Mercury is a naturally occurring heavy metal that can be transported through the atmosphere and transformed into a toxic‚ organic compound. Anthropogenic and natural determinants can lead to the bioaccumulation of methylmercury in the tissues of aquatic organism‚ leading to non-lethal affects. This chemical can also biomagnify in the tissue of organisms at higher trophic levels (Zillioux et al.‚ 1993). Activities caused by humans such as the burning of fossil fuels‚ coal along with the manufacturing

Practical 2: Observation of mammalian kidney model and tissue slides. Analyzing kidney filtration using simple filtration system Introduction: Kidney is part of mammalian’s body endocrine system. Every mammals have a pair of kidneys that is located at the middle back of the body and symmetrically beside the spine and below the rib cage. A kidney approximately 0.5% of the organism body weight. Every kidney will receive huge amount of blood to enable them to perform important task. The base unit of

BIOMOLECULES 1.What are macromolecules? Give examples. Macromolecules are large complex molecules that occur in colloidal state in intercellular fluid. They are formed by the polymerization of low molecular weight micromolecules. Polysaccharides‚ proteins‚ and nucleic acids are common examples of macromolecules. 2. Illustrate a glycosidic‚ peptide and a phospho-diester bond. (a) Glycosidic bond is formed normally between carbon atoms‚ 1 and 4‚ of neighbouring monosaccharide units. (b) Peptide
