The image depicts a chemical reaction involving a cyclohexane-derived structure. 

### Top Diagram:
- **Structure**: 
  - A cyclohexane ring with a single bond extending from one carbon atom, forming a secondary carbon attached to a leaving group.
  - The leaving group is depicted as \(^+\text{O}^\times\), indicating it is positively charged and likely an oxonium ion. 
  - A bromide ion (\(\text{Br}^-\)) is free in the environment, likely positioned for a nucleophilic attack.
- **Hydrogens**: Two hydrogen atoms are shown attached to the secondary carbon.
- **Instructions**: "Select to Add Arrows" suggests the addition of curved arrows to show the movement of electrons resulting in the reaction mechanism.

### Bottom Diagram:
- **Structure**: 
  - The final cyclohexane structure after the reaction.
  - A bromine atom is now bonded to the secondary carbon that previously bore the oxonium.

### Explanation:
The top diagram likely represents the initial state where the oxonium is the leaving group, and the bromide ion is ready to attack. The lower structure shows the product, where the bromide ion has replaced the oxonium ion, forming a new C-Br bond and completing the substitution reaction.

Curved arrows are used to illustrate the flow of electrons. Using the provided starting and product structures, draw the curved electron-pushing arrows for the following reaction or mechanistic steps.

Be sure to account for all bond-breaking and bond-making steps.

**Diagram Explanation:**

1. **First Structure (Top):**
   - A cyclohexane ring with a methyl group attached.
   - A hydrogen bromide (H-Br) molecule, with the Br atom shown as partially negative (\(\delta^-\)).

2. **Second Structure (Bottom):**
   - A cyclohexane ring with a carbocation (\(C^+\)) indicating a positive charge at the carbon previously bonded to the methyl group.
   - Hydrogen (\(H\)) atom bonded to this carbon.
   - Bromide ion (\(:Br^-\)) shown separately, indicating it has left.

**Instructions:**
- The user is prompted to "Select to Add Arrows" to illustrate electron movement, likely indicating drawing steps such as the breaking of bonds in H-Br, the formation of the carbocation, and the release of the bromide ion.
