The history of the OXO cube goes back to 1840, when it was created from an extract of beef to make meat available to those with lower incomes.It is now available in four flavors: beef, chicken, vegetable and lamb.tir the OXO cube in the water until it is dissolved. Sample the stock. If you find the taste is too strong, add more boiling water until it is to your liking. Serve the stock as a hot drink, or add vegetables, meats and other ingredients as you wish to the stock to create soup.
ION CHANNELS. Trafficking of small charged molecules (ions) thru the cell membrane of neurons determine their ability to signal and respond to each other. The electric charges of ions are in fact responsible for the membrane potential and action potential. But since the cell membrane is almost totally impermeable to ions, there is a need to use specialized cellular devices that can transport ions in and out of the cell thru the membrane. These devices are called ion channels.
Potassium ions are negative, so the inside of a cell has a slightly negative charge. Sodium ions are positive, so the area immediately outside the cell membrane is positive. There isn't a strong enough charge difference to generate electricity, though, in this resting state. When the body needs to send a message from one point to another, it opens the gate. When the membrane gate opens, sodium and potassium ions move freely into and out of the cell.
