How long does it take for a photon to travel through the convection zone

Biology
1 answer:
Bas_tet [7]2 years ago
3 0

Answer:

50 million years

Explanation:

It can take a photon as long as 50 million years to travel all the way through the radiative zone. The convection zone surrounds the radiative zone. In the convection zone, hot material from near the Sun's center rises, cools at the surface, and then plunges back downward to receive more heat from the radiative zone.

jekas [21]

Answer:

c. There will be a net diffusion of oxygen from the water into the bloodstream only if the partial pressure of oxygen in the water is greater than 100 mm Hg

Explanation:

Diffusion involves the movement of molecules from the region of higher concentration to the region of lower concentration. If the molecules are gas molecules, they will diffuse from the region of higher pressure to the region of lower pressure.

Hence, for net diffusion to occur from the water to the bloodstream, the partial pressure of oxygen in water must be higher than the partial pressure of oxygen in the bloodstream.

<em>Since the partial pressure of oxygen in the bloodstream is 100 mm Hg, then the partial pressure of the gas in water must be more than 100 mm Hg in order for net diffusion to occur from water to the bloodstream.</em>
