Re: BMR of Rat is higher than an an Elephant

... and geometry. lets say that the rat is represented by a 3d shape like a cube, 0.1 m each side. SA of a cube = 6 x L x W = 6 x 0.1 x 0.1 = 0.06 m squared V of a cube = L x W X H = .001 m cubed the SA:V ratio here is 0.06/0.001 = 60 lets say an elephant is also represented by a 3d shape like a ...

Re:

... = 63:1 (three loci), etc. You just pick the closest number and use chi-squared test to verify… In this case 19.75 is closest to 15:1 ratio and that means two loci. ...

Re: Biology Calculation-is this correct?

so I need to calculate the surface area of a sphere then, 4*pir(squared)? I have done the division at the end because they only account for 2% of the total suface area which is 68micrometers squared. The next question is to then calculate how many transferrin ...
