Why starch produce blue colour with iodine but cellulose can not? |
|
Answer» Cellulose is derived feom O- glucose units, which condensed through beta (1->4) - glycosidic bond. This give cellulose to be a straight polymer therefore, it cannot coil around iodine to produce blue color as starch does. Coz starch has helixes which can hold I² but cellulose doeanot have helixes |

nitogen fixation and nitrogen cycle |
|
Answer» Hi The nitrogen cycle is the process by which nitrogen is converted between its various chemical forms.The features of the nitrogen cycle are-(i)Nitrogen fixation-Atmospheric nitrogen must be processed, to be used by plants.(ii)Assimilation-Plants can absorb nitrate or ammonia from the soil via their root hairs. If nitrate is absorbed, it is first reduced to nitrite and then ammonia.(iii)Ammonification-Bacteria, or fungi in some cases, convert the organic nitrogen into ammonium, a process called ammonification.(iv)Nitrification-Conversion of ammonia to nitrate is performed primarily by soil-living bacteria and other nitrifying bacteria.(v)Denitrification- Denitrification is the reduction of nitrates back into the largely inert nitrogen gas, completing the nitrogen cycle which is performed by\xa0Clostridium\xa0in anaerobic conditions. |

What does Hermaphrodite means ? |
| Answer» Many invertebrates and a significantly smaller number of vertebrates are hermaphrodites. A hermaphrodite possesses both male and female reproductive organs during their life span. Some of these animals self-fertilize, while others require a partner. It is a condition which enables a form of sexual reproduction in which both partners can act as the "female" or "male". Examples: Snails,worms and about 21 families of fish are Hermaphrodites. Refer this link for more explanation: | |

Explain the mode of hormobe action through extracellular receptor with the help of suitable example |
|
Answer» what is oxygen dissociation curve? The hormone insulin provide a good example to explain the mode of human action through the extracellular receptors. The membrane bound receptor of insulin is a protein consisting of four subunits : the two a-subunits and two p-subunits. The following are the steps in this mechanism :(a) Binding to the receptor : Insulin binds with the outer a-subunits of the receptor. This causes a structural change in the p-subunits, to become an activated kinase, which promotes phosphorylation.(b) Second Messengers : The hormonal control of cell function is done through adenylate cyclase. The hormone receptor complex does not directly stimulates adenylate cyclase. It is done through a transducer G protein. The hormone receptorcomplex induces the release of GDP from the G protein. It makes phosphatidylinositol which activates other processes.© Amplification of signal : Mediates amplifier signals. The P-subunit activates DG and IP3 with second messenger. Some hormones use secondary messenger cAMP. Adenyl cyclase is amplifier. It changes Adenyl cyclase into ATP and then into cAMP. Adrenaline binds to receptors in liver or muscles cells which changes shape and binds to G protein. Then it binds to GTP and activates adenyl cyclase. This adrenaline releases 100 million moles of glucose (C5Hi2Ofi) in one or two minutes. |

Define haplontic life cycle????? |
| Answer» The haplontic life cycle is a type of life cycle with a dominant haploid stage. The zygote of the organisms with a haplontic life cycle undergoes meiosis immediately after karyogamy in a process called the zygotic meiosis. Hence, the organism ends up in a haploid stage. The mitotic cell division of these haploid cells allows the formation of a multicellular organism with a mass of haploid cells. | |
