In prophase I of meiosis, homologous, non-sister chromatids form connections called chiasmata at matching loci. The complex then splits to give chromatids with different combinations of genes than were pr...

(i) To find the gradient of a straight light, we take any two (different) points on the straight line and compute the change in Y divided by the change in X. So here this is; (21-3)/(9-0) = 18/9 = 2. So t...

= x(1-4x^2)From difference of two squares method,= x(1-2x)(1+2x)

The magnitude of the force is given by F = BILsin(θ) . I is the current flowing through the wire, L is the length of the wire in the magnetic field and B is the magnetic field strength. The angle θ, is th...
