Question

circle true or false for the following statements. true or false vaccines are a solution containing weakened or killed viruses. true or false viruses can replicate on their own. true or false vaccines help the body to create antibodies against a virus. true or false there is a vaccine for every single virus. true or false you have to get some vaccines every year (like the flu shot). true or false not only can viruses take over the host cells dna or rna, but viruses can \hijack\ the cells metabolism. true or false viruses can utilize enzymes to take over a cells machinery

Explanation:

1. Vaccines are solutions with weakened or killed viruses to trigger an immune - response, so the first statement is True.
2. Viruses replicate using their own genetic material but rely on host - cell machinery, so the second statement is True.
3. Vaccines help the body produce antibodies against specific viruses, so the third statement is True.
4. There isn't a vaccine for every virus due to the vast number and complexity of viruses, so the fourth statement is False.
5. You don't have to get some vaccines every year. For example, many childhood vaccines provide long - term immunity, so the fifth statement is False.
6. Viruses can take over host - cell DNA or RNA, but they are not the only entities that can do so. Some plasmids and transposons can also interact with host - cell genetic material, so the sixth statement is True.
7. Viruses can "hijack" a cell's metabolism by using the cell's resources for replication, so the seventh statement is True.
8. Viruses use host - cell enzymes to take over a cell's machinery for replication, so the eighth statement is True.

Answer:

1. True
2. True
3. True
4. False
5. False
6. True
7. True
8. True
