Crime and deviance can be explained through a variety of different theoretical explanations. In order to maximise the marks you could gain if a question like this comes up, you will need to be aware of th...

The reducing ability of halide ions increases as we go down the group because the size of the ions increases down the group meaning the outer shell electron that gets lost when the ion is oxidised is furt...

In the cells lining the proximal convoluted tubule, sodium-potassium pumps present in the membrane in contact with tissue fluid pump sodium ions out of the cells. This lowers the concentration of sodium i...

By definition, diffusion is the movement of particles from a region of high concentration to a region of low concentration. It occurs in liquids and gases where particles can move freely down a concentrat...

The sodium potassium pump (sodium potassium ATPase) is an enzyme found in the membrane of all animal cells. Its job is to move NA+ out of the cell and K+ in the cell against their concentration gradient. ...
