My best guess would be c because b makes no since we as humans do not have photosynthesis and are considered living organisims, d is also wrong because the brain requires oxygen, and its not a because the brain is made of cells.
Answer:
osmolarity depends upon molarity.
glucose is a non-ionizing substance. it won't break down and will go as a whole.
osmolarity means the solute concentration of a solution.
here, the solvent is water.
therefore, 1 osmole = 1 mol
the ions of glucose after forming a solution (i) = 1
osmolarity = 1.5 M glucose × 1
= 1.5 osmoles of glucose.

The correct answer is antigens and epitope.
An antigen is a substance which triggers an immune response in an organism. This can be either a foreign substance, such as a pathogen, or a specific part of the host organism (in this case this is an autoimmune response). The presence of an antigen activates a specific part of the immune system, called antibody. Each antigen has a specific antibody, which is tailored by the immune system accordingly. More specifically, the antibody has a specific structure, called paratope, which is complementary and binds like a key to a specific structure of the antigen, called epitope.
