1. Drought period - in time periods where there is more precipitation there is more water availability, and when there's not there isn't.
Floods - when there are floods there is much more water available.
Population density - in places with more population there is a greater need for water supply, while in places where there is lesser people, the water supply can be smaller.
2. The land, air, and water are heated each day by the sunlight. The heat produced by the sun that hits the earth as the earth rotates is then part kept by the atmosphere that doesn't permeate all of that heating energy.
3. By evaporation. As the sun heats the ocean, there is evaporation. As the ocean moves around with its tides there is also loss of water to the air. Also by the waves and winds there is water that's lost to the air.
4. Part of that vapour will be reabsorbed by the ocean because it cools and precipitates into the ocean. Other part of it is taken with the wind to land or to upper spheres of the atmosphere.
5. Part is reabsorbed but other part isn't. The other part is taken by the wind. As a gradient, there is less water in the air then in the ocean, keeping it above the ocean.
6. There is more water in the oceans then on the land. Water remains in the air on average about 9-10 days.
7. --------
8. An average American family uses about 300 gallons of water.
9. About 22%.
10. About 27%.
then it means that they have a survival trait or otherwise known as an inherited trait for survival .. since animals do not have warm houses like us they need to develop fur or something else which means that the skill that is favorable to the environment is an inherited trait

First, convert pounds to kg,
<span> 220 lb : X = 2.2 lb : 1 kg = 100 kg.</span>
<span> Next, calculate the dosage per minute, </span>
3 mcg/kg/min x 100 kg = 300 mcg/min.
Now, Convert mcg/min to mcg/hour,
<span> 300 mcg/min x 60 min = 18,000 mcg/hour.</span>
Convert mcg/hr to mg/hour, 18,000
mcg/hr = 18.0 mg/hour.
Calculate the rate,
400 mg : 250 ml = 18 mg : X ml 400X
= 4500 X = 11.25 = 11.3 ml.
<span>So, 18 mg/11.3 ml should be infused
at <span>11.3 ml/hour</span></span>
Bacteria
Explanation:
Nitrification fixation takes place by nitrogen-fixing bacteria like Azotobacter, Klebsiella, Bacillus etc which convert atmospheric nitrogen gas into fixed-nitrogen compounds like nitrates or ammonium ions for the plants to readily absorb.
The nitrogen fixing bacteria can be free-living like cyanobacteria or live with symbiotic relationship with plants and fungi.
The chemical conversion of di-nitrogen to ammonia takes place with the help of enzymes like nitrogenase in combination with leghahemoglobin, a protein through a reduction reaction.
