Explain how applying increasing pressure to a Pacinian corpuscle produces a larger change in membrane potential.

When pressure is applied to a Pacinian corpuscle the membrane is distorted, opening the stretch-mediated Na+ channels. This then allows Na+ ions to move in down their concentration gradient which increases t...

Integrate 2x^4 - 4/sqrt(x) + 3 dx

First we will simplify 4/sqrt(x) so it is easier to integrate.sqrt(x) is equal to x 1/2 , therefore 4/sqrt(x) = 4/x 1/2 .We bring up x 1/2 so 4/x 1/2 becomes 4x -1/2 .So now we will integrate the simplified ...

There are green and red counters in a bag. There are 30 counters in total. The ratio of red to green counters is 1 : 5. There are 5 red counters in the bag. How many green counters are in the bag?

There are 30 counters in total in the bag. If we visualise the ratio as there being x red counters and 5x green counters, we find that there are 6x counters in total in the bag, and thus we can conclude that...
