    I am very sorry! Protein was absent since colour with biuret test was blue. For Question 28 the correct option was C (with a straight line through origin, since both volumes are the same). Thank you for correcting me! :)

    food tests, a table was given with positive results with benedict's solution and ethanol (plus water) and negative result with Biuret solution, and it was asked that which row shows the correct substances' presence. Protein was obviously absent and reducing sugars were also present. However...

    It said that there were base pairs within part of the chain, whereas in DNA there are base pairs throughout the entire length. Also, in DNA there are two polynucleotides, whereas the description was about one polynucleotide. :)

    For Q2 i wrote C, which is probably wrong. The rest of your answers match mine! :) Although in Q6 i think fatty acids were also not present (I just realised it now, i also selected the option with absence of proteins and presence of reducing sugar and fatty acids).

    Biology Paper 12 Repeated and New Questions

    About tRNA the second statement described the structure of a tRNA molecule, which was essentially correct (a polynucleotide chain in which there are some base pairs within the chain). Apoplastic movement invloves cohesion of water, which occurs in walls of xylem (cohesion with cellulose cell...

    As part of chemistry, Hydrogen bonds are a type of covalent bond (coordinate bond), but in the scope of Biology, they are not strictly considered as covalent bonds. You should just know that peptide bonds are covalent and strongest bonds in polypeptides, then disulfide, then ionic, then hydrogen...

    Due to increased amounts of dust, less sunlight reaches producers. Due to insufficient sunlight, the producers die. As the populations of producers decreases, the populations of the consumers will also decrease (food chain). As there are more dead organisms, there will be more decomposers (more...

    This is what Wikipedia says about HbCO2: When carbon dioxide binds to hemoglobin, carbaminohemoglobin is formed, lowering hemoglobin's affinity for oxygen via the Bohr effect Therefore, at low oxygen partial pressures and hight CO2 partial pressures, CO2 combines with Hb to give HbCO2 and this...
