Answer:
Sample
Explanation:
Samples are used in statistical testing when population sizes are too large for the test to include all possible members or observations. A sample should represent the population as a whole and not reflect any bias toward a specific attribute.
Answer:
<em>A. a shooting star:-</em>
<em> Definitely we can't find a shooting star.</em>
<em>B. Extremely high temperatures :-</em>
<em>The troposphere is the lowest layer of Earth's atmosphere, and is also where nearly all weather conditions take place. </em>
<em>C. Clouds:-</em>
<em>As the troposphere is the lowest layer of Earth's atmosphere. Most of the mass (about 75-80%) of the atmosphere is in the troposphere. Most types of clouds are found in the troposphere, and almost all weather occurs within this layer. Air gets colder as one rises through the troposphere.Therefore the clouds are present in the troposphere.</em>
<em>D. The ionosphere:-</em>
<em>The of region ionosphere that includes the thermosphere and parts of the mesosphere and exosphere</em>
<em></em>
<em>Therefore the answer is C. Clouds</em>

Answer:
This is the best explanation for why there is such a small amount of phosphorus that moves into aquatic systems:
1. Phosphorus is highly stable in the atmosphere and remains there for long periods of time.
Explanation:
The phosphorus first cycle is the process by which the phosphate ion passes in very small amounts through the lithosphere from volcanic aeorosols, then to the hydrosphere, where it stays from 20,000 to 100,000 years in the ocean, and finally to biospherere, where rain and erosion helps washing the phosphorus from the rocks into the soil. So, raining is the beginning of the phosphorus´s second cycle, so it is also, the slowest one of the matter cycles that is why the natural total background phosphate levels in several bodies of freshwater range from 0.005 to 0.05 mg/L. Phosphorus remains mostly on land and in rock and soil minerals.
Although abundant on our planet´s sedimentary rock crust and in human body, phosphorus to commercialize is only found in minerals therefore, phosphates mining activity and calcium heating is the only way to get it in its pure elemental form. It is an essential nutrient for plants and animals and a big percentage of the mined phosphorus is used to make fertilizers.
