When neurons are not producing electrical signals we say that they are at resting phase: voltage across their membrane is called the resting membrane potential, or the resting potential.
This potential is determined by the concentration of ions (Na, K) across the membrane and by membrane permeability to each type of ion. While the ions move through channels down their gradients they lead to a separation of charge and that is what creates the resting potential.
The membrane of the neuron is much more permeable for K ions so the resting potential is close to the equilibrium potential of K+.
Explanation:
The cell must be lysed (broken open) to release the nucleus. the nucleus (if present) must also be open to release the DNA. at that point the DNA must be protected from enzymes that will degrade it, causing shearing. [[ once the DNA is released, it must then be precipitated in alcohol...]
Answer:
The visible bodies of water are referred to as surface water. The majority of fresh water is actually found underground as soil moisture and in aquifers. Groundwater can feed the streams, which is why a river can keep flowing even when there has been no precipitation.
Explanation:
The measurements taken by Jay are least likely to contain random errors.
When you increase the number of measurements, the random errors tend to minimize, because errors in one direction cancel with errors in the opposed direction.
