If the herring was eaten by something that either ate or was being eaten by the gulls, then they would be affected differently. If the gulls had less food because there food source had less food if the herring disappeared, then they would have a lower or population of perhaps become extinct. If the thing eating the herring became extinct because it had less food, then the gulls population would increase and either boom and bust or grow and level out once they reached the carrying capacity.
Answer:
B) Na+
Explanation: Na+ molecule is polar, oxygen and carbon dioxide are nonpolar molecules. The cell membrane is a <em>phospholipid bilayer</em> made up of lipid molecules with polar and nonpolar ends. Since it is a bilayer, two phospholipid layers are arranged, one on the other in such a way that one faces the back of the other. The non polar ends are away from outside and inside of the cell, while the polar ends faces towards all the molecules inside and outside the cell.
Since polar-polar molecules repel each other, Na+ can't pass through the cell membrane easily. So it uses the proteins attached the cell membrane inside and outside to transport such molecules by using energy in terms of ATP.

Answer: The correct answer is B) city hall:control center.
As per the question, model of cell looks like a city where different buildings correspond to different organelles ( membrane bound subcellular compartments like nucleus, golgi complex, vacuole, endoplasmic reticulum).
Nucleus is a specialized membrane bound compartment that possesses the genetic material ( DNA) of the Eukaryotes ( like plants and animals).
Nucleus controls all the essential activities of the cell by regulating the expression of gene ( segment of DNA corresponding to a particular protein).
Therefore, in the model of cell, city hall;control center represents the nucleus of the cell.
