Answer:
Volcanic eruptions help provide fertile soils (Option A)
Explanation:
There have been numerous confirmation of the existence of fertile lands around regions known to have experienced volcanic activities. The regions around Mount Vesuvius is not an exception even though volcanic activities around the region are over thousands of years ago.
This is because, when Volcano occurred in such regions, it deposited volcanic materials rich in minerals. The materials are then weathered or broken down by the action of water or erosion to release nutrients into the soil.
Answer:
c. selective toxicity takes advantage of structural and/or metabolic differences between host and pathogen
Explanation:
Selective toxicity is the mechanism by which antibiotics work. They cause damage to the pathogen but do not harm the host. Hence, they are selectively toxic in their mechanism. They can target both the structural or the metabolic differences between host and pathogen. Many antibiotics target unique sites in the pathogen's structure or the sites which might be present in host cells too but are not essential for the survival of the host. An example of structural difference being targeted by antibiotics is the enzymes which synthesis the bacterial cell wall so that the cell wall is disrupted. A metabolic difference being targeted would be the mechanism by which bacteria replicates so that host cell replication process is not hindered.
