How might mutations introduce variation into population

See explanation for example

Explanation:

Mutations are changes in DNA. They change the way a stretch of gene is produced or reacts. Therefore, if mutations occur rapidly, it could introduce variations of actually anything!

see the picture for the vector

the magnitude of the vector by pythagorean theorem

r = √( (-10)^2 + (3)^2 ) = √109

magnitude = √109 units

the direction angle between vector and x-axis is

tan^(-1)(3/10) = 16.699

so the direction is approximately 16.7 degrees north of west
