The prokaryotes have both 70s and 80S ribosomes.

Answer

### Step-by-Step Solution:

1. **Understanding Ribosome Types**:
- Ribosomes are cellular structures responsible for protein synthesis. They are classified based on their sedimentation rate, measured in Svedberg units (S).
- Prokaryotes have ribosomes that are classified as 70S, while eukaryotes have ribosomes classified as 80S.

2. **Identifying the Composition of Ribosomes**:
- The 70S ribosome in prokaryotes is composed of two subunits: a larger 50S subunit and a smaller 30S subunit.
- The 80S ribosome in eukaryotes is composed of a larger 60S subunit and a smaller 40S subunit.

3. **Clarifying the Statement**:
- The statement in the question claims that prokaryotes have both 70S and 80S ribosomes. This is incorrect.
- Prokaryotes exclusively have 70S ribosomes, while eukaryotes possess 80S ribosomes.

4. **Conclusion**:
- Therefore, the statement that "the prokaryotes have both 70S and 80S ribosomes" is false. Prokaryotes only have 70S ribosomes.
