thanks for replying, I there are certain distinctions made in meaning of these terms for use limited to certain articles as people define bird sounds based on complexity, Length, stimulus/inspiration[ e.g. sexual stimulus, predator etc.];.. PS: Sorry for posting it here rather than in Zoology forum,...

BIrd SOng And Bird Whistle.

Does anyone know if there is any difference between bird songs & bird whistles? Or what is the precise definition of these two words..?

Sodium ion concentration also influences the O.D. I think the factors influencing the multiplication of bacteria can effect the O.D. %viability also effects the O.D. I think these will total to too many factors influencing the O.D. , But i think many of them will produce minor variations... ain't it?

thanks for the reply, We have used E. coli, so this relation may be checked for in this case. Which factors influence the O.D. of a bacterial suspension..? I think, mass concentration [mass/vol], number concentration[number/vol], or percentage volume are related to each other and thus to O.D. also.

O.D. and cell number

What is the relation between O.D. of a bacterial culture [ in log phase atleast] and the number of cells? O.D. when plotted against time , a straight line is obtained for a log phase culture...this resembles the graph of logN [N is number of cells] Vs time. what does it indicate about mathematical r...

greater no. of chromosomes may or may not mean greater genetic variation, and the variation at a particular locus is also required in the population...And the availibility of raw material is an important point, so the rate of change of gene frequencies in the adaptive landscape also depends upon the...

par'SIMONY.

par'SIMONY! Its sometimes amaizingly intuitive to accept the less stepped process to be more likely WHEN NO BIAS IS PROVIDED LOGICALLY , n this is what we do when we accept to apply parsimony... we accept the hypothesis with minimum explanations [&/steps?] to be more likely or true! now when we ...
