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:
Biogeography, the study of the geographical distribution of organisms, provides information about how and when species may have evolved. Fossils provide evidence of long-term evolutionary changes, documenting the past existence of species that are now extinct.
To give one classic example, the forelimbs of whales, humans, and birds look quite different on the outside. That's because they're adapted to function in different environments. However, if you look at the bone structure of the forelimbs, you'll find that the organization of the bones is remarkably similar across species. It's unlikely that such similar structures would have evolved independently in each species, and more likely that the basic layout of bones was already present in a common ancestor of whales, humans, and birds.
No, it does not, because the octet rule says that an atom needs to have eight electrons in its valence shell to be stable. The exceptions are hydrogen and helium, which need only two electrons. This atom has only one electron.
The appropriate response is tundra, taiga, steppes. Tundra is a sort of biome where the tree development is obstructed by low temperatures and short developing seasons. The term tundra comes through Russian тундра from the Kildin Sami word tūndâr "uplands", "treeless mountain tract"
