Document Summary
Meroplankton: forms that spend only part of their lifecycle as plankton. Lab 2: taxonomy and citizen science bumblebees and terrestrial invertebrates. Mx = [dx a (cext cint)] / l. Mx = mass of gas x transferred per unit time (rate of diffusion) Dx = diffusion coefficient (measure of ease of diffusion, dependant on size of molecule and solubility coefficient; constant for a given gas and respiratory medium) Cext cint = concentration gradient across diffusion barrier. Gills are an effective solution to obtaining oxygen because gills are typically a thin-walled process, well supplied with blood that"s allows diffusion to occur between the fluid and the environment (water). Applying fick"s law, a thinner diffusion barrier and greater surface area in which are present in gills allow for more oxygen transfer and respiration to occur to increase the mass of oxygen transferred per unit time.
