A genetic mutation, defined as being a change in the DNA base sequence would lead to a change in the primary structure of a protein (a change in the amino acid sequence). This would lead to a change in the s...

High Hydrostatic Pressure at the Arteriole end of the capillary. This pushes water and other small molecules out of the capillary into the extra cellular space, whilst proteins stay in the capillary because ...

The action potential has been propagated along the axon of the neuron causing the depolarisation of the membrane. When this action potential reaches the end of the neuron, or the synapse, it also depolarises...

At the arterial end of a capillary the blood is under a fairly high pressure. This hydrostatic pressure 'squeezes' a fluid called tissue fluid out of the pores in the walls of the capillary (fenestrations). ...

Increase temperature means molecules have increased kinetic energy and so move around more . Increasing the frequency and power of collisions leading to more enzyme substrate complexes forming and increasing...
