Nitrogenous bases %
human: g-19.9%, t-29.4%,
chicken: a-28.8%, %, %, c-21.5%
bacterium: a-13.4%, %, %, %

the table in figure 12–3 shows the results of measuring the
percentages of the four bases in the dna of several different
organisms. some of the values are missing from the table. based on
chargaff’s rule, the percentages of thymine bases in chicken dna
should be around
a. 28.8%
b. 19.9%.
c. 21.5%.
d. 13.4%.

cuz he is really really short, assuming an unorthodox and inherently unlucky configuration of elevator buttons…

explanation:

1. is geographic distribution

2 is increasing complexity

3 is transitional forms

igneous rocks are formed by solidification of cooled magma (molten rock), with or without crystallization, either below the surface as intrusive (plutonic) rocks or on the surface as extrusive (volcanic) rocks.  

the composition depends on the source magma. there are almost a thousand types of composition found till now.
