So, all the continents can combine into a supercontinent we call Pangea. We believe Pangea was formed a long time ago. Because of different world events (earthquakes, fissures,ice melting, the meteor that hit the dinosaurs, etc)this supercontinent split and the continents drifted away eventually forming the modern day topography we know today. We have evidence that Pangea was formed a long time ago because of similar species on different continents that would be too far away to share a common ancestor otherwise. (think about birds being on every continent, they can't have flown all the way across the Atlantic/Pacific)
<span> Photosynthesis and cellular respiration are two major processes of carbon cycling in living organisms. A.) Both occur in animal and plant cells, Both include reactions that transform energy. 3) Both convert light energy into chemical energy.</span>
Answer:
Change in chromatin structure-------Acetylation of histones facilitates transcription
Activity of transcription apparatus------Transcriptional activators increase promoter activity by interacting with the RNAPII holoenzyme
RNA processing---------Alternative splicing produces different transcripts from the same gene.
RNA interference-------A siRNA and the transcript it targets is transcribed from the same gene.
Initiation of translation-------Limited availability of initiation factors prevents translation of mRNA.
