To determine which domains contain only one body type, we will carefully analyze the given table.
Here are the characteristics for each domain and kingdom from the table:
1. Bacteria
- Kingdom: Eubacteria
- Body type: Unicellular
2. Archaea
- Kingdom: Archaebacteria
- Body type: Unicellular
3. Eukarya
- Kingdoms:
- Protista: Most unicellular
- Fungi: Both (unicellular and multicellular)
- Plantae: Multicellular
- Animalia: Multicellular
We need to identify the domains that have kingdoms with only one body type across all kingdoms listed under them.
Upon examining the table:
- The Bacteria domain has kingdoms that are only unicellular.
- The Archaea domain has kingdoms that are only unicellular.
- The Eukarya domain has kingdoms with varied body types, including unicellular, multicellular, and both.
From this analysis, we observe that:
- Bacteria only includes unicellular organisms.
- Archaea only includes unicellular organisms.
- Eukarya includes a mix of unicellular, multicellular, and both types.
Therefore, the correct domains that contain only one body type (either entirely unicellular or entirely multicellular) are:
Bacteria (unicellular) and Archaea (unicellular).
So the correct choice is:
Bacteria and Archaea.
