Answer:
Schistosomiasis is a disease caused by infection with blood flukes of the geneticist Schistosomiasis. Transmission of, and exposure to, the parasite result from fecal or urinary contamination of freshwater containing intermediate host, snails, and dermal contact with the same water.
Explanation:
Snails can carry diseases such as angiostrongyliasis, clonorchiasis, fascioliasis, fasciolopsiasis, opisthorchiasis, paragonimiasis, and schistosomiasis. Be cautious when stepping into freshwater, because there may be snails in it. I recommend not picking up or touching snails. 
 
        
             
        
        
        
Answer: The correct answer is option b.
Explanation:
RNA viruses have RNA as genetic material whereas the host cells usually have DNA as genetic material.
So, in order to integrate its genome with host DNA, the virus must form DNA from RNA, that is, reverse transcription.
It is the process by which DNA is formed using RNA as a template strand.
However, reverse transcriptase (enzyme which catalyzes reverse transcription) is usually not present in host cells. 
Thus, RNA viruses carry their own set of enzymes which help in the replication of viral genome and its recombination with host DNA as host cells lack these enzymes.
