Answer:
Vaccinations
Explanation:
For example, if a disease has an R0 of 18, a person who has the disease will transmit it to an average of 18 other people. That replication will continue if no one has been vaccinated against the disease or is already immune to it in their community. So if you have (for example) a vaccination then you're less likely to get it, resulting in a lower R0

Question 3 you could say that…
The closer you are to the equator (30N-30S) the more solar radiation present. This leads to, less clouds appearing in them areas and the climate bring quite hot.
Answer:
At the "Elongation" or "middle stage" of the translation, the peptide bond is formed.
Explanation:
We know that there are three steps or stages of the translation process. Among these 3, in the elongation stage, amino acids are carried to the ribosome by tRNAs, and then they become linked together to form a chain.
In this stage, at first, methionine-carrying tRNA starts in the middle slot of the ribosome, called the P site. Next to it, a new codon is opened in another slot, called the A site. The A site will be used for the "landing site" for the next tRNA. Once the matching tRNA has arrived in the A site, the formation of the peptide bond happens. This peptide bond connects one amino acid to another. This step transfers the methionine from the first tRNA onto the amino acid of the second tRNA in the A site.
Answer: mRNA moves through pores in the nuclear membrane
Explanation: nuclear membrane pores permit the passage of mRNA, but only after processing within the nucleus. The non-coding parts of the RNA are deleted (introns), the 5’ end capped to prevent premature degradation, and a string of A nucleotides added at the 3’ end (improves stability).
