<span>Natural selection is likely when there are stronger selection pressures. For example, a perpetual selection pressure is the fact that organisms have to compete for food and resources, meaning the best adapted ones survive. However, a stronger selection pressure may cause natural selection to occur more obviously. An example of this is when the number of white peppered moths decreased during industrialization in England due to the soot collecting on the trees. The change in population was very fast and obvious.</span>

Jack was sick with a cold and fever. the doctor prescribed him erythromycin, an antibiotic. analyzing the process of translation
KatRina [158]

Answer:

This is because it is a selective antibiotic that, when entering the body, binds to the 50s subunit of bacterial ribosomes, thus causing the disruption of protein transcription of bacteria.

This drug does not stop the transcription of human proteins since bacteria and humans do not have the same ribosomes, therefore, humans or sick cells do not have the active site to which the drug binds.

Explanation:

This is because it is a selective antibiotic that, when entering the body, binds to the 50s subunit of bacterial ribosomes, thus causing the disruption of protein transcription of bacteria.

This drug does not stop the transcription of human proteins since bacteria and humans do not have the same ribosomes, therefore humans or host cells do not have the active site to which the drug binds.

Erythromycin falls into the macrolide family and is considered a drug that is bacteriostatic at low concentrations and bactericidal at very high concentrations.

The difference between these named terms is that one ends the life of the bacterium (bactericidal) and the other stops the bacterial metabolism preventing its possibility of increasing in number.
