Ribosomes are attached to<span> the </span>membrane<span> of the </span>ER, making it “rough<span>.” The RER is also </span>attached to<span> the nuclear envelope that surrounds the nucleus.</span>
The graph which best represents this phenomenon is graph C.
The result of disruptive selection is the selection of the most extreme phenotypes/genoypes, and the decrease of the middle terms.
I believe once the vesicle has budded from the golgi body the clathrin coat is lost. During budding the membranes and proteins are moved around the cell in small vesicles. A protein coat aids the budding of these vesicles from donor membranes, The major type of coat used by the cell is comprised of clathrin; a three legged protein that can form lattice-like coats on membranes destined for trafficking.
