b. small rings of bacterial DNA
Evoultion is the change of the allele frequencies and the inherited traits of a population over time.
The idea of evolution is that the species change over time. The proposed mechanism of evolution is natural selection. Natural selection favors inheritable trait, suitable for survival and reproduction. Organisms with such traits will tend to leave more offspring than others, and thus will evolve over time.
Answer:
1- the bacteriostatic effect refers to the fact that they stop the metabolism of pathogenic bacteria, which means that they do not reproduce, do not colonize and do not generate the disease.
Bacteria in order to trigger a pathogenic response need to comply with their metabolism and this does not happen in the bacteriostatic effect.
2- Broad spectrum antibiotics where the patient's life is at risk, difficulty swallowing or breathing, and in infections that involve many planes or we are facing an extremely complex buofilm.
Low-spectrum antibiotic, in mild, focal infectious diseases that do not compromise the systemic factor and are suspected of simple or little complex pathogens.
3-Through mechanisms and virulence factors that are transmitted between them. One mechanism is sporulation, the change of essential metabolite, among others.
4- Prevents the spread and resistance because it reduces the bacterial load of pathogenic bacteria that in the future could form bacteruphages.
Explanation:
Broad spectrum antibiotics cover many bacteria, that is, they kill many bacteria of different families and even characteristics, while low spectrum antibiotics are the opposite.
Answer:
Homeostasis is the tendency to resist change in order to maintain a stable, relatively constant internal environment. Homeostasis typically involves negative feedback loops that counteract changes of various properties from their target values, known as set points
