C, because it protects the cell from the outside environment
Answer:
A relationship between unrelated organisms in which oneorganism get benefit and the other is not affected is known as commensalism.
Explanation:
In commensalism organism live in a symbiotic association. the best example is the growth of epiphytes on the top or surface of orchid plants. The epiphytes obtain nutrients from orhids while in return orchids have no benefit from epiphytic plants.
Explanation:
Water molecules from the less conentrated right side, will flow into the left side til they equilibrate- at equilibrium both sides will have the same concentration of solute.
In diffusion small water molecules can move across the phospholipid bilayer acts as a semi-permeable membrane into the extracellular fluid or the cytoplasm which are both hydrophilic and contain large concentrations of polar water molecules or other water-soluble compounds. Similarly, during osmosis the water passes through the membrane due to the difference in osmotic pressure on either side of the phospholipid bilayer, this means that the water moves from regions of high osmotic pressure/concentration to regions of low osmotic pressure /concentration.
