Myelination allows saltatory conduction to occur, which is when the impulse 'jumps' along the axon using the nodes of Ranvier. The myelin also acts as an electrical insulator.

method: complete the squares for (x^2 - 2x ) and ( y^2 + 14y ) using the formula (b/2)^2 (where the general equation is ax^2 + bx) so that the equation becomes ax^2 + bx ...

Note: sqrt means square root, and * means multiply method (overall aim is to make x the subject): multiply both sides by sqrt(5) to get: 15 * sqrt(x) = 6 * 5further expand the right hand sid...

Ligands causes d orbitals to split. Electrons get excited to higher energy levels from ground state. Visible light is absorbed to promote electron to a higher energy leve...

First let’s break this statement down. At the core of this sentence are two consecutive multiples of 5. How can we represent these using algebra? Let’s use 5a where “a” is an integer. A consecutive multip...
