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.

a few examples of ethical concerns involving genetically engineering of humans include

-privacy of genetically tested people

- potential side effects

-long term effects
