How does natural selection change the frequency of genes or traits over many generations? biology students conducted an experiment mimicking genertic variation and coloration students used different colored beans to represent animals that might be prey: mice for example. A student in each group was the predator: a hawk. beans.(mice) were randomly scattered on multicolored floor tiles, each color within four tiles The hawk collected mice (beans) for 10 seconds. mice not eaten reproduced. Three generations of data a shown in the table. All BUT ONE could be a reason for the color variation in the mice . that is A) meiosis

B) mutations

C) genetic variation

D) ase xual reproduction

please answer i'm on a test

Part a determine the magnitude of the x component of f using scalar notation. fx f x = nothing lb request answer part b determine the magnitude of the y component of f using scalar notation. fy f y = nothing lb request answer part c determine the magnitude of the z component of f using scalar notation. fz f z = nothing lb request answer provide feedback figure1 of 1a force vector acting on a ring attached to the ground is shown in the xyz space together with its x, y, and z components lying on the corresponding positive axes. the ring is located at the origin. force f is located in the first octant. f makes an angle of 60 degrees with its x component and an angle of 45 degrees with its y component. a force vector acting on a ring attached to the ground is shown in the xyz space together with its x, y, and z components lying on the corresponding positive axes. the ring is located at the origin. force f is located in the first octant. f makes an angle of 60 degrees with its x component and an angle of 45 degrees with its y component.
