..they are mostly replaced..it is a constant cycle or regenesis for most cellular components...some are retained for longer periods of time (the atoms in DNA) but mostly...you get a new body every decade or so (slowly of course and not completely.)

2) It is well documented that the first flights that juvenile bees take is an orientation flight. In this first flight the go a few feet out from the hive, fly up and down, left and right, and move a little farther away...
If a bee flys out of his hive, he knows left, right and straight, the dance tells him the relation from straight either left or right. This is always constant no matter the time of day. (IE half way between straight out and right ..would be your 45 degrees)...If the sun is used then the bees...
"Our chemistry teacher just learned about chemical kinetics"
this statement bothers me on many levels. Are they trying to teach it now? As stated above, I am not sure of your question.
I am a beekeeper and I have always felt that the dance was no as much in relation to the position of the sun, but rather the location of the hive. If it was in relation to the sun it would depend on what time of day the source was discovered and what time the dance was made. The relationship of...
Your IQ is supposed to be your intellectual age/ actual age *100 I believe. Therefore in theory it should fairly constant over a short term, but possible to change over a longer period. I don't think many people plave much value on IQ anymore due to a lot of problems with the concept of how to...
