Answer: Supplementary angles are two angles whose sum is 180 degrees while complementary angles are two angles whose sum is 90 degrees. Supplementary and complementary angles do not have to be adjacent (sharing a vertex and side, or next to), but they can be. ... The same is true for complementary angles.
Answer & explanation:
1. In the nitrification process, the oxidation of ammonia (NH₃) occurs, converting it to nitrite and, subsequently, to nitrate. This process is performed by chemosynthetic bacteria (also known as nitrifying bacteria), that is, they use the energy released in nitrification to synthesize their organic substances.
2. Denitrification occurs when bacteria in the soil called denitrifiers use nitrates and turn them into nitrogen gas. Denitrification ensures the return of nitrogen to the atmosphere.
3. The fixation of atmospheric nitrogen occurs mainly with the help of bacteria. These bacteria form nodules in the cortical region of the roots of these plants, where they act by capturing atmospheric nitrogen and transforming it into ammonia (NH₃), which will be used by plants.
The answer is eukaryotic cells

Humoral immunity is a situation in which antigen binds to antibodies. It is also called as the anitbody-mediated beta cellularis immune system that is found in the extracellular fluids (e.g. antibodies, complement proteins, antimicrobial peptides. Humoral immunity is mediated by macromolecules and is so named because it can be found in the humours or body fluids. <span>
