Answer:
Ocean currents result from two processes - the action of wind on the surface of the water, and from variation in water temperature that causes movement- a process known as convection.Mantle convection is the slow creeping motion of Earth's solid silicate mantle caused by convection currents carrying heat from the interior to the planet's surface. ... This subducted material sinks through the Earth's interior.

Answer:
The rate of gaseous exchange in alveoli and blood depends on the difference in pressure of gases in both the alveoli and blood capillaries.
Explanation:
The air in alveoli has high pressure of oxygen and low pressure of carbon-dioxide.
The air in blood vessels has high pressure of carbon-dioxide and low pressure of oxygen
Due to the diffusion, the oxygen from alveoli moves towards to blood capillaries and carbon-dioxide diffuses from blood to alveoli.

<span>The presence of light and enzymes within the plant's chloroplasts act as the catalysts for the light-dependent reaction and begin the process by splitting the water molecules into electrons, protons and oxygen. Hope this answers the question. Have a nice day.</span>
