For a fish to be buoyant, or float, it must displace less water or the same amount of water as its own body mass. ... Many fish use swim bladders to help them with quick depth changes.

Answer: The correct answer for the fill in the blank is B) RNA and Proteins.
Ribosome is a molecular machinery, which is located in all living cells. It is formed from proteins and complexes of rRNA ( ribosomal RNA). That is why, it is also called as ribonucleoprotein.
Ribosome serves as the site for protein synthesis. It is primarily divided into two subunits, a larger ribosomal subunit and a smaller ribososmal subunit, which together assist the process of protein formation ( translation).
Thus, the components of ribosomes are RNA and proteins.

Explanation:
Dual distribution is a method of distribution or arrangement, whereby a company uses majorly two approaches simultaneously in distributing their products to their end-users.

According to the information given in the question above, we can infer that the method of distribution used by pharmaceutical companies is an example of <em>dual distribution.</em>
