Answer:

2,1,3,4

Explanation:

HIV is the acronym for the human immunodeficiency virus. Aids-causing disease that attacks the immune system which is the system responsible for defending the body from disease. Infection of this virus at the cellular level occurs when it attacks the TCD4 + cell lymphocytes, after this attack the virus binds to the receptors of this cell, although not yet coded. With the binding of the virus in the cell, the virus envelope opens and releases the viral content within the host cell, after which viral RNA uses the reverse transcriptase enzyme to transcribe its DNA that migrates to the host cell nucleus with the entry. The viral DNA in the nucleus is linked to the cell DNA, reaching the pro-virus form of HIV. Now able to replicate itself, the virus begins transcribing its RNA and can reach 100 billion copies a day in an untreated individual. At this point, the virus uses the cellular apparatus to create the other structures necessary for the release of the virus into the extracellular medium.  After this, the viral RNA created is assembled in its envelope and springs from the host cell, which may cause it to rupture.

With this, we can conclude that the correct sequence of the information exposed in the question are:  2,1,3,4.

When the skin is exposed to ______, the skin produces a molecule that is turned into vitamin d.
Aleks04 [339]

When the skin is exposed to ultraviolet rays, the skin produces a molecule that is turned into Vitamin D.

Sun is the source of ultraviolet rays important for Vitamin D production. Due to this reason, in the case of Vitamin D deficiency, it is recommended by doctor's to absorb sunlight by skin. The Vitamin D production occurs specifically by UV B rays rays which lie in the range of 290-315 nanometer.

The chemical 7-dehydrocholesterol absorbs these rays and convert to previtamin D3. Further, previtamin D3 isomerizes to Vitamin D. Other than sunlight, Vitamin D can be taken through diet. The sources include seafood like fish, fish oil, dairy products, beef liver etc. Vitamin D is required for bone and teeth formation, muscle contraction, immune system etc.
