AP Biology Reading Guide Chapter 6: A Tour of the Cell (2023) Why are cells so small? Explain the relationship of surface area to volume. 9. Describe how many neurons and intestinal cells each have greatly increased surface area. Concept 6.3 The eukaryotic cell’s genetic instructions are housed in the nucleus and carried out by the ribosomes 10. In the figure below, label the nuclear envelope, nuclear pores, and pore complex. 11. Describe the nuclear envelope. How many layers is it? What...

AP Biology Reading Guide Chapter 15 and 16: Regulation of Gene Expression & Development, Stem Cells and Cancer. List the three components of an operon, and explain the role of each one. The operator is the “switch” that controls what attaches to the promoter. The promoter lets transcription happen when RNA polymerase attaches to it. And the genes are responsible for coding for the correct protein. 11. Distinguish between inducible and repressible operons, and describe one example of eac...

AP BIOLOGY Control of Gene Expression in Prokaryotes Control of Gene Expression in Prokaryotes How do prokaryotes use operons to control gene expression? Why? Houses usually have a light source in every room, but it would be a waste of energy to leave every light on all the time, so there are switches to turn off the lights in rooms that are not in use. Sometimes one switch controls several lights in the same room. Likewise, prokaryotic cells can turn genes on and off based on environme...

AP BIOLOGY 24 MASS EXTRICTIONS POGIL KEY Why? Mass Extinctions What is the biological significance of mass extinctions? Evidence suggests that five mass extinctions have occurred throughout the history of the Earth—the most famous of which led to the extinction of the dinosaurs. Scientists are still studying the causes of these catastrophic events. What can we learn from mass extinctions, and what is their impact on the diversity of life forms found on Earth? Model 1 – Extinction Ov...

This book evolved from a course in molecular biology which I have been teaching primarily to graduate students for the past twenty years. Because the subject is now mature, it is possible to present the material by covering the principles and encouraging students to learn how to apply them. Such an approach is particularly efficient as the subject of molecular genetics now is far too advanced, large, and complex for much value to come from attempting to cover the material in an encyclopedia-like...

AP biology review cheatsheet for when you don't want to read unnecessary things in your book.

I used this study sheet for the second exam in Johanna Choo's Biology for Engineers class at UMass Lowell. I got a 100 on this exam. I highly suggest you print out the document, read it over, and mark important information to make things easily accessible during the test. This is good for AP Bio, freshman biology, or any other introductory biology courses!

I used this study sheet for the first exam in Johanna Choo's Biology for Engineers class at UMass Lowell. I got a 93 on this exam. I highly suggest you print out the document, read it over, and mark important information to make things easily accessible during the test. This is good for AP Bio, freshman biology, or any other introductory biology courses!

I used this study sheet for the third exam in Johanna Choo's Biology for Engineers class at UMass Lowell. I got a 92 on this exam. I highly suggest you print out the document, read it over, and mark important information to make things easily accessible during the test.
