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.

Answer:
ATP and NADPH are used to energy for the production of the Calvin cycle. Once their energy is released, they revert back to ADP and NADP+ and can be reused again.
Explanation:
ATP and NADPH are energy carriers that can be used to power chemical reactions. Once they have energized cellular processes, they become their 'low energy' form of ADP and NADP+. Later, they can reform ATP and NADPH to power more reactions
The orca, or killer whale, for example, is actually the largest member of the dolphin family. Dolphins are by far more prevalent than porpoises. Most scientists agree that there are 32 dolphin species (plus five closely related species of river dolphin) and only six porpoise species.
