Answer:
What do they look like?
Glaciers look like solid blocks of ice.
What climate do they exist in?
Regions that have high snowfall in winter and cool temperatures in summer.
Where can you find them?
Most of the world's glacial ice is found in Antarctica and Greenland, but glaciers are found on nearly every continent, even Africa.
What do you think we can learn from glaciers?
Glaciers preserve bits of atmosphere from thousands of years ago in these tiny air bubbles, or, deeper within the core, trapped within the ice itself. This is one way scientists know that there have been several Ice Ages. Scientists are also finding that glaciers reveal clues about global warming.
(The last question is unclear to me, so I'm going to take a guess as to what you meant)
Why is sea ice so important?
Arctic sea ice keeps the polar regions cool and helps moderate global climate.

Answer:
Lysine
Explanation:
lysine residues on the histone tails of the octamer cn be activated by both acetylation and methylation patterns to influence accessibility or silencing of the genes respectiviely. for example, acetylation of H3K27 (histone 3 lysine residue 27) brings about a region of active chromatin allowing access to transcription activity while its trimethylation will cause silencing of the associated gene at that particular area (no expression of that gene)
