Are their any choices for this or is this a written response?
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.
Water is a liquid and it’s molecules are far apart and move pretty freely and ice is a solid so it’s molecules are packed in tightly and they don’t move.
The right option is c. usually is caused by consuming
improperly home-canned food.
Botulism is a severe food borne illness
caused by the bacteria clostridium botulinum. This illness is caused by eating foods
contaminated with the bacteria or its toxin. Ingestion of foods that are not canned
properly at home is the major cause. Symptoms of botulism generally appear 12
to 72 hours after eating contaminated food.
