Two zebra fish "pink" mutants, pink-s and pink-w, lack the dark pigment stripes, are recessive and each displays an f2 3: 1 segregation pattern in crosses to the wild type. crosses between the pink-s and pink-w yield a pink f1. does this cross indicate that pink-s and pink-t are complimentary? how many genes are involved? the f1 resulting from hybridizing pink-s and pink-w is selfed. what do you expect the following f2 ratio of wildtype: pink to be?

a small object of mass 3.66 g and charge -17.6 µc is suspended motionless above the ground when immersed in a uniform electric field perpendicular to the ground. what are the magnitude and direction of the electric field?

it may be wrong but i think its a

the total distance that martina travels that day is

(distance from home to mom's office) plus (distance from mom's office to school)

plus (distance from school to library) plus (distance from library to friend's house)

plus (distance from friend's house to martina's house).

(we don't know what any of these distance actually is.)
