the genome led to some giraffes inheriting the trait for long necks. over time, there were more giraffes with long necks in the region. what are
the two reasons for the change in the population of giraffes?
adaptation
o
artificial selection
natural selection
analogous structures

Carbon is allowed to diffuse through a steel plate 15 mm thick. the concentrations of carbon at the two faces are 0.65 and 0.30 kg c/m^3 fe, which are maintained constant. if the preexponential and activation energy are 6.2 x 10-7 m2 /s and 80,000 j/mol, respectively, compute the temperature at which the diffusion flux is 1.43 x 10^-9 kg/m^2 -s.
