RNAi is a mechanism involved in gene silencing, the process that turns on and off genes. To do that, it is triggered by double-stranded RNA (dsRNA).
The enzyme "dicer" cuts dsRNA into smaller fragments called (a) small interfering RNA. Once these fragments are cleaved, they bind to argonaut proteins and activate the RNA-induced silencing complex (RISC). This complex targets and degrades (a) specific messenger RNA (mRNA). By degrading the mRNA, this process interrupts the gene expression.

Answer:
Jet streams are like rivers of wind high above in the atmosphere. These slim strips of strong winds have a huge influence on climate, as they can push air masses around and affect weather patterns. ... Temperature also influences the velocity of the jet stream
Explanation:
A possible answer could be parasympathetic.
The parasympathetic nervous system is the nervous system is characterised by things such as mentioned above "slower respiration and heart rate" because it is the system that responds to stimulation, which can occur during eating, digestion, defecation, etc.
It is also reponsible for well known reaction such as "flight-or-fight" and other similar ones.
