BIO 121: General Biology

Explore the influential Three-Domain System of classification, introduced by Carl Woese in 1978. Discover how it categorizes life into Bacteria, Archaea, and Eukarya based on distinctive cellular structures. Learn about the characteristics of each domain, from prokaryotic Bacteria and Archaea to the rich diversity within Eukarya, encompassing Protists, Fungi, Plants, Animals, and the unique world of viruses.

Discover the relationship between the papillary layer of the dermis and the layers of the epidermis. Understand the structure, function, and connections that exist in our skin's anatomy.

Explore the sensory marvels of the male silkworm moth known as Bombyx mori and how they detect specific chemical signals from females. Uncover a hypothesis about the unique sensitivity of the moth's antennae and a prediction stemming from it. Learn how to design an experiment to test this hypothesis and deepen your understanding of insect behavior.

Unpack the intricate processes within photosynthesis and identify which is most directly powered by light energy. Discover the critical role of chlorophyll in capturing solar power.

Discover the debate between Intelligent Design (ID) and evolutionary science as they clash over the complexity of biochemical pathways in nature. Explore the concept of guided vs. unguided evolution and how diverse pathways challenge the ID perspective.
