The correct answer is D. Without capsids, viruses could not replicate
Explanation:
A viral infection is caused as a virus enters the body and this replicates inside it by using the host's cells. This is possible through the capsid which is an external layer in the virus that provides protection to it and helps the virus replicate because the capsid is essential for the virus to attach and penetrate the host's cells to replicate. According to this, if a drug damages the capsids the virus could not replicate and this should or reduce the infection caused by the virus. Thus, a drug that damages capsids helps treat a viral infection because "without capsids, viruses could not replicate".
Antibiotics are ineffective against viruses because viruses do not have cells. Viruses are infectious agents that live within the cells of other living things. Antibiotics work by breaking down the cell walls of bacteria or interfering with the bacteria's ability to repair its cell's DNA, according to How Stuff Works.
The difference between a hot spot volcano and the volcanoes from Ring of Fire can mainly be seen in the way of formation and functioning. The hot spot volcanoes are far away from any tectonic plate boundary and they manage to penetrate the crust over them and come out on the surface to usually create volcanic islands. The activity of the volcanoes from the Ring of Fire depends directly from the activity between the bordering tectonic plates, and as the borders move over time, the volcanoes stop existing, and new ones rise in the direction where the boundary moves.
The similarity can be seen in the type of eruptions, and that usually both types of volcanoes form volcanic islands.
Example for a hot spot volcano is Mauna Loa on Hawaii.
Answer : cathode, protocathode
During an electrochemical reaction, electrons move through the external wire toward the cathode and positive ions in the salt bridge move toward the protocathode.
