How does the increase of resistance to antiviral drugs in HIV relate to the theory of evolution by natural selection?
The ones with worse resistance are less suited to suvival, and hence are selected against by being destroyed by antivirals more often. When repeated, this means successively more and more of each generation is highly resistant, or that the reistsance is higher in each one. This is almost exactly the definition of natural selection, replacing the general trait with the specific resistance to antivirals.
How will the speed of sound through a gas increase?

Does a catalyst always increase the rate of reaction or it may decrease it also?
A catalyst typically increases the rate of a reaction by providing an alternative pathway with lower activation energy. However, in some cases, a catalyst may decrease the rate of a reaction if it facilitates a different reaction pathway that results in the formation of different products.

What makes prescription drugs so addictive?
The drugs themselves are the chemicals/molecules. There is nothing that can be removed or changed to make them non-addicting. The nerve cells in the brain have receptor sites that accept only certain kinds of molecules that are produced by the brain -- one kind for each kind of receptor. Some of those molecules trigger feelings of pleasure. The drugs mimic those molecules and attach to the receptor sites, or they stimulate production of the feel-good drugs. Either way, when the supply increases the brain responds by building more receptor sites for that particular molecule to handle the increased supply. Eventually that means that we have to take more of the drug to get the same effect. That is called "tolerance," and it is usually the first sign of addiction. As we take more and more of the drug, it replaces the normal chemicals in our brain and our body perceives that we don't need them any more. So it shuts down production. Then, when we stop taking the drug, all those extra receptors are left empty and our brain tells us we really, really need more drugs. If we don't get them, we go into withdrawal.
Drugs increase therapeutic response of otc drugs?

In general parasympathetic activation will produce effects that are to those produced by activation of sympathetic neurons?
Parasympathetic activation tends to have opposite effects to sympathetic activation. This means that parasympathetic activation typically promotes "rest and digest" functions such as slowing heart rate, promoting digestion, and relaxing muscles, while sympathetic activation triggers the "fight or flight" response, increasing heart rate, dilating airways, and redirecting blood flow to muscles.
