Don’t confuse this element with another bi- which means "two".
The most important things in life are not things.
2. The examination of vital functions; such as, respiration, heart beat, and pulse to determine whether an individual is alive.
The biosensor can also be used in the laboratory or placed within the body.2. A device to monitor and to transmit information about biological processes. such as the effect of motion on an animal in space: After many trials, the scientists developed a biosensor that worked in the weightlessness of the space capsule.
2. Relating to, or involving, an interaction or combination of social and biological factors.
2. A nutrient-rich organic material, or byproduct, resulting from the treatment of municipal wastewater.
Biosolids can be safely recycled; for example, for fertilizers.
Biosolids contain nitrogen and phosphorus along with other supplementary nutrients in smaller doses; such as, potassium, sulfur, magnesium, calcium, copper, and zinc.
Soil that is lacking in these substances can be reclaimed with biosolids use. The application of biosolids to land improves soil properties and plant productivity, and reduces dependence on inorganic fertilizers.
There are some obstacles to sewage sludge reuse because in modern societies; especially, with sewage biosolids reuse in agriculture. Even if problems of pollutant contamination (heavy metals, organic contaminants, pharmaceuticals) and public opinion were resolved, considerable obstacles would still remain.
Cities and intensive livestock production units both lead to localized surpluses of nutrients. Biosolids have relatively low nutrient content compared to high water content.
2. The use by certain animals of echoes of sounds they produce to locate objects in the perceptual field as with bats as they move around.
2. A species defined primarily on biological characteristics: "An interesting fact of biospecies is that it establishes the likeness of DNA of people, or groups of people. One technique is using genetic fingerprinting."
