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.
Answer:
b. become part of the body's structural systems.
Explanation:
- Minerals are the inorganic regulators needed for different functions inside the body.
- Minerals donot provide energy but involved in generation of energ through their metabolic function. (Hence option A is excluded)
- They provide a good medium for the protoplasmic activities (permeability of cell membrane and normal functioning of cell)
- Maintaining bod fluid balance.
- For structural units.
- Cannot be degraded in the body neither can be destroyed while cooking ( Hence option c and d are excluded)
- They become the part of the body's strctral systems (Hence option B is the right answer)
Lightweight beaks, heavy teeth, stability in flight
Answer:
The correct answer is - a. If these two mite chromosomes have different genes at different loci.
Explanation:
If it is 2n= 2, it means that it is diploid and has two sets of chromosomes in which one set comes from mother and the other from father which means parent's genes contribute to diploid equally. Both sets of chromosomes form homologous chromosome pair. Each homolog of the pair has the same gene at the same loci in diploid and if it has not the same homologous gene at the same loci these are haploid.
