A student states that this structural formula represents a hydrocarbon. A C atom is bonded above, below, and left to H, and to the right to a second C, which is in turn bonded to the right to an O; the O is bonded to the right to H. Is the student correct? Yes, a hydrocarbon is any compound that contains a carbon backbone. Yes, a hydrocarbon is any compound that contains hydrogen and oxygen. No, a hydrocarbon contains only carbon and hydrogen atoms. No, a hydrocarbon contains at least one double or triple bond.

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.
