IB 101: Biodiversity, Ecology, and Environmental Science

Explore the effects of isotonic, hypertonic, and hypotonic solutions on plant and animal cells. Understand water movement, solute concentration dynamics, and the resulting cellular changes, including turgidity in plants and crenation or lysis in animals.

Explore the underlying causes of muscle fatigue and the crucial role of lactic acid. Understand the impact of ATP depletion and anaerobic metabolism on muscle performance. Gain insights into planning effective exercise and recovery strategies.

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.

Explore stromatolites, the oldest indicators of life on Earth formed by microbial actions. Understand their presence in shallow marine environments and their connection to early eukaryotic life.

Explore the body's fight-or-flight response and its link to caffeine's effects. Learn how the interruption of cAMP phosphodiesterase leads to prolonged alertness and why caffeine can result in sleeplessness.

Explore the intricate process of mitosis and the crucial role it plays in cellular division. Learn how cell cycle control mechanisms, including cyclin degradation and Maturation Promoting Factor (MPF) activity, ensure accurate and regulated cell division.
