The refractory period is a period of recovery after an action potential where the ion channels will not open and the membrane can't be excited or depolar...

Area of rectangle is 20 cm². The new area of the enlarged rectangle is the original area, 20 cm², times the area scale factor. We are only given the length scale factor, therefore, w...

For this problem we want to look to split it into logical steps We first identify that it is an integration problem without limits therefore there will be a constant of integration +C present The denomina...

The order of the amino acids (primary structure) in the two proteins may be different. This can result in ionic, hydrogen and disulphide bonds to form in different locations in each protein. Such differen...

y = x^4 - 12x^2
dy/dx = 4x^3 - 24x
The turning points are where dy/dx = 0
4x^3 - 24x =0
x(4x^2 - 24) = 0 Therefore one of the turning points is at x = 0
4x^2 - 24 = 0
4x^2 =...
