Polar ice cap in Antarctica.
Explanation:
Scientist drill ice cores from inside the polar ice cap in Antarctica to study variability of climate and differentiate that variability From global climate change. Each layer of the ice tells about weather and what the Earth was like when the first snow fell.
For example, Le grande says that as snow deposits into a growing glacier, the temperature of the air imprints on water molecules.
Icy layers hold particles,aerosols, sea salts, trace elements that were in the atmosphere before and they abide for thousands of years and provide evidence of past events.
Archaea differ from bacteria in that archaea lack peptidoglycan.
<h3>
What about archaea and bacteria?</h3>
- Although archaea lack internal membranes, they do have a cell wall and swim by using flagella.
- The difference between bacteria and archaea is that bacteria have an ester-linked cell membrane, while archaea have an ether-linked cell membrane.
- Organelles and other internal membrane-bound structures are not present in the cells of bacteria and archaea.
- In contrast to eukaryotes, bacteria and archaea do not have a nucleus that separates their genetic material from the rest of the cell.
- Similar to Eubacteria, Archaea have a polysaccharide and glycoconjugate-rich cell wall.
- The strong cell borders that archaea form despite not having peptidoglycan make them resistant to high internal osmotic pressure.
