When two protein chains combine to form an active protein, the structural level is quaternary.
<h3>What is a quaternary structure?</h3>
The quaternary and tertiary structure of a protein is the tridimensional shape of the protein, which involves protein domains.
The quaternary protein structure refers to the different arrangements generated by different protein subunits.
The primary structure of a protein involves its amino acid sequence, whereas the second structure involves protein chains.

Typical methods of classroom scientific communication depending on the level of study could include a range of these activities which have been listed in the answers. However, at the elementary, middle, and high school levels it would be safe to argue that the typical methods of communication are B) lectures, lab reports, term papers, and poster presentations.

The correct answer is 3- <span>The smelt and alewife may out-compete the native fish by consuming all of the zooplankton.
The diagram tells us that zooplankton is eaten by smelts and alewifes. If these two species increase in number, less of the zooplankton will be left for plankton-eating fish, which is a native type of fish, to eat.
</span>
<span> smelt and alewife eat most of the existing plankton so, they are out-competing the native fish.</span>
