Your science teacher asks you to build a model of a cell. the model should look like a city, and buildings in the city should represent parts of a typical cell. each building's real-life function should be like the function of the organelle it represents. for example, the vacuole of a cell, which stores water, could be a water tower in your cell city model. what building should represent the nucleus, and why?
a)
factory: manufacturing
b)
city hall: control center
c)
power plant: provides energy
d)
highways and streets: transportation

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.

answer: accepted answer: aquatic animals use the oxygen dissolved in water to carry out respiration. since the amount of dissolved oxygen in water is low as compared to the amount of oxygen in the air, therefore the rate of breathing in aquatic animals is much faster than it is in terrestrial animals.
