Which of the following are characteristics of archaeal cell membranes that probably help them survive at very high temperatures?
torisob [31]

Answer:

Option-B, C and E

Explanation:

Archaebacteria are a group of prokaryotes which can survive the extreme conditions. The archaebacteria which can survive very high temperature are called hyperthermophiles. The hyperthermophilic bacteria can survive temperature range between 70 t 125 °C observed in hydrothermal vents.

The archaea bacteria can withstand the high temperature as their membrane is adaptive. The membrane of the archaea is more stable due to the ether linkage which makes carbon less chemically reactive. The phospholipids possess a monolayer which decreases the layer fluidity and thus the unwanted movement of molecules.

The archaea also contain cyclopentane rings in the ester-linked phospholipids which allows tight pacing of the molecules which decrease the movement of solute into and out of the cell.

Thus, the selected options are correct.

Select the kingdoms where all prokaryotes are classified.
grigory [225]

Answer:

Archaea

Eubacteria

Explanation:

Both the kingdoms archaea and eubacteria comprise of prokaryotes yet there are some differences present between the two kingdoms.

The archaea have a distinct evolutionary history as compared to the eubacteria. The cell wall of archaea is made up of Pseudo-peptidoglycan where as the cell wall of eubacteria is made up of peptidoglycan or lipopolysaccharide. Interior membranes cannot be found in the archaea but are present in the eubacteria.
