Hi all, I was hoping you could help me solve this question. I’m 19 years old and recently had another growth spurt 8 months ago in my knees where I grew an inch in a week and have grown 3 more inches since, but during it I was eating a lot of soy bread, and I was wondering if the phytoestrogens in the soy bread might have caused the growth spurt leading to a premature closure of the growth plates in my knees and thus stunting my growth, or if I was just genetically programmed to have a late growth spurt at this age?
I ask this because I read up that estrogen and testosterone convert to estradiol, which is the hormone responsible for the growth plates in our bones closing and I was unsure if the phytoestrogens in the soy bread I was eating could do the same thing which might explain my sudden growth spurt, much in the same way that taking steroids can produce a sudden growth spurt but lead to premature closure of the growth plates due to rapid conversion of testosterone into estradiol

This is a real-world problem and not somebody's homework or some stumper of a trick question. I know it's not hard but I can't quite remember how to do it. We have a combination lock at work. I do not know how old it is, but nobody knows the combination. It has 5 buttons, 1 through 5, and the combination is a 4-digit one with repetition allowed.

So how many possible combinations are there? If there's not too many I'll just try 'em all. Not much to do there sometimes.

All we see are lights, shiny objects, etc., etc. They must be using some sort of cloaking device to hide themselves fromn our view of their ships. If they are already here on earth, they could be using a hand-held cloaking device to cloak themselves also. What do you think?

Little has been known whether the contents of the inside of the earth can be exposed by man.

Digging into the earth is a very hard and imposible job so one can dig as deep as possible and then blast the remainder by nuclear. green land is most favored to conduct such experiments as there are no inhabitants.
Has there such event ocurred and if not where on Earth has man been able to dig into the Earth reaching close to the intrior of the Earth?
