<span>Light energy has to be converted into chemical energy in ATP molecules. Plants change light into sugar molecules and both plants and animals change sugar into ATP molecules, which allows for our survival</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.
The answer is c as the population had failed to survive
