Q: Can I use a calculator on the AP Biology exam?
A: Yes, you can use a 4-function, scientific, or graphing calculator. And beginning in 2025, there will be a Desmos graphing calculator available in the Bluebook testing app. Important things to know:

In this lesson, we continue to explore the inheritance of genetic traits by learning more about the process of meiosis. View the video from 7:00-10:05 to learn about how the process of crossing over occurs.
Fermentation is included in topic 3.6 Cellular Respiration of the Course and Exam Description.
From NPR: In this episode, you're invited to the fermentation party! Join us as we learn about the funk-filled process behind making sauerkraut, sourdough and sour beer. Plus, no fermentation episode is complete without a lil history of our boy, yeast. Storyline Units: An Instructional Model to Support Coherence from the Students’ Perspective10/28/2024
Hey Storyliners!
I wanted to share this journal article as a lead-in to the next unit I'll be covering with my AP Biology students. Even after writing storyline units for AP Bio, I still have a lot to learn. This article by Reiser et al. is one that I've been meaning to look at in more depth. I'll be posting ideas about the strategies, activities and student work that I'm incorporating into Unit 4 to shift my teaching to more fully align with the framework of a storylining approach. Unit 4 can be a very challenging unit, so I'm using a phenomena this year that I hope will help to make the unit more coherent for students. I've shared this article with a group of teachers dedicated to implementing storylines in their classrooms and have asked for their feedback about some of the key ideas presented in the paper.

Bruce Lee became an international movie icon after starring in martial arts film including the iconic Enter The Dragon. He died in 1973 due to cerebral edema. A 2022 article proposed a hypothesis that Lee died because of hyponatremia.
During Unit 2 - Too Much of a Good Thing?, students will perform an experiment to investigate the process of osmosis and explore how different concentrations of salt water can affect biological tissues.
Read the paper about how hyponatremia may have caused Bruce Lee's Death.
Answer: The rate of photosynthesis will decrease as the amount of CO2 decreases.
Explanation: Plants need three things to carry out photosynthesis: water, carbon dioxide and light. 6CO₂+6H₂O+light→C₆H₁₂O₆+ 6O₂ It's like making sandwiches. The carbon dioxide is like bread, the water is like lunch meat and the products of photosynthesis (glucose, oxygen) are like a sandwich. It doesn't matter if you have loads of lunch meat - if you don't have any bread, you can't make any sandwiches! Here is a video which discusses an experiment which tests the impact of varying carbon dioxide levels on the rate of photosynthesis. Hope this helps!
Yes!
Explanation: Many sources say that genes are regions of DNA which store information used to code for proteins. While it is true that many genes store information used to code for proteins, it is not true that all genes store information used to build proteins. The modern definition of gene is a region of DNA which is transcribed. This includes genes in the tRNA and rRNA families. These DNA regions are transcribed to produce molecules of transfer RNA and ribosomal DNA. The three domain classification system (eukaryota, bacteria and archaea) proposed by Carl Woese in 1977 is based upon sequence data of rRNA genes. 
This video provides a review of how information in a gene that codes for a protein is retrieved and used by cells.
