Our bodies have 3 billion genetic building blocks, or base pairs, that make us who we are. And of those 3 billion base pairs, only a tiny amount are unique to us, making us about 99.9% genetically ...
In the empirical sciences, the so-called three-sigma rule of thumb (or 3 σ rule) expresses a conventional heuristic that nearly all values are taken to lie within three standard deviations of the mean, and thus it is empirically useful to treat 99.7% probability as near certainty.
Nearly all (>99.9%) of these sites are small differences, either single nucleotide polymorphisms or brief insertions or deletions in the genetic sequence, but structural variations account for a greater number of base-pairs than the SNPs and indels.
The purity of a gas is generally expressed as a grade prefixed with the letter N (rather than postfixed), indicating the "number of nines" in the percentage or decimal fraction. For example, a N2.0 gas is 99% (two nines) pure and 1% impurities by volume; a N6.0 gas is 99.9999% (six nines) pure, with 1 part per million (1 ppm or 1 vpm, volume ...
The global literacy rate for all people aged 15 and above is 86.3%. The global literacy rate for all males is 90.0%, and the rate for all females is 82.7%. The rate varies throughout the world, with developed nations having a rate of 99.2% (2013), South and West Asia having 70.2% (2015), and sub-Saharan Africa at 64.0% (2015). [ 1 ]
Unlike the limited systems of other animals, human language is open – an infinite number of meanings can be produced by combining a limited number of symbols. [ 356 ] [ 357 ] Human language also has the capacity of displacement , using words to represent things and happenings that are not presently or locally occurring but reside in the ...
Africa's population is the youngest among all the continents; [10] [11] the median age in 2012 was 19.7, when the worldwide median age was 30.4. [12] Based on 2024 projections, Africa's population will reach 3.8 billion people by 2099. [13] Africa is the least wealthy inhabited continent per capita and second-least wealthy by total wealth ...
[52] [54] However, the 1931 British census showed only 3,524 Armenians in all of Palestine. [52] A large number of Armenian monks are recorded to have settled in Jerusalem as early as the 4th century, [55] [56] after the uncovering of Christian holy places in the city. [52] However, the first written records are from the 5th century. [57]
