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.
A is the correct answer!
- water can moderate temperature v. well that's why it's used as a cooling agent
- water expands upon freezing (that's why ice floats on water!)
Both auxin and cytokinin are used to increase size of stem and fruits
