d contain a cell wall
e has membranous organelles
10 p

Explanation:

Question 5

Archaea and eukaryotes share some molecular features, such as similar RNA polymerase structures and histone - like proteins (in some archaea). DNA studies have shown these similarities. Cyanobacteria, common bacteria (e.g., E. coli) are prokaryotes with different molecular characteristics compared to archaea.

Prokaryotic organisms are generally smaller than eukaryotes, lack a nucleus (their DNA is in the nucleoid region), and usually have one circular chromosome. Many prokaryotes (e.g., bacteria) have cell walls. However, prokaryotes do not have membrane - bound organelles. Membranous organelles (such as mitochondria, endoplasmic reticulum) are a characteristic of eukaryotic cells.

Answer:

C. eukaryotes
