I believe its A because all the other one dont make scene really.
The cell membrane is composed of a phospholipid bilayer.
The cell membrane is primarily composed of a mix of proteins and phospholipids
Phospholipids are a major component of cell membranes. They a head and a tail. The head is hydrophilic (attracted to water) and the tail is hydrophobic (repelled by water).
They form a bilayer in which their hydrophilic heads face the aqueous cytosol and extracellular fluid while their hydrophobic tails face away from the cytosol and extracellular fluid.
The lipid bilayer is semi - permeable
The real answer is B. Facilitated transport.
The urine osmolality is the measurement of urine absorption,
which substantial values indicate concerted urine and small values specify
weaken urine. Any foods that contained water also affects the osmolality of
urine. Some of the mammals are competent
of higher osmolality than healthy humans, most especially the rats, hamsters,
and mice if given no water.
