Would a diet of chocolate soy milk (pic related) and water be sufficient enough if i take multi vitamins with it?

Long story short im allergic to something in regular food so until i get it tested i have to live off a "food" that doesnt cause a reaction so picked chocolate soy milk.

I can drink around 4 litres of it per day.
I seems to have enough calories, a decent amount of fat and protein. Not that much carbs but people go on a low carb diet all the time.

Can someone more knowledgeable give me some advice?

What's stopping some disgruntled lab technicians from sneaking home one dangerous bacteria or another, growing cultures of it periodically exposing it to every antibiotic they can get then releasing it in a airport or something?
It just seems strange that with so many people in the position to do this there hasn't been any domestic bio-terrorism.

For most terrorists, the costs of escalation to biological weapons would seem to outweigh the benefits. Most modern terrorists have had substantively rational goals, such as attaining national autonomy or establishing a government purportedly more representative of the people's will. Escalating to such frightening weapons would result in a massive government crackdown and could alienate the group's supporters. Biological weapons are also dangerous to produce. A number of Aum Shinrikyo members reportedly damaged their own health while working on biological agents. Additionally, some terrorists may perceive moral constraints

If it's log base 10 then you set both sides as the exponent of 10.

log(10^x) = x = 10^log(x)

However I've see log used as notation for base e, in place of ln(). So just be sure you're dealing with log base 10. If it is e then you just set both sides of the equation as the exponent for e

I don't know about the rest of what you're claiming, but dwarfism is usually comorbid with a bunch of other problems that can lower life expectancy. It isn't the dwarfism itself.
>>
>>9149986
Dwarfism != Being naturally short
Dwarfism is a disease. One of its symptoms is shortness. It is not shortness in and of itself.

>>9149986
In general (read: across mammals) the smaller an organism the higher its heart rate and metabolic rate so the shorter it lives. As a guess I would assume that's due to needed to maintain a body temp with a larger surface area to vol ratio

Explain to me how things with 2 heads work

>If 1 swallows something, does the other feel full?
>If one limp gets touched, which head feels it?
more facts please

it is just 2 bodies stuck together, the only thing they share is blood
>>
>>9149828
>If 1 swallows something, does the other feel full?
Depends if they share a stomach or not. Sometimes they do, sometimes they don't.

>If one limp gets touched, which head feels it?
Each head feels (and controls) its side of the body.

Conjoined twins can differ in how far they're conjoined. Sometimes they share organs, sometimes they have their own sets of organs, there's a lot of variety.

I think he said it will happen in December. Could be wrong tho.

Probably the most retarded question asked on here in a while, but how does chemistry actually work? I understand that molecules exchange electrons, but I don't quite understand how you can say that CH4(g) + 2O2(g) --> CO2(g) + 2H20(g) without literally doing it in a lab first. Is there a chemistry book that explains shit properly?

Let's do something legit now.

Show that over any local Artinian ring, any free submodule of a free module is a summand. Deduce that the only modules of finite projective dimension are the free modules. Over the exterior algebra, show that any free submodule of any module is a summand.

If you had a collection of users and the messages they've sent to each other over an arbitrary amount of time, how would you go about deriving the similarity of one user to another? I was thinking of checking word use and length, message length, etc, but I'm not sure if I'd get a useful spread that way.

you get there most frequently used words and classify it by music, science, tech, video games, movies, etc. this will describe a person's interests and compare it with others

The problem with that is now you have to get into the business of deciding what goes in which category.

we cant seriously believe in the multiverse theory can we?
it is maybe the only way to explain the infinities in the zero point energy, but i dont even think it fits with that.

this and the big bang theory:
we must be in a part of the universe which is detatched from the light cone of the centre of the universe. we can not see the universal black hole which must have emerged from a pointlike source inflationary universe. if not where is it? why no supermegamassive blackhole in the middle of the universe?
