BIOL 145: Freshman Biology Seminar

Get insights into the role of lysosomes in different cell types. Find out which cell is the ideal choice for studying these powerful digestive organelles and why.

Explore the critical components of the Peripheral Nervous System (PNS), including nerves and ganglia. Understand the distinction between sensory and autonomic ganglia and the composition of nerves' layers. Learn why nerves and ganglia lack the protective meninges found in the CNS and how they facilitate essential signal transmission within the body.

Discover the mechanism of temporal summation in neurobiology. Understand the role of presynaptic and postsynaptic neurons in this process. Dive deep into the distinct mechanisms and their relevance in the nervous system.

Uncover why flamingos, genetically predisposed to white feathers, sport a pink hue. Dismissing influences like weather and DNA mutations, the mystery unravels with diet: the intake of carotenoids from their food which overrides their genetic blueprint

Discover the unique adaptations of C4 and CAM plants in photosynthesis. Understand their evolved strategies to fix carbon efficiently in challenging environments. Dive into nature's remarkable mechanisms of survival and adaptation.
