ISB 202: Applications of Environmental and Organismal Biology

Learn why lipid-soluble signaling molecules like aldosterone only impact specific target cells. We discuss four theories and reveal that intracellular receptors present only in target cells are the key. This video demystifies the unique mechanism behind aldosterone's selective action.

Discover the evolution of plant-eating habits in insects, the links between moths, butterflies, caddisflies, flies, and fleas. Explore the hypothesis of how herbivory could influence speciation and diversity within the insect kingdom.

Unlock the world of pathogens, the microorganisms causing diseases. Grasp how they invade, colonize, and adversely affect host organisms. Learn about prevention strategies to mitigate their harmful impacts.

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.

Discover how filtration pressure is calculated within our bodies. Explore various options from adding capillary pressures to understanding lymphatic vessel roles. Grasp essential physiology principles as we highlight the accurate method.

Explore the distinctions between aerobic, anaerobic, and non-aerobic exercises. Understand the energy mechanisms driving each type of exercise and their unique health benefits. From jogging and sprinting to golf, discover how each engages the body differently.
