In this unit, we'll explore the foundations of life itself, learning about macromolecules from proteins to nucleic acids. By the end, you'll have a better understanding of the chemical properties that make life possible.
For the purpose of AP ®, you do not need to know the details of every biogeochemical cycle, though some details of those cycles are covered in this section. Information presented and the examples highlighted in the section support concepts outlined in Big Idea 2 and Big Idea 4 of the AP ® Biology Curriculum Framework.
Learn AP Biology using videos, articles, and AP-aligned multiple choice question practice. Review the fundamentals of biochemistry, cell biology, genetics, evolution, and ecology, and develop scientific thinking skills as you explore the study of life.
Cohesive forces cause the water molecules to stick together with a lot of elasticity, allowing the water to function very much like a rubber balloon so that when it is filled with air it doesn't break and simply forms a blanket over the air pocket.
Elements of life. Matter, elements, and atoms. Google Classroom. Learn about the structure of the atom, and how atoms make up matter. An atom is the smallest unit of matter that retains all of the chemical properties of an element. Introduction. What is your body made of?
Water takes up 333 million cubic miles on Earth, yet access to drinking water is a critical issue for many communities around the world. Explain why this is so. Drinking water is only obtained by rain water harvesting.
Be able to state the difference between a monomer and a polymer. Be able to name the four main classes of macromolecules and the monomers that compose them. Describe dehydration synthesis and hydrolysis reactions. Explain the properties of water and why they are essential to life.
