Nuclear membrane
Prokaryotic cells lack membrane-bound organelles and well-organized nucleus. The nuclear membrane is absent in a prokaryotic cell. The nuclear membrane is a double membrane layer which surrounds the nucleus. It is made up of lipids, that encases the genetic material.
Hence, the correct answer is 'Nuclear membrane'.

<span>When you put the cells in a salt solution you are placing the cells into a hypertonic solution. That means the solute concentration outside the cell is higher than the solute concentration inside the cell. You should know from your own studies that water will move from areas of high water concentration to areas of low water concentration. A hight solute concentration means there is low water concentration. That means that the water will move from the onion cell and out into the hypertonic solution and the onion cell will shrivel up.</span>

<span>Archaebacteria are the oldest living organisms on earth. They are prokaryotes and unicellular. Archaebacteria are found in very harsh conditions (such as at the bottom of the sea or in volcanic vents). This is thought to be because the early Earth’s atmosphere was filled with poisonous gases and was very hot – nothing could survive, except the archaebacteria. These slowly gave way to modern organisms when the Earth’s conditions settled down and oxygen was introduced to the atmosphere. " </span>
Volatile Liquids
They evaporate quickly because they tend to have weak inter molecular forces.
