........... the membrane potential will become more POSITIVE.
A membrane become depolarize when sodium enters the neuron via chemically gated sodium channels, this means that, the membrane become more positive when sodium ions diffuse into the cells.<span />
Limestone.
It is a sedimentary rock composed of calcite and aragonite. It is used as a building material mainly because it is easily available and easy to work with.
Limestone is used in the manufacture of steel as it is the primary raw material that helps to remove impurities from the iron ore and produces waste matter that has low melting point and viscosity
Each cell is alive even if it is part of a multi celled body, and all living organisms consist of one or more cells. Also, cells reproduce by dividing so it follows that all existing cells must have arisen by division of other cells. As a cell divides it passes it hereditary material- its DNA- to offspring.
A. If the optimum temperature for a cell's functions is exceeded, chemical reactions slow down as enzymes and other proteins begin to denature (change shape due to increased vibration of the atoms in the molecules that make up the proteins).
