Leann is learning about chemical reactions. She wants to create a model of a chemical reaction, so she is examming the informati
butalik [34]

Answer:

  • B the kinds of molecules involved in the reaction
  • C the kinds of elements that make up a molecule
  • D whether the molecules are products or reactants

Explanation:

When modelling the chemical reaction, it is important that the process is explained such that people looking at the model understand what happened in terms of the reactants and products and how they came to be either.

Leann will therefore have to include the kinds of molecules involved in the reaction be they products or reactants. She will also have to include which elements make up the molecules for instance a water molecule would have the elements Hydrogen and Oxygen.

Finally she would have to indicate which molecules are reactant and which are products. Reactants usually stay to the left side of the reaction equation and products stay to the right.

When antibodies bind antigens, the clumping of antigens results from _______. A. the antibody having at least two binding region
Pani-rosa [81]

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
