I'm taking AP Bio right now and I've been working hard to study for the exam! I want to tackle the most challenging material possible. What are the hardest biology questions you've seen or can you recommend a resource to find them?
I'm glad to hear that you're looking to challenge yourself in AP Biology! Tackling difficult questions can help solidify your understanding and better prepare you for the exam. Here are two challenging questions that cover cellular processes and genetics, which you might find helpful:
1. Cellular Processes:
A cell at the beginning of the cell cycle has a mutation in its DNA that results in the production of nonfunctional cyclin-dependent kinase (CDK). If this cell were to attempt to proceed through the cell cycle, at which stage would the defect be most likely to cause the cell cycle to halt? Explain the role of the cyclin-CDK complex and its relevance in this situation.
2. Genetics:
A certain species of plant exhibits two traits, flower color and leaf shape. Flower color can be either red (R) or white (r), while leaf shape can be either broad (B) or narrow (b). A cross is made between two plants, one with red flowers and broad leaves (RRBB), and one with white flowers and narrow leaves (rrbb). The F1 generation exhibits all plants with red flowers and broad leaves (RrBb). What is the phenotypic ratio of the F2 generation plants when F1 plants are crossed among themselves? Explain how you arrived at the result using the concepts of independent assortment and dominance.
For more challenging questions and resources, I recommend visiting the official College Board AP Biology website, as they provide past exam questions, which are a great source of difficult problems. Additionally, you may consider using resources like CollegeVine, where you can find study materials and advice on preparing for the AP Biology exam.
Remember that practice makes perfect, so keep challenging yourself and working through tough problems. Good luck with your AP Bio exam!
