Let's start by examining the given table of symbols and the corresponding components in an electric circuit:
[tex]\[
\begin{array}{|c|c|}
\hline
\text{Symbol} & \text{Component} \\
\hline
Q & \\
\hline
-1 / 1- & \\
\hline
-\sigma \circ & \\
\hline
\sim & \\
\hline
\end{array}
\][/tex]
We need to determine the appropriate label for each symbol based on the standard symbols used in electrical diagrams.
### Matching Symbols to Components
1. Understanding the Symbols:
- \( Q \): This symbol is often used to represent a battery in circuit diagrams.
- \( -1 / 1- \): This pattern resembles a switch symbol, where the '1' and '-1' are indicative of the open and closed states of a switch.
- \( -\sigma \circ \): The combination of a line with a sigma (σ) and a circle is a traditional representation of a resistor.
- \( \sim \): This is generally used to indicate an alternating component like a bulb or an AC power source but is commonly recognized for bulbs in simple circuits.
2. Identifying the Marked Cell:
- The problem specifically highlights the marked cell with the symbol \( -\sigma \circ \).
### Conclusion
Given the standard meanings of these symbols in an electric circuit:
- \( -\sigma \circ \) is the symbol for a Resistor.
### Final Labeled Table
[tex]\[
\begin{array}{|c|c|}
\hline
\text{Symbol} & \text{Component} \\
\hline
Q & \text{Battery} \\
\hline
-1 / 1- & \text{Switch} \\
\hline
-\sigma \circ & \text{Resistor} \\
\hline
\sim & \text{Bulb} \\
\hline
\end{array}

So, the label that Patty should place in the marked cell corresponding to the symbol \( -\sigma \circ \) is:
Resistor.
