vekshin1

Answer:

B) aorta to smaller systemic arteries to systemic capillaries to systemic veins to right atrium through the triscupid valve

Explanation:

Oxygenated blood from the right ventricle is pumped into the aorta. Aorta is the largest systemic artery that obtains oxygenated blood directly from the heart. Many systemic arteries get oxygenated blood from the aorta. Exchange of oxygen between blood and tissue cells occurs in systemic capillaries.

The deoxygenated blood from tissues is picked by systemic veins. The deoxygenated blood from systemic veins is delivered to the right atrium via vena cava. The blood is pumped from the right atrium to the right ventricle through the tricuspid valve from where it is carried to the lungs for oxygenation. The oxygenated blood from the left atrium is pumped to the left ventricle and finally into the aorta.

A potential difference of 100 mV exists between the inner and outer surfaces of a cell membrane. The inner surface is negative r
torisob [31]

Answer:

1.602 × 10⁻²⁰ J

Explanation:

Since the sodium ion Na has a positive charge, the work done in moving it from the interior of the cell to the exterior of the cell is W = qΔV where q = charge on sodium ion = +1 and ΔV = potential difference between inner surface of the cell and outer surface of the cell. Since the inner surface of the cell is negative relative to the outer surface, the sodium ion moves from a lower potential to a higher potential. So, the potential difference is ΔV = + 100 mV = 0.1 mV = 10⁻¹ V

Also, q = +1 which is one unit of charge. So, q = +e where e = electron charge = +1.602 × 10⁻¹⁹ C

So, W = qΔV (Note that the work done is positive since we have to input work into the cell to move a positive charge from lower to higher potential)

So, substituting the values of the variables into the equation, we have

W = qΔV

W =  +1.602 × 10⁻¹⁹ C × 10⁻¹ V

W =  +1.602 × 10⁻²⁰ J
