The adaptive advantage associated with the filamentous nature of fungal mycelia is primarily related to a) the ability to form haustoria and parasitize other organisms b) the potential to inhabit almost all terrestrial habitats c) the increased probability of contact between different mating types d) an extensive surface area well suited for invasive growth and absorptive nutrition

when you breathe in, or inhale, your diaphragm contracts (tightens) and moves downward. this increases the space in your chest cavity, into which your lungs expand. the intercostal muscles between your ribs also enlarge the chest cavity. they contract to pull your rib cage both upward and outward when you inhale.
