Different living organisms tide over very low or very high temperature conditions differently. For E.g., i) Encystment It involves the formation of a hard and chitinous protective coat called cyst, around the body. It is commonly seen in amoeba, euglena. ii) Hibernation (winter sleep) Some animals ..

Role Of Hormones As Messengers And Regulators - Hormones are informational molecules. They are secreted in response to changes in the environment inside or outside the body. These are released into the extracellular fluid, where they are diffused into the blood stream. The latter carries ..

>The repressor protein binds with the operate gene, RNA polymerase cannot be allowed and hence structural genes get switched off. The repressor protein is kept in an active state by the inducer which is usually the substrate molecule. The repressible operon has the same components as in inducible o..

Gibberellins have been shown to be effective in breaking the dormancy in potato tubers and in tree buds in winter. Cytokinins have been found to be effective in breaking the dormancy of seeds. They also promote the germination of the seeds. The cytokinins substitute the red light requirement..

Dams contribute enormously to deforestation and the loss of biological diversity. They can also result in potentially huge accidents during disasters like earthquakes. The embracing of centralized mega water management and regulation has also led to two more criticisms. The politicizat..

. Such an oncogenic transformation requires activation of the oncogenes by carcinogens. Normal cell growth is under the control of genes, which regulate cell proliferation, differentiation and survival. Alterations in these genes lead to oncogenic transformation. Cancer is cause..
