Planting seeds to shallow or too deep will prevent their growth as the seeds will get very little nutrients. If the seeds are planted to shallow the roots will not be able to absorb all the nutrients in the soil. Or when it rains due to the shallowness it will get too much water and die. If planted too deep part of the seeds will not receive water to grow and will die.
When antibodies bind antigens, the clumping of antigens results from the antibody having at least two binding regions.
What's the function of the antibody-antigen complex?
Antibodies serve two primary functions: selective binding to antigens to initiate an immune response and activation of other immune system components to combat infections.
- Immunoglobulins' capacity to combat a wide range of diseases is based on their inherent ability to distinguish between distinct antigens.
- Because of their antigen specificity and affinity, antibodies have shown to be a significant and important tool in research, diagnosis, and treatment.
- Although it appears to be a straightforward move, the connection of an antibody and its antigen to form an antigen-antibody complex is made up of a plethora of non-covalent interactions.
Hence, the correct answer is option A

I'm not sure if there were choices here but I would fill in something like "logically" or "scientifically".
Hope that helps.
