1 Coelomate animals or Coelomata (also known as eucoelomates â true coelom) have a fluid filled body cavity called a coelom /ËsiËlÉm/ with a complete lining called peritoneum derived from mesoderm (one of the three primary tissue layers).he coelom allows muscles to grow independently of the body wall â this feature can be seen in the digestive tract of tardigrades (also known as water bears) which is suspended within the body in the mesentery derived from a mesoderm-lined coelom.
At a 3 percent growth rate, its doubling time â or the number of years to double in size â is 23 years. (The doubling time for a population can be roughly determined by dividing the current growth rate into the number 69. Therefore, 69/3=23 years. Of course, if a population's growth rate does not remain at this rate, the projected doubling time would need to be recalculated.)
Of course the rate of growth has varied as time goes on, but if 8 years to double is an average, that's 8/ln(2) = 11.5 years as a characteristic time. That's around 150 months, giving a grand total of 4 trillion french fries.gain with a 12 year time constant that gives us 4 trillion fries. Another answer site also cites a trillion as an order of magnitude, but they used the word um in their answer so I don't trust them very much.[7]. [1] http://en.wikipedia.org/w iki/McD...
