The mutation was most likely the result of a change in the ability of the DNA replication.
<h3>How mutation occur?</h3>
Mutations result either from errors that occurs in DNA replication or caused by the mutagens, such as chemicals and radiation, which react with DNA and change the structures of individual nucleotides so we can conclude that the mutation was most likely the result of a change in the ability of the DNA replication.

Given what we know, we can confirm that the fact that Mannitol salt agar can determine which species of Staphylococcus is present makes it an example of a selective differential medium.
<h3>What is a selective differential medium?</h3>
- This type of medium is very similar to that of a differential medium in that it also allows more than one type of microbe to grow.
- It also allows the user to continue to distinguish between the microbe colonies based on biochemical differences.
- However, in contrast to that of a basic differential medium, this differential medium is also selective in that it controls which type of microbe specifically is allowed to grow.
Therefore, we can confirm that since Mannitol salt agar can determine which species of Staphylococcus is present, it can be considered a differential selective medium because it allows multiple microbes to grow while controlling which types are allowed to grow.

Answer:
climatologists
Explanation:
they are the ones studying the effects of global warming on earth's climate
Answer:
Please find the explanation below
Explanation:
Our nucleus is made up of a genetic material called deoxyribonucleic acid (DNA), which is a double-helical structure that stores the genetic information needed for the optimal functioning of any organism. DNA, alongside RNA are nucleic acids that are composed of NUCLEOTIDES subunits. The nucleotide consists of a pentose sugar (deoxyribose in DNA and ribose in RNA), nitrogenous base and a phosphate group.
However, the genetic information stored in the DNA molecule needs to be expressed in order to form useful products (proteins). This genetic expression is done in two stages viz: transcription and translation. Transcription, which is catalyzed by an enzyme called RNA polymerase is the process whereby the information stored in the DNA is used to synthesize a mRNA molecule. However, this mRNA molecule is considered pre-mature until it is processed. RNA processing occurs in three stages viz: 5' capping, polyadenylation, and splicing.
5' capping involves adding a 5' cap to the marks molecule. Polyadenylation involves adding a poly(A) tail to the mRNA molecule while splicing is the removal of introns (non coding regions) with the aid of Spliceosomes and joining of the exons (coding region). After processing, the mRNA becomes matured and ready to be translated.
Translation is the process whereby the mRNA transcript is used to synthesize a protein molecule. It occurs in the ribosomes (organelles for protein synthesis, a complex of rRNA and proteins) where the mRNA is read in a group of three nucleotides called CODON. The reading is done by the Anticodon of a transfer RNA (tRNA), which is complementary to the codon.
Translation occurs in three stages: initiation, elongation and termination. The mRNA attaches to the P site of the ribosomes (initiation) where it is attached to by a tRNA's anticodon complementary to it. The anticodon carries the amino acid corresponding the codon and shifts to the A-site. The addition of amino acid to the polypeptide chain continues (elongation) until a stop codon is encountered, which signals the end of the translation process i.e. termination. This causes the polypeptide (protein) to be released from the E-site.
The synthesized protein undergoes packaging and modification in the Golgi apparatus.
