Hawaiian honeycreepers (birds), consisting of 50 species, some of which are now extinct, represent a much more diverse lineage than hawaiian thrushes. honeycreepers have a remarkable variation in bill morphology, whereas hawaiian thrushes exhibit far less morphological variation. bill morphology is strongly linked to the resources available for these birds to eat. this suggests that in honeycreepers may have occurred as a result of

a) sexual dimorphism: leksb) allopatric speciation; hybrid zonesc) sexual selection; monogamous pair bondsd) adaptive radiation; dietary specializatione) adaptive radiation; poor dispersal ability

Which statements about the fluid mosaic structure of a membrane are correct? select the three correct statements.which statements about the fluid mosaic structure of a membrane are correct? select the three correct statements.the framework of a membrane is a bilayer of phospholipids with their hydrophilic heads facing the aqueous environment inside and outside of the cell and their hydrophobic tails clustered in the center.because membranes are fluid, membrane proteins and phospholipids can drift about in the membrane.the diverse proteins found in and attached to membranes perform many important functions.the kinky tails of some proteins keep the membrane fluid by preventing the component molecules from packing solidly together.membranes include a mosaic, or mix, of carbohydrates embedded in a phospholipid bilayer.
