Discussion: For this week, we did the experiment under family of cereal which was about to investigate the effect of different alkaline solution on the quality of yellow wet noodles. There were four different formulations that we used. According to the table A in the procedure, it stated that for formulation 1, we were using…

Biosynthesis of Silver nanoparticles utilizing Red algaePortieria hornemannii Abstraction Nanotechnology is regarded as one of the most wanted Fieldss of research in the present scientific universe. The applications of nanoparticles scopes from pharmaceuticals, Even though the synthesis of nano atoms can be done by agencies of physical, chemical and green methods, owing to the eco…

This experiment examines cell membrane permeableness, osmosis and membrane electromotive forces ; all of which are of import in understanding how cells are affected by their environment. The motion of H2O across membranes is of import for cell volume and therefore the volume of extracellular compartments. The mechanisms for solute conveyance are indispensable in keeping…

The qualities of diamond are heavily influenced by its composition, crystal structure, and mechanical, thermal, and electromagnetic properties. The composition is the most influential factor among these dependencies. The crystal structure represents the repeating pattern of diamond’s composition, and the properties are determined by molecular interaction, which in turn is influenced by composition. Thus, the…

Both Diamond and Graphite are different forms of carbon, known as allotropic forms. Despite sharing the same element, they display contrasting properties. Diamond is exceptional in conducting heat but lacks conductivity in electricity, whereas graphite struggles with thermal conduction but excels in electrical conduction. This variation in properties is a result of the distinct arrangement…

An ester was synthesized during an organic reaction and identified by IR spectrometry and boiling point. Acetic acid was added to 4-methyl-2-pentanol. which was catalyzed by sulphuric acid. This produced the coveted ester and H2O. After the ester was isolated a percent output of 55. 1 % was calculated from the 0. 872 g of…

Antigens usually bind to the side chain of the antigen binding site of the antibody, which may either be a protein, polypeptide or lipid. Antigens and antibody interactions are mediated by non-covalent bonds such as electrostatic forces, van der Waals forces and hydrophobic forces. Binding mediated by this type of bonds produces a reversible reaction….
