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.

Using a microscope

Explanation:

A microscope is a scientific device used for magnifying and studying very tiny features.

  • A unicellular organism is an organism made up of a single cell.
  • A multi-cellular organism is made up of several cells.
  • A cell is a very small microscopic structure.
  • It is usually described as the fundamental unit of life.
  • Due to its small size, the naked eyes cannot see it
  • The invention of the microscope opened up the world of cells.
  • Since they have been around for a long time, distinction of cells would have been made possible at those times using a microscope.
