Answer:
Action potential.
Explanation:
Action potential may be defined as the change of the membrane potential of the cell with response to the stimulus. The different ions enter and exit the cells.
Action potential generates in the cell when the threshold voltage - gated channel reaches and opens the voltage gate channel. The opening of voltage gated channel changes the membrane potential of the cell.
Thus, the correct answer is option (4).
Answer:
Metabolic water is a water obtained from eating other organisms.
Explanation:
Water is a by product that is gained in the process of cellular respiration. In respiration process, food molecules are broken down in the mitochondria of the cell for generating energy in the form of Adenine tri phosphate (ATP). With this ATP, water and carbondioxide is also produced. Carbondioxide is removed from the body while water is used in different processes. So desert beetle takes water from eating food substances.
