besides the fact that it tells us we’re talking about sickle cell anemia.This is helpful if you can remember basic facts about the disease that you can use to contextualize the question.
