Klio2033 [76]

Answer:

Concentration gradient

Explanation:

When the concentration of molecules and ions is compared to the concentration of ions and molecules in another area, the difference in the concentration will be called the concentration gradient.

The concentration gradient is the factor which determines the rate and direction of the molecules and ions in the environment which could be physical or biological.

Why can't we see chloroplasts in onion cells even though they have them?
sergejj [24]
 <span>Because the chloroplasts that actually photosynthesize are found in the tops of the onions - the part that is actually above ground. There's no reason for there to be chlorophyll in the onion skin itself because these grow underground :)</span>

At different places one earth, depending on elevation, air pressure varies. What causes air pressure?
sleet_krkn [62]
Weight of air

Depending on elevation, the air pressure varies. This is because of the weight of the air that is exerting pressure on earth. At higher elevation, there is less layer of air that is exerting pressure so the atmospheric pressure is also less. At lower altitudes or at sea level, more layer of air is exerting pressure so the atmospheric pressure is also more. The sun’s energy has nothing to do with air pressure. The energy that the Earth gets from the sun is more or less constant. The same with density of nitrogen, and the earth’s magnetic field, they have nothing to do with air pressure.
