Why are unicellular organisms different from multicellular organisms in how they are organized and what they do?
Unicellular organisms are simple because they have only one cell, while multicellular organisms are more complex because they have more cells.
Unicellular organisms are simpler because a single cell does all the jobs, whereas in multicellular organisms, the tasks are divided among different cells.
Unicellular organisms are bigger in size, while multicellular organisms are made up of many smaller cells.
Unicellular organisms are inefficient at using resources, while multicellular organisms are better at organizing tasks among specialized cells to use resources efficiently.
Why it is easier for prokaryotic cells to become infected with some viruses compared to eukaryotic cells?
The cell wall in eukaryotic cells is a less effective barrier.
Prokaryotic cells have less DNA than eukaryotic cells.
Prokaryotic cells lack a nucleus, unlike eukaryotic cells.
The rapid growth of prokaryotic cells results in increased virus replication.
You are investigating the differences between animal and plant cells. You have observed 2 cells, Cell X and Cell Y, under a microscope.

Cell X is an animal cell and Cell Y is a plant cell.
Cell X is a plant cell, and cell Y is an animal cell.
Both Cell X and Cell Y are animal cells.
Both Cell X and Cell Y are plant cells.
