Which equation correctly shows the reactants and products of photosynthesis? A C6H12O6 + 6CO2 --> 6O2 + 6H2O B C6H10O6 + 6O2
scZoUnD [109]

The right option is D 6CO2 + 6H2O --> C6H12O6 + 6O2

This equation shows that carbon dioxide and water are used with light energy to produce glucose sugar and oxygen gas.

Photosynthesis is a process by which plants and other autotrophs use energy from sunlight to produce nutrients from carbon dioxide and water. Plants absorb water through the roots, carbon dioxide from the air, and light energy from the Sun, to produce glucose and oxygen.

The antigen-binding sites of an antibody molecule are formed from the molecule's variable regions. why are these regions describ
tino4ka555 [31]

The antigen-binding sites of an antibody molecule are formed from the molecule's variable regions which are described as so because their amino acid sequences can be different on different antibodies.

The specificity of antibodies is determined by the variable regions found at their endpoints. Antibodies are specialized proteins secreted by B-cells of the immune system. They are also called immunoglobulins. They contain four polypeptide chains that comprise two heavy chains and two light chains to form a Y-shaped molecule.

The variable regions, more specifically the hypervariable regions of an antibody, have a high ratio of different amino acids with the most common amino acids provided in one place. The variable region serves as the antigen-binding site while the constant region found below the variable region is determined to invade the antigen.

Antibodies are preserved in our body to identify the antigen the next time it encounters. They send the signals to the other body parts to reject the antigen and invade it.

To know more about variable regions of antibodies, refer to the following link:
