The correct answer is C. Passive transport refers to the movement of substances such as ions across the cell membrane without the use of energy. Examples of such movement is diffusion, facilitated diffusion, osmosis and filtration. The opposite of passive transport is active transport and this needs energy to occur. Examples of active transport are proton pumps, exocytosis and endocytosis.
Jellyfish, corals, and hydras belong to the group of animals called cnidarians.
The main characteristic of this group is that all of its members possess specialized cells called cnidocytes which often produce venom and have a role in capturing the animals prey.

Answer:
C.The added epitope disrupts the function of the tagged protein
Explanation:
When an additional sequence is tagged to a protein to use comercial antibodies, there are several reasons why this procedure wouldn't work as expected (note that we're assuming the protein is being expressed but it's not possible to detect it).
For example, the sequence of nucleotide added to codify for the tagged epitope are removed during the RNA processing. In that case, the protein would be expressed without the epitope, so it would be impossible to localize it with the antibodies.
Also, it could be that the new epitope is affecting some way the protein folding, making it not functional. This way, it would be degraded by the cell so it wouldn't be detected.
Another possibility is that the epitope doesn't affects the protein folding nor its function, but during the folding ends up in a conformation that makes it inaccesible for the antibody.
In summary, the way as the possible answers to this question are shown, the correct option seems to be C:<em> The added epitope disrupts the function of the target protein.</em>
