Answer:
Watershed: A drainage basin
Divide
: A high land area that separates one watershed from another
The _____ passively diffuses oxygen and carbon dioxide in and out of the cell.Through the plasma membrane, oxygen and carbon dioxide diffuses passively.
However, it is thru a transport that they in act to diffuse, -concentration gradient.
I would <em>PROBABLY</em> say C; Method A is radiation and Method B is conduction. My reason for that is because Method B sounds a lot like conduction to me and Method A sounds like it COULD be radiation? I'm sorry if this is wrong, it just seems like the best choice in my opinion!
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.
