Some plants grow in soils as high as 20% iron. If the iron is present in the form of Fe(OH)3, the plants can still be iron deficient. Explain how this can be true.

Explanation:

It is known that is insoluble in water. As a result, plants are not able to absorb readily through osmosis.

Therefore, the in would be released in acidic environments, using neutralization, Iron(III) ions can be released.

Hence, the easiest way is to add low concentrations of to the soil is as follows.

Thus, we can conclude that is soluble and is good for plants too.

why is arctic sea ice important? arctic sea ice keeps the polar regions cool and moderate global climate. sea ice has a bright surface; 80 percent of the sunlight that strikes it is reflected back into space. as sea ice melts in the summer, it exposes the dark ocean surface.

warm front forms when a moist, warm air mass slides up and over a cold air mass. as the warm air mass rises, it condenses into a broad area of clouds. a warm front brings gentle rain or light snow, followed by warmer, milder weather.
