Why most antigens result in polyclonal or heterogeneous sera?

Do cells have a way to prevent or remove viral injections of viral dna, to reduce the effect of the virus and repair broken proteins? And do cells duplicate a particular gene or genes contributing to a phenotype to reduce the impact of that and DNA not being repaired properly?

Or do they just go "whelp I'm dead 😵" and let natural selection wipe out the problem?

How much alcohol gets burned during those special cocktail mixing events where a cocktail burns?

Posted: 21 May 2021 01:56 PM PDT

Would a cocktail that burns stop burning when the alcohol got used up? So just measuring the time until the flame stops, shows the amount of burned alcohol per second in percent for example?

What methods exist to target the synthesis of Copernicium in the theorized Island of Stability?

Posted: 21 May 2021 12:30 PM PDT

Copernicium seems to have two isotopes in a theorized Island of Stability (https://en.wikipedia.org/wiki/Island_of_stability#/media/File:Island_of_Stability_derived_from_Zagrebaev.svg) with predicted half lives beyond a year. We've synthesized Copernicium already; how do we go about targeting the synthesis of specific isotopes?

Do we know how accurate the COVID antibody tests are?

Posted: 21 May 2021 10:45 AM PDT

Just wondering what the likelihood is that someone could have had COVID but not have it show on antibody tests? Would having an asymptomatic case matter?

What causes Van Karman Vortexes?

Posted: 21 May 2021 07:31 AM PDT

I always see van karman vortexes form in creeks and heard they also cause howling of wind, but I have looked everywhere and found no explaination on what actually causes them can somebody help me out?

Why does the cell membrane stay a membrane? Why don't the lipid molecules just start forming little droplets?

Posted: 21 May 2021 01:12 AM PDT

I realized I don't know that much about the dynamics of these lipids. There's a cytoskeleton around it and stuff, but still, wouldn't it be a more favorable for the molecules to form little spheres to minimize surface area with the surrounding water? What keeps them stable in this sheet structure?

Can boiling occur at a random point in a volume of fluid, or do the vapor bubbles require a surface to form on?

Posted: 21 May 2021 08:02 AM PDT

I was conducting a bit of a thought experiment where you would take a very tall column of water and put it in an environment where it should boil, like <100C at sea level. The water at the bottom of the column is under more pressure than the water in the middle, which is under more pressure than the water at the top. It may help if we assume the water in the column is at a uniform temperature, the same as the environment.

Say that in this environment, the water at the top and middle has a vapor pressure greater or equal to the pressure over the water at that point, so that bubbles of vapor can form. If the water in the bottom of the column was at such a high pressure that the vapor pressure of the bubble would not be enough to support the bubble over the pressure of the water, would the boiling appear on a boundary in the middle of the column, or off the side walls, and suddenly stop boiling when the water reaches a certain depth where the water pressure is too high?

Will phosgene gas be made if carbon monoxide is bubbled into sulfur dichloride?

Posted: 20 May 2021 10:48 PM PDT

On a similar note would hydrogen gas react directly with a chlorinating agent such as a sulfur chloride?
