HSC Biology – Blueprint of Life 4. The structure of DNA can be changed and such changes may be reflected in the phenotype of the affected organism. The phenotype of an organism is its total appearance determined during development by an interaction between its genetic make-up (genotype) and the environment. A genome is all of the genetic material (DNA) within a cell and is specific to each organism. Genomes influence nearly all the traits or phenotypes. The phenotypic appearance is therefore

2.3 Chemistry of water Water is a polar molecule The shape of a water molecule and its polarity make hydrogen bonding possible, A hydrogen bond is a weak attraction between a slightly positive hydrogen atom and a slightly negative atom. (They are partial charging) * Can occur between atoms of different molecule or within the same molecule * A single hydrogen bond is easily broken while multiple hydrogen bonds are collectively quite strong. * Help to maintain the proper structure

Q1 A cell’s genetic information or genome or DNA, either a single DNA molecule in prokaryotes or multi DNA molecules in eukaryotes always consist of chromosomes. In humans, a typical cell has about 3 meters of DNA which has to be copied and then this copy has to be separated during cell division. This can be done just because the DNA molecule can be packed into chromosomes (chromo means coloured). Every species has certain number of chromosomes in each nucleus, for example humans have 46 chromosomes

COMPARATIVE TEST Health Drinks Making Milk Richer The concepts of health and energy have perhaps never been as popular—or pursued/coveted— as they are now. (After all, even a leading burger chain is desperately seeking ‘nutritional’ status for its fare.) With market rivalries becoming an intense affair, brand strategists and marketers are eager to refresh their brand’s positioning and image. More often than not, it is the ‘health’ tag that becomes their ‘open sesame’ to the consumer universe

According to the Britannica Encyclopedia, an allusion “is an implied or indirect reference to a person, event, or thing or to a part of another text. Allusion is distinguished from such devices as direct quote and imitation or parody. Most allusions are based on the assumption that there is a body of knowledge that is shared by the author and the reader and that therefore the reader will understand the author’s referent.” "allusion".
