DNA helicase is the enzyme that unwinds the DNA double helix by breaking the hydrogen bonds down the center of the strand. It begins at a site called the origin of replication, and it creates a replication fork by separating the two sides of the parental DNA.

Answer:
D. The virus uses the host cell to make new viral parts.
Explanation:
The virus is an organism that is incapable of replicating on its own without a living host cell. It needs to infect a living cell in order to reproduce. The infection cycle of a virus is the replication cycle. Viruses employ two major infection cycles: LYTIC or LYSOGENIC cycles.
In the lytic cycle, the virus initially attaches to specific receptor sites on the host cell membrane. It then penetrates the host cell and incorporate its genetic material into the host cell's genome. It employs the host's ability to express its genes and replicate to express its genes and make new proteins. At the end of the LYTIC cycle, new viral particles (virions) are produced and released by lysis of the host cell.
<h2>Answer:</h2>
<u>Energy flows from the producer level to the consumer level.</u>
<h2>Explanation:</h2>
In any ecosystem, Producers are those species which make their own food. The best example is any kind of green plant. Green plants make their food by taking sunlight and using the energy to make sugar. On the other hand The organisms that obtain their energy from other organisms are called consumers. All animals are consumers, and they eat other organisms. So we can see that energy always flows from producers to consumers.
Analogous, because, they are similar in some respects. Hence the definition of analogous
