Phosphorous (III) Chloride consists of one phosphorous atom covalently linked to 3 individual chlorine atoms. Phosphorous is found in group 5 of the periodic table, hence it has 5 outer shell electrons, i...

The action potential reaches the pre-synaptic knob causing depolarisation. This causes voltage-gated calcium channels in the pre-synaptic membrane to open. Calcium ions enter the pre-synaptic knob through...

If the function is even, f(x) = f(-x).cos(-x) is the same value as cos(+x) therefore the function is even. Its graphical property is that it is symmetrical about the y axis as all even functions are.

We can traditionally consider three core models which theorise how the development gap has come to exist. These are: Dependency Theory, Rostow's Modernisation Theory, and Wallerstein's World Systems Theor...
