SCIENCE is life

It ensures that the fertilized egg has a diploid number of chromosomes therefore meiosis brings about the reduction of chromosomes to half the original number both in the male and female Random assortment of genes during meiosis leads to genetic variations amoung offsprings of the same parents. This is why no two individuals can look alike except identical twins Meiosis can lead to a marked gene change (mutation) which can also bring about variations among individuals.

Biogas-slurry is a safe, organic, and nutrient-rich liquid fertiliser, which can be applied directly to crops to increase agricultural productivity. The use of biogas-slurry not only saves money otherwise spent on chemical fertilisers, but reduces the negative effects of such fertilisers on the environment. It is estimated that the application of biogas-slurry may increase productivity as much as 25% when compared to applying manure directly to fields. Biogas is energy rich and is well suited as a source of energy within many areas...............................................

Biogas is produced by bacteria through the bio-degradation of organic material under anaerobic conditions. Natural generation of biogas is an important part of bio-geochemical carbon cycle. It can be used both in rural and urban areas. The composition of biogas and concentration (by component volume) includes: Methane (55-60%), Carbon (iv) Oxide (35-40%), water (2-7%), Hydrogen Sulphide (20-20,000ppm (2%)), Ammonia (0-0.05%), Nitrogen (0.2%), Oxygen (0.2%), Hydrogen (0-1%) General features of biogas are: Energy content 6-6.5KWh/m3 Fuel equivalent 0.6-0.65/oil/m3 biogas Explosion limits 6-12 % biogas in air Ignition temperature 650-750oC Critical temperature -82.5oC Critical pressure 75-89 bar Normal density 1.2 kg/m3 Smell Bad eggs Available at the online bookstore www.morebooks.de  https://www.morebooks.de/gb/search?utf8=%E2%9C%93&q=Ukponmwan+ifueko+oghogho+ Or amazon.com/author/ifuekoukponmwan
