Define mososome in detail. |
|
Answer» Mesosomes are extensions of plasma membrane into the cell in the form of vesicles, tubules and lamellae.These are of two types : Septal mesosome and Lateral mesosome.(a) Septal mesosome may be involved in cell wall formation, chromosome replication and distribution of chromosomes to daughter cells, secretory processes and increase in plasma membrane surface area and enzymatic content.(b) Lateral mesosome contains respiratory enzymes often called chondroid. Thanks.. Sorry I mistakenly write mesosome as "mososome". It might be mesosomeDefinition of mesosome. : an organelle of bacteria that appears as an invagination of the plasma membrane and functions either in DNA replication and cell division or excretion of exoenzymes |

What is plasmalemna in protozoa |
| Answer» Protozoa\xa0are single-celled eukaryotes (organisms whose cells have nuclei) that commonly show characteristics usually associated with animals, most notably mobility and heterotrophy. They are often grouped in the kingdom Protista together with the plant-like algae and fungus-like water molds and slime molds.\xa0The\xa0plasma membrane\xa0is a barrier between the cell cytoplasm and the outside liquid environment. Some substances, such as oxygen, readily pass through the membrane by diffusion (passive transport), while others must be transported across at the expense of energy (active transport). | |

All living phenomenon are due to underlying interactions.Explain. |
| Answer» All living phenomena are due to underlying interactions. Properties of tissues are not present in the constituent cells. Similarly, properties of cellular organelles are not present in the molecular constituents of the organelle but arise as a result of interactions among the molecular components comprising the organelle. These interactions result in emergent properties at a higher level of organization. This phenomenon is true in the hierarchy of organisational complexity at all levels. | |

Explain the two different ways of biodiversity conservation |
| Answer» There are two basic approaches for the conservation of biodiversity\xa0\tEx situ conservation (off-site\xa0conservation)\tIn situ conservation (on-site conservation)In situ conservation, It is the conservation and protection of biodiversity in its natural habitat.\tIt helps in recovering population in the surroundings where they have developed their distinctive features.\tExample\xa0National parks, biosphere reserves, wildlife sanctuaries.Ex situ conservation\xa0It is the conservation of selected rare plants and animals in places outside their natural habitat\tIt helps in recovering population or preventing their extinction under conditions that closely resemble their natural habitats.\tExample\xa0Botanical gardens, zoological parks, wildlife safari parks, gene banks, etc. | |

Define - (1)PLASMOGAMY (2) DIKARYON (3) DIKARYOPHASE (4) ISOGAMOUS (5) ANISOGAMOUS (6) OOSOGAMOUS |
|
Answer» \tPLASMOGAMY :\xa0Plasmogamy is a stage in the sexual reproduction of fungi, in which the cytoplasm of two parent cells (usually from the mycelia) fuses together without the fusion of nuclei, effectively bringing two haploid nuclei close together in the same cell.\tDIKARYON :\xa0The\xa0dikaryon\xa0is a nuclear feature which is unique to some fungi. The green alga Derbesia has been long considered an exception, until the heterokaryotic hypothesis was challenged by later studies. Compatible cell-types can fuse cytoplasms (plasmogamy).\tDIKARYOPHASE :\xa0\xa0the phase of the life cycle of a fungus (as the rusts) characterized by the dikaryotic condition.\tISOGAMOUS :\xa0Many algae and some fungi have\xa0isogamous\xa0gametes. In most sexual reproduction, as in mammals for\xa0example, the ovum is quite larger and of different appearance than the sperm cell. This condition is called anisogamy. "isogamy."\tANISOGAMOUS :\xa0Anisogamy\xa0(also called heterogamy) is the form of sexual reproduction that involves the union or fusion of two gametes, which differ in size and/or form. (The related adjectives are\xa0anisogamous\xa0and anisogamic). Hi Sia, please tell how you study to achieve your aim Thanks!!☺☺ |

What is embryological origin of digestive tract, tooth and pancreas? |
| Answer» The gastrointestinal tract (GIT) arises initially during the process of gastrulation from the endoderm of the trilaminar embryo (week 3) and extends from the buccopharyngeal membrane to the cloacal membrane. The tract and associated organs later have contributions from all the germ cell layers.While crown formation is accomplished during\xa0embryonic\xa0development,\xa0tooth\xa0root formation occurs in mice molar\xa0teeth\xa0at postnatal stages and lasts for up to three weeks. During root formation, cemento blasts are formed from the mesenchymal\xa0tooth\xa0compartment and secrete cementum, which surrounds the forming\xa0tooth\xa0root.As part of\xa0embryonic\xa0development, the\xa0pancreas forms as two buds from the fore gut, an\xa0embryonic tube that is a precursor to the gastrointestinal tract. It is therefore of endodermal\xa0origin.\xa0Pancreatic development begins with the formation of a dorsal and ventral\xa0pancreatic\xa0bud. | |

Why do the wild animals rarely reproduce in zoo? |
|
Answer» Sia.. Pls just hear my ans i think...In zoo they are not able to meet/find their matting partner. The area for free movement of wild animals is reduced which retard reproductive capacity of certain wild animals like rhino, tiger, bison, etc. This is one of the reasons why the wild animals in the zoo rarely reproduce. |

What are the layers in basal body of flagelle |
| Answer» The\xa0flagellum\xa0of E. coli consists of three parts, filament, hook and\xa0basal body, all composed of different proteins. The\xa0basal body\xa0and hook anchor the whip-like filament to the cell surface. The\xa0basal body\xa0consists of four ring-shaped proteins stacked like donuts around a central rod in the cell envelope.\xa0A bacterial\xa0flagellum\xa0has 3 basic\xa0parts: a filament, a hook, and a basal body. 1) The filament is the rigid, helical structure that extends from the cell surface.\xa0The\xa0basal body\xa0of a bacterial\xa0flagellum\xa0is a rod and a system of rings embedded in the cell envelope. ... The rod is a major component of the\xa0flagellar basal body\xa0and it spans the bacterial periplasm. The L and P rings are not found in Gram-positive bacteria. | |

Discuss how classification system have undergone several changes over a period of time |
| Answer» They change because we continue to learn. For example, when we learned how to extract DNA and test it, we discovered we were wrong about how we’d classified many plants and animals. As we’ve learned more about mental illness, we’ve had to reclassify.Classification helps us learn, but we should always understand that the present system is temporary. We’ll continue to change it as we learn more. Because there’s always more to discover, our classification systems will continue to change. | |
