The rock found in the riverbed that is smooth is from the result of weathering of water in the river and erosion. The rock deep underground was most likely a product of erosion. The dirt and ground above it were eroded and displaced there to cover the rock.
Answer: photosynthesis
Explanation: In photosynthesis, carbon dioxide and water reacts in the presence of sunlight to produce glucose and oxygen. In photosynthesis, oxygen is released in to the atmosphere while the glucose formed is stored in the plant as food. No carbon is introduced in to the atmosphere during respiration rather carbon dioxide is used up.
In respiration, glucose is broken down in the presence of oxygen to produce carbon dioxide, water and energy. Carbon is introduced in to the atmosphere in form of carbon dioxide.
In forest fires and burning of fossil fuels, wood and fuels burn in sufficient supply of oxygen liberates carbon dioxide (CO2) but when it burns in insufficient supply of oxygen, it liberates carbon monoxide (CO). In both cases carbon is introduced in to the atmosphere in form of carbon dioxide or carbon monoxide.
This is because some of the trisomies (one extra chromosome, three instead of two) are fatal, births cannot survive.
Theoretically, trisomies can occur with any chromosome, but often result in miscarriage.
The types of autosomal trisomy that survive to birth in humans are:
Trisomy 8 or Warkany syndrome 2
Trisomy 9
Trisomy 13 or Patau syndrome
Trisomy 18 or Edwards syndrom
Trisomy 21 or Down syndrome.

Answer: Mineralization
Explanation: Phosphorous cycle moves through the rocks, water, soil, sediments and organisms.
The weathering of rock releases phosphate ions and other minerals. Plants take up the phosphate from the soil. Phosphorous is present in the form of organic phosphate which is broken down by the help of microorganism in the form of inorganic phosphate.
This process is known as mineralization.
