Question 2 please help choices are prokaryote or eukaryote

1. Circular chromosome, no mitosis = PROKARYOTES

2. Sterols in membrane, performs exocytosis = EUKARYOTES

3. Cell wall and mitochondria present = EUKARYOTES

4. Spirillum shape present = PROKARYOTES

Explanation:

Prokaryotes are organisms that notably lack a membrane bound nucleus while eukaryotes possess a membrane bound nucleus. Although, there exists other characteristics and features that distinguishes these two domains of organisms.

- Circular chromosome is a feature possessed by prokaryotic organisms e.g. bacteria. Also they do not undergo mitosis, instead they perform binary fission.

- Sterols are a class of lipids present in the membranes of all eukaryotes. Prokaryotes lack this feature. Also, eukaryotes perform the process of exocytosis, which is how eukaryotic cells release waste particles outside the cell.

- Mitochondria is a structure present only in eukaryotic organisms. Hence, an organism that possesses both cell wall and mitochondria is an EUKARYOTE.

- Spirillum is a characteristics of spiral shaped bacteria called spirochetes. Since bacteria are prokaryotic, hence, the spirillum shape is a prokaryote.
