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

Answer:
Explanation:
Can you think of a solid that can flow?
You use one twice a day! Toothpaste is a solid that can flow. Is the asthenosphere made of toothpaste? Only if the
toothpaste is ultramafic in composition, and then it would only be able to flow if it were really, really hot. Still the
toothpaste analogy gives you a good image of how the asthenosphere might behave if you squeezed it!
Lithosphere
The lithosphere is composed of both the crust and the portion of the upper mantle that behaves as a brittle, rigid
solid. The lithosphere is the outermost mechanical layer, which behaves as a brittle, rigid solid. The lithosphere is
about 100 kilometers thick. How are crust and lithosphere different from each other?
Accumulation of substances such as pesticides or other chemicals in an organism
