Answer:
Antibiotics inhibit enzymes specific to bacteria and have no effect on virally encoded enzymes
Explanation:
The specificity of the antibiotics to inhibits some bacterial enzymes is one of the major reasons why antibiotic do not affect viruses.In addition antibiotics are designed to have a significant destructive effects on the mechanisms of biochemical reactions in bacteria and its physiology, e,g on the cells walls,( inhibiting the formation of peptydoglycans) on certain organelles e,g ribisomes (inhibiting protein synthesis) and on the DNA(disrupting replication). The virus physiology is different from bacteria, therefore the design of antibiotics will nor affect these same mechanisms in viruses, thus no specificity for the antibiotic to act on in virus
Answer:
B
Explanation:
Convection occurs to divert heat generated by the core and spread through the mantle. at the bottom of the mantle, heat is gained, causing the mantle to be less dense and rise up. at the top, heat is subsequently lost, resulting in am increase of mass and a drop down for the mantle. this process repeats indefinitely
The cliellum is located on the anterior end of the earthworm. The anterior end of the earthworm is used in mating, and the mouth and brain are also located in the anterior end.
