Arbya voudrait expliquer à son frère que
la coloration prise par le toast correspond
à une transformation chimique alors que
ce n'est pas le cas du beurre qui fond.
Quel argument peut-elle donner ?​

multiple allele inheritance is traits controlled by more than 2 alleles (ex: pigeons having 3 alleles of one gene govern their feather color).

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

find the sum of the two horizontal vectors and the sum of the two vertical vectors
