Answer:
Taking antibiotics only on doctor prescription and completing the full course of antibiotics.
Explanation:
Antibiotic resistance occurs when bacteria do not get harmed or killed by a drug which is made against them. Misuse and overuse of antibiotics are the main culprits which induce antibiotic resistance in bacteria.
To prevent the spreading of antibiotic-resistant bacteria antibiotics should only be taken on doctor's prescription. Full course of antibiotics should be done to eliminate all the bacteria which ensures that no bacteria is left to gain antibiotic resistance against the drug.
Antibiotics do not affect or kill virus therefore they should not be taken in viral infection.
C. ferns.
Explanation:
The ferns are ancient plants that have managed to survive until the present. They are not closely related to the dominant plants nowadays, the flowering plants, but instead they are closely related with plants that have gone extinct tens and hundreds of millions years ago. Even though the ferns are not the dominant plants, they have managed to find a niche and firmly hold onto it, so they remained widespread, normally occupying the lower layers of the forests.
Unlike the flowering plants that produce flowers and then seeds in order to reproduce, that is not the case with the ferns. The ferns actually reproduce through spores, being widely dispersed by the wind and managing to spread out and reproduce over relatively large territory very quickly.
Answer:
Something studied on the molecular level is the water.
Explanation:
Water is a molecule formed by two hydrogen atoms and one oxygen atom, whose chemical representation is H₂O. It is a molecule whose polarity makes it a universal solvent of other polar molecules.
The molecular level corresponds to the level of organization where two or more atoms unite to form molecules or substances, united by chemical bonds. H₂O is studied at this level due to its chemical structure.
With respect to other options:
- <u><em>Hydrogen and oxygen</em></u><em> are atoms, and correspond to the level of atomic organization.</em>
- <u><em>Protons</em></u><em> are particles that are part of an atom, and correspond to the subatomic level.</em>
