Final answer:
In the analogy between a city and a cell, wastewater would be more likely a part of exocytosis, which is the process of expelling material from the cell.
Step-by-step explanation:
In the analogy between a city and a cell, wastewater would be more likely a part of exocytosis.
Exocytosis is the process of expelling material from the cell into the extracellular fluid.
Just like a city disposes of its waste by releasing it into the environment, a cell can release waste material through exocytosis by fusing a membrane containing the waste material with the cell's plasma membrane.
