Explore the vital roles of pharyngeal slits in lancelets and tunicates. Learn how these clefts aid in filter-feeding, capturing food particles, and evolve through different life stages.

Explore the multifaceted roles of the skin, from protective barrier functions to sensory reception. Understand the distinction between the epidermal and dermal layers. Appreciate the comprehensive functionalities of the integumentary system.

In cell biology, the "driving ion" is a pivotal concept. It refers to ions moving from areas of high to low concentration, generating energy for various cellular transport processes. This gradient is crucial for nutrient uptake and waste elimination. Multiple processes involve a driving ion, including facilitated diffusion, symport transport, primary active transport pumps, and cotransport. Facilitated diffusion aids molecule movement along their gradient, while symport moves multiple substance
