BIOL 199: Biology Orientation

Learn about the path of blood flow in the mammalian heart and circulatory system. Discover how oxygen-rich blood from the lungs enters the left atrium and understand why other statements about blood flow are incorrect.

Grasp the fundamentals of how neurons transmit electrical signals through action potentials. Understand the crucial role of myelination and fiber diameter in efficient nerve impulse conduction. Dive into the comparisons of different nerve fiber types and their properties.

Discover the concept of negative feedback loops in biological systems, where balance is maintained by counteracting changes. Explore the four key components: Stimulus, Sensor, Control Center, and Effector, through examples like blood sugar regulation. Uncover how these loops play a crucial role in keeping our body systems in harmony.

Explore the intricate components of the endomembrane system within a cell. Identify which structures belong to this system and which do not, with a specific focus on the unique role of the chloroplast.

Gain a clear understanding of chemical equilibrium, where reactant and product concentrations stay constant due to equal forward and reverse reaction rates. Dispel common misconceptions about equilibrium, such as concentration equality and reaction reversibility.

Explore the fascinating realm of organic chemistry and its emphasis on carbon compounds. Understand how organic molecules, pivotal to life, are intricately composed. Gain insight into the properties and relationships that make these compounds essential.
