Aneli [31]

Answer:

Transcription, mRNA (processing, transport, localization and stability), translation.

Explanation:

  • Transcription is regulated in two levels, though chromatin regulation (methylation and acetylation) to loose or increase histone's affinity to DNA and through cis and trans elements such as promoters, enhancers, and silencers (cis) to active/deactivate and RNA polymerase and transcription factors and co-factors (trans).
  • mRNA can be regulated using poly-A tails or 5'-caps to shorten or give them more time before they degrade, it could also be spliced to eliminate introns.
  • In the translation stage, the regulation occurs during the initiation through a scanning procedure that ensures the 40s ribosomal subunit bind correctly to the untranslated portion of RNA

explain how the rate at which fossil fuels are transferred into the atmosphere, as shown in the diagram, has altered the carbon
oee [108]

Answer:

Explanation:

Over the past 250 year or two and a half centuries fossil fuels have been burnt at a very fast rate to meet the various human needs. These fossil fuels contains huge amount of carbon dioxide. And when these fossil fuels are burnt in power factories, power plants, cars etc. carbon moves from the fossil to the atmosphere. And since carbon dioxide is a greenhouse gas it traps more heat and hence there is a global temperature rise.

It is estimated that every year almost five and a half billion tons of carbon is released by burning fossil fuels. And since this amount of carbon dioxide is very huge for plants to convert all of them into oxygen via photosynthesis it leads to disbalancing in the carbon cycle that is more carbon dioxide is produced than the amount can be utilized which finally leads to rise in Earth's temperature as all of the extra carbondioxide ends up in Trapping more sun light.
