To investigate the claim that exposure to light overrides the genetically-controlled circadian rhythm, the researchers plan to repeat the experiment with mutant mice lacking a gene that controls the circadian rhythm. So under some mutant mice, mutant mice, under, so let me make two columns, mutant mice under L12, L12: D12, and then under continuous, continuous darkness, what would I expect? They didn't get, this isn't a gene that somehow makes them not sensitive to light.
Predict the observed activity pattern of the mutant mice under L12: D12 conditions and under DD, continuous darkness conditions, that would support the claim that light overrides the genetically-controlled circadian rhythm. So I would assume under the L12: D12, they would behave, they would have activity pattern similar to non-mutant mice, activity same as non-mutant, as non-mutant, mutant mice, non, or inactivity, inactivity during L12, activity, activity during D12. They still could react to the light and the darkness the same way that a non-mutant mice would. The non-mutant mice, we said that they, they went off of a 24-hour cycle, but they still had a cycle where they were inactive, active, inactive, active, and it was less than 12 hours for each cycle, but it was close to it.
And then the second one is, if you're more likely to be eaten, then you're less likely to reproduce.
If, actually that should be capital I, if, if the mouse is more likely to be eaten by being active during the day, then it is less likely to reproduce, then it is less likely to reproduce.
Remember that the AP Biology exam tests you on the depth of your knowledge, not just your ability to recall facts.
While we have provided brief definitions here, you will need to know these terms in even more depth for the AP Biology exam.
These questions are based on the four "Big Ideas" described in the official course description.
Questions may focus on using modeling, math, predictions, experiments and data to explain biological concepts.
And if I were, if I were taking the AP test here, I would try to put as much context as possible, because you're not exactly sure how they're, they're going to mark this thing, to grade this thing, so you could give more context that therefore, the mice that are active during, therefore, therefore, mice that are active during night, they have to be active sometime, active during night and inactive during day will be selected for, will be selected for, less likely to be eaten, less likely to be hunted, I guess you could say, and more likely to reproduce, more likely to reproduce, reproduce, and we are done.
Advanced Placement Biology (AP Biology or AP Bio) is an Advanced Placement biology course and exam offered by the College Board in the United States.
