The answer is applying sustainable development.
The trend of declining ecosystem resource availability and increasing demand for these resources can best be countered by applying sustainable development. Sustainable development refers to the development in which the needs in the present is meet without compromising the future generation's ability to meet their own needs.
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.
Kingdoms are classified into three Domains and into one of the six kingdoms of life.
Answer:
Nucleic acids are the most important macromolecules for the continuity of life. They carry the genetic blueprint of a cell and carry instructions for the functioning of the cell.
