A virus needs a host cell to replicate the virus's DNA in order to multiply.
In order for a virus to multiply, it needs a host cell to replicate its DNA. A virus cannot reproduce on its own as it lacks the necessary cellular machinery to do so. Instead, it injects its genetic material into a host cell, taking control of the host cell's machinery to replicate its own DNA. This allows the virus to produce multiple copies of itself, which eventually leads to the spread of the viral infection. Therefore, the correct response in this case would be "A host cell to replicate the virus's DNA."
Which statement best describes viral reproduction?(1 point) Responses Viruses may contain DNA or RNA. Viruses may contain DNA or RNA. Viral nucleic acid is inserted into a host cell where it may replicate immediately or become dormant until a later time. Viral nucleic acid is inserted into a host cell where it may replicate immediately or become dormant until a later time. The lysogenic phase of viral replication causes cell death while the lytic phase of viral replication results in prophage formation. The lysogenic phase of viral replication causes cell death while the lytic phase of viral replication results in prophage formation. Viruses reproduce independent of cell based organisms.
Viral nucleic acid is inserted into a host cell where it may replicate immediately or become dormant until a later time.
Which of the following is the equation for cellular respiration?(1 point) Responses 6 CO2 6 ADP light → 6 O2 6 H2O 6 CO 2 6 ADP light → 6 O 2 6 H 2 O 6 CO2 6 H2O → 6 O2 6 ATP 6 CO 2 6 H 2 O → 6 O 2 6 ATP 6 CO2 6 H2O light → 6 O2 6 C6H12O6 6 CO 2 6 H 2 O light → 6 O 2 6 C 6 H 12 O 6 6 C6H12O6 6 O2 → 6 H2O 6 CO2 ATP
6 CO2 + 6 H2O → 6 O2 + 6 C6H12O6 + ATP

Which of the following describes how lysogenic virsuses are different from lytic viruses.(1 point) Responses Lysogenic viruses only infect plant cells and lytic viruses only infect animal cells. Lysogenic viruses only infect plant cells and lytic viruses only infect animal cells. Lysogenic viruses are made of DNA. Lytic viruses are made of RNA. Lysogenic viruses are made of DNA. Lytic viruses are made of RNA. Lysogenic viruses are cellular and lytic viruses are not. Lysogenic viruses are cellular and lytic viruses are not. Lysogenic viruses do not cause the host cell to burst right away and lytic virsuses do immediately cause the host cell to burst.
Lysogenic viruses do not cause the host cell to burst right away, while lytic viruses do immediately cause the host cell to burst.
