BIOLOGY 0001: General BIOLOGY I

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.

Learn the distinctions between dispersal and vicariance in biology. Understand how organisms' movements and environmental changes play crucial roles in allopatric speciation. Grasp the differences between movement across existing barriers and the creation of new barriers.

Explore the concept of semiconservative DNA replication, where each new DNA molecule retains one original strand. Understand the significance of this mechanism in ensuring accurate genetic information transfer across cell generations.

Discover the science behind thermoregulation, focusing on endotherms and ectotherms. Understand how internal metabolic processes distinguish endotherms, while ectotherms rely on environmental factors. Highlighting the adaptations each group has evolved to thrive in their habitats.

Unlock the intricacies of kidney function as we focus on the role of nephrons and their specific components in regulating water recovery or disposal. Understand how collecting ducts are the main player in this process and debunk common misconceptions about other nephron parts.

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.
