Along the way, this involves several additional goals. Chapter 1. The first objective is to determine whether floral dimorphism is translated into gynodioecism in Lauraceae, the phylogenetic relationship with other breeding systems in Lauraceae. Results would provide steady evidence…

  • Vicia Faba Seeds Essay

    40 “Yates” Vicia Faba seeds were selected and measured using a millimetre ruler, ensuring that all selected seeds were kept within a size range of 3mm in diameter. Each one of the 8 pots was filled with 8dm3 of soil and given a label using the marking pen, indicating the concentration of gibberellic acid that would be poured into it. 5 Vicia Faba seeds were placed in each pot and buried into the soil at a consistent depth of 1cm. The distance between each seed and adjacent seeds was kept at a…

  • Negative Consequences Of Lead/Acid Battery

    The available technology points toward the use of lead/acid batteries to supply the power for ZEVs. The negative consequences associated with lead/acid batteries are numerous. For example, lead/acid batteries contain a large amount of lead. When the life of the battery is lost, the disposal of the lead within the battery must be dealt with appropriately. An analysis by researchers at Carnegie-Mellon found that the mass production of electric cars using lead/acid battery packs would exponentially…

  • Malnutrition Is A Solution To Genetically Modified Food?

    that make people suspicious. Many of the concerned scientists and anti-GM groups are in fact asking for control and regulations on these crops for as it stands they are considered a free-for- all-activity. There have been reports for example of GM plants that skip the field trials .One such example is in 2006 when rice with bacteria bacillus thuringienis found its way to European supermarkets without field trials. The rice created in a bid to offer resistance to insects had not yet been approved…
