Consider your knowledge about the cell membrane and check all of the true statements below 1) cell membranes are present in only two of the three domains of life

2) in water, phospholipids spontaneously arrange into a bilayer

3) the area within a phospholipid bilayer, near the fatty acid tails, is hydrophilic

4) steroids in cell membranes allow the membrane to be more fluid

5) phospholipid bilayers surround all eukaryotic cells

6) membrane proteins offer structural support to the membrane but have no other function

7) both plant and animal cell membranes are considered fluid mosaics
