What are the advantages of the Five Kingdom classification? |
|
Answer» It helps us to learn about similar types of organism in a same group.as it reduces the loads over us The 5 kingdom classification is largely the most accepted system of modern classification mainly because of the phylogenetic placing of different groups of living organisms.This system of classification looks more scientific and natural.There is far less overlap and confusion in this system, as compared to the original two kingdom classification.Grouping of all unicellular eukaryotes under the kingdom Protista has solved many problems, particularly related to the position of organisms like Euglena.Separation of prokaryotes into an independent kingdom is justifiable because they differ from all other organisms in their general organizationThe five-kingdom classification gives a clear indication of cellular organization and modes of nutrition, the characters which appeared very early in the evolution of life. |

Mention the process of anaerobic respiration in muscle cell? |
| Answer» Anaerobic respiration is also used by multi-cellular organisms, like us, as a temporary response to oxygen-less conditions. During heavy or intensive exercise such as running, sprinting, cycling or weight lifting, our body demands high energy. As the supply of oxygen is limited, the muscle cells inside our body resort to anaerobic respiration to fulfill the energy demand. | |

Name the final acceptor of electron in ETC? |
| Answer» Electron transport system is an integral part of the cellular respiration. Electrons are passed to oxygen through electron carriers which results in the formation of H2O. Electron carriers fall into three categories here.(A) Electron AcceptorsNAD (Nicotinamide adenine dinucleotide) and FAD (Flavin adenine dinucleotide) both accept electrons and get reduced to NADH+H+\xa0and FADH2.This occurs during process glycolysis, oxidative decarboxylation of pyruvic acid and Krebs’ cycle.(B) Respiratory Coenzyme ComplexesComplex I\xa0- NADH dehydrogenase: It oxidises NADH+ H+\xa0and receives electrons or H+\xa0ions from NADH+H+. These electrons are then passed to the mobile electron carrier ubiquinone.Complex II -\xa0Succinate dehydrogenase: It oxidises FADH2\xa0and the release electrons are sent to the mobile electron carrier ubiquinone.Complex III -\xa0Cytochrome b + cytochrome c1: Cytochrome bc1\xa0complex accepts electrons from ubiquinone and passes them to the mobile electron carrier cytochrome c.Complex IV -\xa0Cytochrome a, a3: Complex IV accepts electrons from cytochrome c and passes them to oxygen. Oxygen acts as a final hydrogen or electron acceptor. Oxygen when combines with two protons it forms a molecule of water.(C) Mobile Electron CarriersUbiquinone: It is a carrier between complex I and complex II. It transfers electrons from NADH to complex III.Cytochrome c:\xa0It is a carrier between complex II and complex III. It transfers electrons to complex IV. | |

How will the wavelength of light effect the magnification of microscope |
| Answer» The\xa0wavelength\xa0of the\xa0light\xa0and the\xa0magnification\xa0of the\xa0microscope\xa0is inversely proportional which means the longer the\xa0wavelength, the less the\xa0magnification\xa0and vice versa. The\xa0magnification\xa0defines the how closer the object is viewed.\xa0Microscope resolution is also impacted by the\xa0wavelength\xa0of light being used to illuminate the specimen. Longer\xa0wavelengths\xa0of light offer less resolution than short\xa0wavelength\xa0illumination. ... As light slows down the\xa0wavelength\xa0gets shorter and yields better resolution. | |

How are proteins retained after ultrafiltration |
| Answer» Ultrafiltration\xa0(UF) is a membrane filtration\xa0process\xa0similar to Reverse Osmosis, using hydrostatic pressure to force water through a semi-permeable membrane. Suspended solids and solutes of high molecular weight are retained, while water and low molecular weight solutes pass through the membrane.\xa0Ultrafiltration\xa0is an effective means of reducing the silt density index of water and removing particulates that can foul reverse osmosis membranes.\xa0Ultrafiltration\xa0is frequently used to pretreat surface water, seawater and biologically treated municipal water upstream of the reverse osmosis unit. | |

Prokaryotes lacks cholestorol so what they contain |
| Answer» In\xa0prokaryotes,\xa0which lack\xa0a nucleus, cytoplasm simply means everything found inside the plasma membrane. One major component of the cytoplasm in both\xa0prokaryotes\xa0and eukaryotes\xa0is\xa0the gel-like cytosol, a water-based solution that\xa0contains\xa0ions, small molecules, and macromolecules.\xa0Prokaryotic cells\xa0are surrounded by a plasma membrane, but they\xa0have no\xa0internal membrane-bound organelles within their cytoplasm. The absence of a nucleus and other membrane-bound organelles differentiates\xa0prokaryotes\xa0from another class of organisms called eukaryotes. | |

What was neil contribution to photosynthesis |
| Answer» van Niel, C. B.\xa0Cornelis Bernardus van Niel\xa0was a Dutch microbiologist whose experiments with bacteria helped explain how photosynthesis occurs in plants. Sulfur bacteria particularly interested van Niel, because there was a controversy in the early 1900s concerning the bacteria.\xa0Jan Baptista\xa0van Helmont\xa0(1580-1644) partially discovered the process of\xa0photosynthesis. He grew a willow tree in a weighed amount of soil. ... As the weight of the soil had hardly changed,\xa0van Helmont\xa0concluded that plant growth cannot only be due to minerals from the soil.\xa0Photosynthesis was partially discovered in the 1600\'s by\xa0Jan Baptista van Helmont, a Belgian chemist, physiologist and physician. | |

Capaleris |
| Answer» Capillaries\xa0are very tiny blood vessels — so small that a single red blood cell can barely fit through them. They help to connect your arteries and veins in addition to facilitating the exchange of certain elements between your blood and tissues.\xa0Capillaries are the smallest of the body\'s blood vessels. They are only one cell thick, and they are the sites of the transfer of oxygen and other\xa0nutrients\xa0from the bloodstream to other tissues in the body.\xa0During early embryonic development new\xa0capillaries\xa0are\xa0formed\xa0through vasculogenesis, the process of blood vessel\xa0formation\xa0that occurs through a de novo production of endothelial cells which then\xa0form\xa0vascular tubes. | |

Name the distingh pathway of water transport in plant |
| Answer» Plant transport\xa0systems move energy from leaves and raw materials from roots to all their parts. The xylem (tissue) moves water and minerals obtained from the soil to all other parts of the\xa0plants.\xa0The\xa0symplast pathway\xa0is where water moves between cytoplasm/vacuoles of adjacent cells. However, the\xa0apoplast pathway\xa0can only take water a certain way; near the xylem, the Casparian strip forms an impenetrable barrier to water in the cell walls, and water must move into the cytoplasm to continue.\xa0Overall,\xa0water\xa0is\xa0transported\xa0in the\xa0plant through\xa0the combined efforts of individual cells and the conductive tissues of the vascular system. ... It is carried upward\xa0through\xa0the xylem by transpiration, and then passed into the leaves along another\xa0water\xa0potential gradient. | |

What would happen if solutions is poorly aerated |
| Answer» \xa0If nutrient solution is poorly aerated in hydroponics, the roots cannot access oxygen. In case of plants in soil, roots access oxygen through pores in soil. But in cases of plants in hydroponic treatment, oxygen has to be supplied to the roots for respiration artificially i.e. through the nutrient solution. Hence, if this solution is poorly aerated, the roots as well as the entire plant will die. | |

Write the functions of the different parts of the nephrons. |
| Answer» Nephrons are structural and functional units of kidneys. They are long, colied tubular structures. Each nephron shows the following parts - Malpighian body, proximal convoluted tubule, loop of Henle, distal convoluted tubule and collecting duct. The Malpighian body shows a cup-shaped Bowman\'s capsule, in which is present a tuft of capillaries called glomerulus.Nephrons are the basic filtration units in kidneys. They filter the blood and form and concentrate urine. Useful substances are reabsorbed by the nephrons and put back into circulation. | |

Explain counter current mechanism? |
| Answer» The flow of the glomerular filtrate in the two limbs of Henle’s loop and the vasa recta is in a counter-current pattern.NaCl is transported by the ascending limb of Henle’s loop which is exchanged with the descending limb of the vasa recta.NaCl is returned to the interstitium by the descending portion of the vasa recta.Similarly, minute quantities of urea enter the thin segment of Henle’s loop which is transported back to the interstitium by the collecting tubule.The counter-current pattern and the proximity between the Henle’s loop and the vasa recta help to maintain the osmolarity in the inner medullary interstitium, i.e. 300 mOsmoiL−1 in the cortex and 1200 mOsmoiL−1 in the medulla.This process is called the counter-current mechanism. | |

What is wilting |
| Answer» Wilting is the loss of turgidity of leaves and other soft aerial parts of a plant causing their drooping, folding and rolling. Wilting is of three types :(a) Incipient wilting: There are no external symptoms of wilting but the mesophyll cells have lost sufficient water due to transpiration being higher than the(b) Temporary wilting : It is the temporary drooping down of leaves and young shoots due to loss of turgidity during noon. It can be corrected only after the rate of transpiration decreases accompanied by replenishment of water around root hairs.(c) Permanent wilting : It is that state in the loss of turgidity of leaves when they do not regain their turgidity even on being placed in a suitable atmosphere | |
