if there are at least 4 risers (steps) in the stairway, standard railings or handrails depending on the width and type of stairway. If the stairway is less than 44 inches wide and is enclosed on both sides, only one handrail is required, and if one side is open, only a railing on the open side is required. If both sides are open, standard railings are required on both sides. A standard railing for stairways would be between 30 and 34 inches above the forward edge of each riser.
If the stairway is between 44 and 88 inches in width, a handrail is required on each enclosed side and a standard railing is required on each open side. Any stairway over 88 inches wide must also have an intermediate railing halfway across its width. A winding stairway must also have a handrail offset for any portion of the risers with less than 6 inches depth.
Answer:
The electrical and diffusion potentials for K+ will be equal in magnitude and opposite in direction.
Explanation:
The cell potential may be defined as the potential difference between the inside of the cell and outside the cell. This difference is important for the transmission of nerve impulse.
The equilibrium condition may be defined as the condition at which the exit and the entrance of the ions will be equal. As the information in the question, Only potassium ions will move inward and outward of the cell. The potassium ions will move in opposite direction since the equilibrium has been reached.
Thus, the correct answer is option (D).
The deoxygenated blood leave the right ventricle via pulmonary artery to the and is taken to the both right and left lung. That is the deoxygenated blood is taken to alveolar capillaries of the lung . As blood flows through the alveolar capillaries it is oxygenated as carbon dioxide leaves.
