Answer:
Diffraction
Explanation:
Diffraction is the key explanation why we can hear sounds around corners but not see them. As compared to light waves, sound waves have much longer wavelengths, making diffraction effects much more visible. When the size of the object that the wave is diffracting around is about the same as the wavelength of the wave, diffraction effects become very visible.
Sound has a wavelength of 1 m, while light has a wavelength of 0.1 micro m. Reflection is a secondary reason. Sound waves bounce off walls in a specular way, allowing them to bounce around corners, but light bounces off walls in a diffuse manner.
hope this helps :)
The above statement is an example of an vestigial structures form of evolutionary evidence. Vestigial is an organ that was useful once in an an organism's evolutionary past.
First we establish a table of genotypes and phenotypes:
genotype phenotype
AA type A
BB type B
AB type AB
Homozygous type A has genotype AA
Homozygous type B has genotype BB
Now we make the punnett square
A A
B AB AB
B AB AB
So we see that all (100%) of outcomes are type AB.
