This question actually refers to body parts: otoliths are small structures in your inner ears (in the semicircular canals, so this part is correct) that shift when you move - to help you sense your body position (so this part is also true).
But they're not exactly stones - they are small particles, so that's why the statement is false.
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.
Answer:
Water
Explanation:
Water is essential to human life. Hence, human settlements tend to crop up near water sources such as rivers. This is particularly evidence in Africa, which has many quite dry regions.
Explanation:
The modernization theory explains the process of transforming from traditional society to modern society and consist of the following processes-
(1) Technological advancement - Here, the traditional knowledge is replaced with modern techniques and scientific information proves the things.
(2) Development of agriculture - Since agriculture provides major source for advancement, new machines are brought in use that will increase the productivity to gain more benefits. There will a change from subsistence type of farming into modern farming with modern tools and technology
(3) Urbanization - due to uncontrolled migration from rural to urban, there is increase in the rate of urbanization
(4) Industrialization - Now human are replaced with machines
(5) Telecommunication - it includes digitalization the economy, better news broadcasting, entertainment etc.
All these processes have similarities and differences since they are all interrelated. Similarity is that all these processes lead to increase in profit that would further help in increasing per capita income and thus more productivity and better development. You can take an example of US economy which is highly advanced and has all these sub processes going on there .
