[quote="rookie1ja"]Biology - Back to the Logic Puzzles
Let's say some primitive organisms divide themselves every minute in two equal parts that are the same size as the original organism, and which also divide the next minute and so on [wording amended]. The saucer in which we started observing this process was full at 12.00.
When was it half full?[quote]

I'd like to know what time this division started. I don't see it mentioned. Maybe it doesn't matter and I'm missing the point. That would be just great.

It does not matter what time the division started

Clearly, this isn't about Biology... It's about Science Fiction

If the cells would divide themselves in two, the two parts would each have half the mass of the original. If they grew to the size of their parent in only one minute, their would need to be plenty of food for them in the bowl, cup or whatever-it-was. This means, that the bowl must have been completely full all the time, from the start of the experiment right until the end! This wood make the whole riddle irrelevant or, if the bowl was NOT full, SciFi

For some, maybe. For others, a LOGIC puzzle is all about scientific thinking. You wouldn't read fairy tales to help you on your discrete math test, would you

it's been many years since my last math test ... I like finding solutions and making things as easy as possible ... I thought that this was a puzzle for 10-year-old kids

sooooo, no flame here (I will delete all such posts)

I must apologize. My remark, which obviously started this, was just intended to be humorous, not the start of a flame war. Maybe I could've been more clear about that.
Sorry.

The question simply states that the organism/s displaced x amount of volume at 12.00, previously stating that it doubles every minute. I conclude that at 11.00 the organism/s displaced HALF of what was is displaced at 12.00.

It was half at 11.00

I don't see why people are decrying logic on this puzzle and no others. I didn't see anybody complaining about other peoples' answers to the ball throwing riddle (ex. Throw the ball around the entire planet, lol).

I would say in this one instance the nay-sayers are RIGHT. This puzzle is ridiculously illogical. My first question when I read it was "what is the size of each organism?" Then I thought; "nevermind that, there's no indication of growth to time ratio."

How is it fair to have a size/biology riddle where the answer never takes into account size or biology? It simply never acknowledges that it takes time for an organism to grow. Because it was written wrong from the get-go on the logic flaw that an object divided would ever get Bigger. I say this one time, it is wrong. The only logical answer is "It is never half full".

Or more simply, if the 2 divided organisms are the same size as the original, when? When are they the same size? Instantly? Then the organism didn't divide, it doubled and split! If they continue this process then the two new organisms will double and split. This isn't even a logic problem its a math problem. Math angers me. arrggh.

Actually, because it is an organism, it needs dead or dying cells to feed itself. So, it had to eat half of the cells and then replenish them several times.
