D
Explanation:
The organelle that modifies proteins is the golgi body.
Answer:
The correct answer is option d. "Polyclonal antibodies".
Explanation:
The enzyme-linked immunosorbent assay (ELISA) is very useful in comparison to other immunoassay methods for being highly accurate, sensitive and specific. Polyclonal antibodies for the detection step could be used on order to ensure that a mutation in a single surface protein would not make obsolete an ELISA used to detect a new viral pathogen. Unlike monoclonal antibodies, polyclonal antibodies are a collection of antibodies that recognize multiple epitopes of the same antigen. Therefore, a mutation in one epitope that affects the binding of one antibody would not affect the bind of the others and the ELISA will be able to recognize the pathogen.
Photosynthetic organisms use sunlight to provide the energy necessary to combine carbon dioxide and water to form organic molecules and ATP. Those same photosynthetic organism also use cellular respiration to breakdown those organic molecules whenever there is an energy demand greater than what can be provided by photosynthesis or in the absence of light.
I believe the answer to your question is C, correct me if i'm wrong :)
