AI Thread Summary
HIV can remain asymptomatic for a long period because it primarily weakens the immune system without immediately causing symptoms. The deterioration of T helper cells must reach a critical threshold before the body becomes susceptible to opportunistic infections. Individuals with a strong immune response can fend off other diseases despite being HIV positive, which explains the absence of symptoms. The progression to AIDS occurs not from HIV itself, but from secondary infections that exploit the weakened immune system. Therefore, a person can be infected with HIV and remain symptom-free if their immune system remains robust.

Thanks

The number of T helper cells needs to go below a certain critical value before cell-mediated immunity is lost and the body is more susceptible to infections.
 
that's true, but why is it that they may not exhibit any symptoms?
 
Because it's not HIV that kills you, it's the other diseases that gain an easier access into your body that kills you. If your body is strong enough to fight off the other diseases while being infected with HIV, then why would you show symptoms?
 
ahh ok thank you!
 

Thread 'Prove that evolution is constant (Provide at least two arguments to support your position)'

I don't get how to argue it. i can prove: evolution is the ability to adapt, whether it's progression or regression from some point of view, so if evolution is not constant then animal generations couldn`t stay alive for a big amount of time because when climate is changing this generations die. but they dont. so evolution is constant. but its not an argument, right? how to fing arguments when i only prove it.. analytically, i guess it called that (this is indirectly related to biology, im...
