Question

1. there are no membrane-bound organelles inside ____, means that there will not be any ____ found inside of them. options: eukaryotes; nucleus, eukaryotes; ribosomes, prokaryotes; mitochondria, prokaryotes; ribosomes

Explanation:

To solve this, we recall the differences between prokaryotes and eukaryotes. Prokaryotes lack membrane - bound organelles, while eukaryotes have them. Mitochondria are membrane - bound organelles. Eukaryotes have a nucleus (membrane - bound) and ribosomes (non - membrane - bound). Prokaryotes have ribosomes (non - membrane - bound) but no mitochondria (membrane - bound). So we analyze each option:

• Option 1: Eukaryotes have a nucleus (membrane - bound), so this is wrong.
• Option 2: Eukaryotes have ribosomes (non - membrane - bound), but the first part is wrong as eukaryotes have membrane - bound organelles.
• Option 3: Prokaryotes lack membrane - bound organelles, so they don't have mitochondria (a membrane - bound organelle). This fits.
• Option 4: Prokaryotes do have ribosomes (non - membrane - bound), so this is wrong.

Answer:

C. prokaryotes; mitochondria
