I believe the question is according to the attached image.
The order of the diagram that would show primary succession in an area that had never before been occupied by living organisms is;
C,A, B, D.Primary succession occurs in lifeless areas; these are regions in which soil is incapable of sustaining life as a result of factors such as lava flow, newly formed sand dunes, or rocks left from a retreating glacier.
The presence of sea-dwelling organism fossils indicate that, at one time, the area was under water.
Answer:
The lytic cycle.
Explanation:
<u>HIV is a retrovirus</u> that has a special enzyme called transcriptase reverse, which can synthesize DNA using RNA as a template. This replication system is particularly useful for the virus because the DNA synthesized from the RNA viral genome can be then integrated into the human chromosomes and stay inactive for years. This is called a lysogenic cycle and is characterized by a latency of the virus and an integration to the host DNA.
When there is a triggering event, <u>this latent virus can be excised from the human chromosome and start producing copies of itself using the host machinery.</u> <u>Then the virions are assembled and after that they lyse the host cell and release new infective units that can then infect neighboring cells. </u>This is called the lytic cycle of the virus and is the reproduction cycle that occurs when a person moves into the acquired immunodeficiency syndrome (AIDS) stage of HIV infection.
