1. A closed manometer is filled with mercury and connected to a container of nitrogen gas. The level of the mercury is 821 mm higher
than the arm connected to the container of nitrogen. What is the
pressure of the nitrogen in kPa?

Jenny wants to test the electrical conductivity of two substances dissolved in water. she is preparing the containers for the experiment. which factor is most important for her to control?

In most resting cells, the concentration of sodium ions is higher outside of cells compared with the intracellular fluid. when cells are stimulated, sodium ion channels open, and sodium diffuses from the outside of the cell to the inside of the cell. sodium ion concentrations in a resting cell are an example of and sodium ion movement in a stimulated cell is an example of in most resting cells, the concentration of sodium ions is higher outside of cells compared with the intracellular fluid. when cells are stimulated, sodium ion channels open, and sodium diffuses from the outside of the cell to the inside of the cell. sodium ion concentrations in a resting cell are an example of and sodium ion movement in a stimulated cell is an example of potential energy; kinetic energy kinetic energy; potential energy the energy of motion; stored energy chemical work; energy stored in chemical bonds
