Try our free AP Biology unit 1 practice test. This unit introduces the structure and function of the chemical components of life. An understanding of the major biological macromolecules’ structure and function is a key focus in this unit.
AP Biology Unit 1. The figure shows a model of the exchange of matter between the organisms that live together in an aquarium. The model includes matter exchange between plants, fish, and bacteria. The bacteria are represented as rod-shaped organisms living in the gravel at the bottom of the aquarium. (Diagram shows fish giving off ammonia and ...
The Chemistry of Life unit explores the fundamental building blocks of living organisms, from atoms and molecules to complex macromolecules. It covers the properties of water, chemical bonds, and the structure and function of organic compounds essential for life, including carbohydrates, lipids, proteins, and nucleic acids.
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.
Biology Practice Exam From the 2013 Administration This is a modified version of the 2013 AP Biology Exam. • This practice exam is provided by the College Board for AP Exam preparation. • Exams may not be posted on school or personal websites, nor electronically redistributed for any reason.
The ammonia molecules released by the fish are converted by the bacteria to nitrates, which are used by the plants to make proteins and nucleic acids. Students conducted a controlled experiment to investigate whether sawdust provides enough nutrients to support plant growth.
Using the properties of water, describe how water can move up a capillary tube to move from the roots to the leaves in a plant. Cohesion due to hydrogen bonding contributed to the transport of water and dissolved nutrients against gravity in plants.
