Cells have many organelles to memorize and understand. One of the organelles that you must know for the AP® Bio exam is the cell membrane. In this AP® Biology Crash Course Review, we will go over the important information that you need to know for the AP® exam about cell membranes.
In this article, Endosymbiosis: AP® Biology Crash Course, we will start by reviewing the theory itself. We will then present the evidence that scientists have collected in support of the theory. Finally, we will go over a free response question that was seen on the 2011 AP® Bio exam.
When you hear the word dehydration, you undoubtedly think back to the last time you felt thirsty, dizzy, and generally off after a major loss of water (and insufficient water intake). Though we typically view the word dehydration in a negative light, the concept of dehydration synthesis is extremely valuable at the molecular level.
Proteins, along with carbohydrates and lipids, are a type of organic macromolecule that is a fundamental building block of life. While you hear a lot about proteins in daily living – like in ads for protein shakes and protein powders– there are a few misconceptions about why proteins are important and how they work.
Do you know your classical Mendelian genetics inside and out? If not, then read on, because Mendelian genetics is always a crucial part of the AP® Biology Exam. All forms of life are composed of DNAs, which Mendelian genetics can explain, and this crash course can help you out with the studying.
Diffusion and osmosis are two of those mechanisms that you will see pop up over and over again in your biology lessons as they are crucial to so many aspects of life. Throughout this quick crash course, we’ll give you the run-down of all the essential points you’ll need to know not just to prepare for the AP® Biology exam, but also to better understand the ‘big picture’ of how biology works.
One of the major topics on the AP® Bio exam is homeostasis. Most of the topics that you study in AP® Biology will force you to think: how does this relate to homeostasis? It is essential that you understand homeostasis completely and are able to relate it to a variety of topics.
In this AP® Biology crash course we will be talking about the endocrine system. The endocrine system is a system that regulates the secretion of hormones in order to control the body and mind. This system allows our bodies to do certain functions and have certain emotional states. All over our bodies are glands and vital organs that are controlled by the brain to direct our flow of hormones to allow life to happen.
Lipids have gotten a bad reputation over the past few years due to all the hype about fats being bad, but in reality, lipids are much more than just “fat.” They are, in fact, one of the building blocks of life. In this crash course review, we will go over everything you need to know about lipids to not only be prepared for the AP® Biology exam but also to better understand what an important role lipids play in biology as a whole.
The AP® Biology exam has a lot of content on DNA, and DNA replication will be a topic that you will be tested on so it is very critical to know it! In this AP® Biology Crash Course Review we will go over what you should know about DNA replication for the AP® Biology exam.
