Explain how rate of diffusion principle is used while filling air in the rubber tubes to increase the speed of the vehicles.
No, filling a balloon with a helium pump is not an example of diffusion. Instead, it involves the active transfer of helium gas into the balloon under pressure. Diffusion, on the other hand, refers to the natural movement of molecules from an area of higher concentration to an area of lower concentration, which occurs passively without external force.
Well i think it is not🤬🤬🤬🤬🤬💋💋👙👙👗👗👗🩲🩲👛👛💍💍
When sugar is dissolved in water, the volume increases slightly due to the spaces between water molecules filling with sugar molecules. However, this increase is typically negligible for practical purposes since sugar dissolves readily in water.
Increasing venous return would increase end-diastolic volume (EDV) by filling the ventricles with more blood before contraction. This increased preload would stretch the myocardium further, leading to a more forceful contraction and increasing stroke volume.
Increasing end-diastolic volume (EDV) enhances stroke volume due to the Frank-Starling mechanism, where greater ventricular filling leads to stronger contractions. Higher end-systolic volume (ESV) can also increase stroke volume when it results from reduced afterload or increased contractility, allowing the heart to eject more blood with each beat. Thus, both EDV and ESV can influence stroke volume, primarily through changes in the heart's filling and pumping efficiency.
Yes, it is.
yes because once you smoke the cigaret spreads
Only in fleet vehicles doing local duty. CNG filling stations are not plentiful.

Smoke filling up a room is an example of diffusion because the smoke particles move from an area of high concentration (where the smoke is generated) to an area of low concentration (the rest of the room) in order to reach equilibrium. This is due to the random motion of the smoke particles.
yes
Na, as it's in group 1.
alveoli are arranged in grape like groups to increase surface area in which gas exchange takes place, the walls are very thin just big enough for on cell to pass so that there is an increase in rate of diffusion, walls of alveoli are moist so it also increases the rate of diffusion and the alveoli can stretch so that it prevents the alveoli form over filling with air and damaging the thin walls
Gas has no fixed volume or shape, therefore using diffusion to fill the empty spaces and filling the container.
It doesn't - "contractility" refers to the force generated at any given length of muscle. Therefore although the force of contraction does increase with filling, the contractility does not.The reason the force of contraction increases with filling is because filling stretches the heart muscles. Increased stretch causes an increase in force of contraction.Contractility changes because of changes in the level of intracellular calcium. This can be changed by things such as adrenalin (epinephrine), which increases contractility and β blockers, which decrease contractility.
