Accepted Answer

### Part 1: Filling the Character Matrix (Completed as per Traits)
The given matrix already has some traits marked. Let's confirm or fill (if needed) based on organism characteristics:

| Organism       | Cells | Legs | Antenna | Wings | 2 sets of wings |
|----------------|-------|------|---------|-------|-----------------|
| Worm           | x     |      |         |       |                 |
| Spider         | x     | x    |         |       |                 |
| Carpenter Ant  | x     | x    | x       |       |                 |
| House fly      | x     | x    |         | x     | x               |
| Dragonfly      | x     | x    |         | x     | x               |

### Part 2: Creating the Cladogram
A cladogram groups organisms by shared derived traits. We analyze the traits (from most general to most specific):

1. **Common Ancestor (All Organisms)**: All have *Cells* (most basic trait).
2. **Trait: Legs**: Separates Worm (no legs) from Spider, Carpenter Ant, House fly, Dragonfly (have legs).
3. **Trait: Antenna**: Separates Carpenter Ant (has antenna) from Spider, House fly, Dragonfly (no antenna).
4. **Trait: Wings**: Separates Spider, Carpenter Ant (no wings) from House fly, Dragonfly (have wings).
5. **Trait: 2 sets of wings**: Both House fly and Dragonfly have this, so they share a more recent common ancestor than with Spider/Carpenter Ant.

### Final Answer (Cladogram Summary)
The cladogram starts with a common ancestor (all have cells). It splits into Worm (no legs) and a group with legs. The leg - group splits into Spider (no antenna, no wings), Carpenter Ant (antenna, no wings), and a wing - group (House fly, Dragonfly, both with 2 sets of wings).

(For a visual cladogram, draw a tree with branches:
- Root: Common Ancestor (Cells).
- Branch 1: Worm.
- Branch 2: Spider, Carpenter Ant, House fly, Dragonfly (Legs).
  - Sub - branch: Spider.
  - Sub - branch: Carpenter Ant (Antenna).
  - Sub - branch: House fly, Dragonfly (Wings, 2 sets of wings).)
