Answer:
Explanation:
Ammonia is removed from an aquarium system through the use of a biofilter. The biofilter provides a substrate on which nitrifying bacteria grow. These nitrifying bacteria consume ammonia and produce nitrite, which is also toxic to fish. Other nitrifying bacteria in the biofilter consume nitrite and produce nitrate.

Answer:
a. Reduced siRNA-mediated mRNA degradation
Explanation:
The TRBP (transactivation response element RNA-binding protein) is an RNA-binding protein that forms the Dicer complex, which is involved in epigenetic pathways such as those mediated by the RNA interference (RNAi) mechanism. RNAi is a key process where small non-coding RNAs such as, for example, small interfering RNAs (siRNAs) and microRNAs (miRNAs) can inhibit target gene expression at posttranscriptional level by different mechanisms (including the degradation of target mRNAs). A null mutation of this cofactor will alter the Dicer complex, thereby also affecting RNAi pathways mediated by small interfering RNAs.
Answer:
Flocking (birds) and cooperative hunting (lions or wolves)
Explanation:
In large animal groups, social behavior enables to obtain an evolutionary advantage over non-social species by making decisions that are likely to be beneficial for the group. In humans, a comprehensive understanding of these benefits has shown to be useful in different areas ranging from social to economic systems.
Cooperative Hunting is a social behavior that enables predatory social species like lions to hunt larger organisms, thereby improving the adaptive fitness of individuals.
Bird flocking is another type of social behavior in which a group of bird is in flight. This behavior is shared by very different species such as insects and fish. Flocking has shown to be beneficial to individual birds to take care of predators and to find food.
