why bacteria as a group show the most extensive metabolic diversity.? |
| Answer» Metabolic diversity\xa0mainly refers to the different\xa0metabolic\xa0strategies that organisms have evolved to obtain energy. An interesting property of some microorganisms is their\xa0metabolic\xa0versatility, which enables them to select their\xa0metabolic\xa0mode according to environmental conditions. The\xa0bacteria\xa0is known to have the\xa0most extensive metabolic diversity\xa0because it is able to extract energy from any carbohydrate which is in its reduced form like sugar. It does that as it has different compounds which have different inorganic or organic reduced electron compounds. | |

All chordates are vertebrate but all vertebrates are not chordates |
| Answer» The characteristic features of the phylum, Chordata, include the presence of a notochord and paired pharyngeal gill slits. In sub-phylum Vertebrata, the notochord present in embryos gets replaced by a cartilaginous or bony vertebral column in adults. Thus, it can be said that all vertebrates are chordates but all chordates are not vertebrates. | |

Explain the condition which create problem in oxygen transport....... |
| Answer» Hypoxic hypoxia occurs when the\xa0PO2\xa0of arterial blood falls. This could occur because inspired\xa0PO2\xa0is lower than normal (high altitude) or it could be due to a respiratory problem (e.g., hypoventilation, diffusion impairment caused by pulmonary edema, ventilation–perfusion mismatch, or anatomic shunt of blood past the gas exchange region). In terms of O2\xa0transport, decreased arterial blood oxygenation (hypoxemia) is the primary limitation, and thus, the problem resides with the respiratory system. Oxygen delivery is abnormal since [O2]a\xa0is less than normal. The circulatory system responds in two ways to improve tissue oxygenation. | |

Reproductive system of erathwor. |
| Answer» Earthworm mating occurs on the surface, most often at night. Earthworms are hermaphrodites; that is, they have both male and female sexual organs. The sexual organs are located in segments 9 to 15. Earthworms have one or two pairs of testes contained within sacs. The two or four pairs of seminal vesicles produce, store and release the sperm via the male pores. Ovaries and oviducts in segment 13 release eggs via female pores on segment 14, while sperm is expelled from segment 15. One or more pairs of spermathecae are present in segments 9 and 10 (depending on the species) which are internal sacs that receive and store sperm from the other worm during copulation. As a result, segment 15 of one worm exudes sperm into segments 9 and 10 with its storage vesicles of its mate. Some species use external spermatophores for sperm transfer. | |

What is alteration of genration |
| Answer» Alternation of generations, also called metagenesis or heterogenesis, in biology, the\xa0alternation\xa0of a sexual phase and an asexual phase in the life cycle of an organism. The two phases, or\xa0generations, are often morphologically, and sometimes chromosomally, distinct.\xa0The fern is an\xa0example of alternation of generations, in which both a multicellular diploid organism and a multicellular haploid organism occur and give rise to the other. ... The large, leafy fern is the diploid organism. On the undersurface of its fronds or leaves, its cells undergo meiosis to create haploid cells. | |

Why species is considerd as basic taxonomic unit? |
| Answer» Taxon is the\xa0basic unit of taxonomy. It is defined as a group of one or more populations of a living being which is seen by taxonomists to form an\xa0unit. A classic example is African elephants from the genus Loxodonta which is widely accepted as a taxon. Species is considered as basic taxonomic category because individuals of a species have same morphological features and they can also interbreed. This is the only taxonomic category which shows these two characteristics. | |

What is herbrium |
| Answer» Herbarium is “a collection of plant specimens which have been dried and pressed and arranged in the sequence of an accepted classifications”. It forms a store house for future use. The preparation of Herbarium involves following steps :(1) Collection of Specimens : It is a field work. For collection one has to get information about the area, habitat, season and the time of collection. There is a requirement of digger for digging roots, scissors for cutting twigs, knife for woody twigs and a pole with a hook for collection.(2) Drying and Pressing : After collection, the plants are dried up by keeping them between the folds of old newspapers. The plants, after (hying, are pressed up by a set of two broads straps.(3) Mounting : The dried specimens are pasted on the herbarium sheets of standard size (29 X 41 cm). The specimens are fixed on the sheets by applying glue or adhesive.The specimens are sprayed with fungicides like 01% solution of mercuric chloride and pesticides like DDT, naphthalene to check fungal growth and insects infections.(4) Labelling : Labelling should be done with mounting. It should bear the botanical name, family, locality, data of collection with the habit of the plant specimen. The name of the collector or the person should also be given.(5) Storage : The sheets are arranged according to classification. They are stored in disinfected metallic cupboards. The information about the collected specimens-is compiled and published in the form of a book. | |

Define hallophley , methenogens , thermoacetophyles? |
| Answer» There are three major known groups of Archaebacteria: methanogens, halophiles, and thermophiles. The methanogens are anaerobic bacteria that produce methane. They are found in sewage treatment plants, bogs, and the intestinal tracts of ruminants. Ancient methanogens are the source of natural gas. Halophiles are bacteria that thrive in high salt concentrations such as those found in salt lakes or pools of sea water. Thermophiles are the heat-loving bacteria found near hydrothermal vents and hot springs.\xa0 | |
| 5283. |
Write four economic importance of methanogens? |
| Answer» Methanogens\xa0are responsible for the methane in the belches of ruminants and in the flatulence in humans.\xa0Methanogens\xa0play a\xa0vital\xa0ecological\xa0role\xa0in anaerobic environments by removing excess hydrogen and fermentation products produced by other forms of anaerobic respiration.\xa0Methanogens\xa0are obligate anaerobic Archaea that\xa0produce energy\xa0from the biosynthesis of methane. These lithotrophic microorganisms are widely distributed in oxygen-free environments and participate actively in the carbon cycle. | |

Define the process of asexual reproduction in Bryophytes? |
| Answer» The main plant body is haploid in bryophytes. The main plant body is called gametophyte because it produces gametes. *** organs are multicellular. Male *** organ is called antheridium and produces biflagellate antherozoids. The female *** organ is called archegonium and produces a single egg. Antherozoids are released into water for fertilization. After fertilization, zygote does not immediately divide meiotically. Zygote produces a multicellular body called sporophyte. Sporophyte is attached to the photosynthetic gametophyte so that it can get nourishment from the gametophyte. Some cells of the sporophyte undergo meiosis to produce haploid spores. The spores germinate to produce gametophyte. | |

What is Green Gland. |
| Answer» Green glands, also called as antennal or maxillary glands, help carry out excretory functions in crayfish. These glands act much like\xa0kidneys\xa0in humans and help crayfish remain healthy by eliminating toxic substances and waste products in their urinary and circulatory systems.\xa0In many higher crustaceans the excretory\xa0glands\xa0are located in the head. They are called antennal\xa0glands\xa0or maxillary\xa0glands, depending on whether they open at the base of the antennae or at the maxillae. If the tubule adjacent to the excretory pore is\xa0green, the\xa0gland\xa0is called a\xa0green gland. | |
