Answer:
RNA interference
Explanation:
Interference RNA is a mechanism of post-transcriptional silencing of specific genes, so that small RNA molecules complementary to an mRNA lead to its degradation, thus preventing its translation into proteins.
Gene silencing by interfering RNA is induced by small double stranded RNA molecules of 21 to 27 nucleotides called siRNA. These siRNAs undergo a series of processes in the cell as a result of which their double stranded RNA unfolds in a sense strand and an antisense strand. The antisense strand binds to the mRNA chain specifically for base complementarity, causing the resulting complex to be recognized by cellular and degraded mechanisms. Each siRNA is highly specific for the target nucleotide sequence to which it degrades. This phenomenon of gene interference occurs naturally in the body, being involved in the development and defense against viruses.

Answer:
mitochondria and chloroplasts
Explanation:
the theory says that the bacteria which used oxygen and changed it to ATP molecules changed into mitochondria and those that used light energy to manufacture their own food changed into chloroplasts.this happened after the small prokaryotes which were bacteria were engulfed by the bigger prokaryotes of which some managed to survive and lived together through symbiosis hence the evolution to mitochondria and chloroplasts creating a eukaryotic cell.
I believe the highest occupied electron energy sub level for carbon would be the 2p sub level, in the second energy level.
C = 1s^2 2s^2 2p^2.
