Question :What are the steps of insertion of nucleus into oyster? |
|
Answer» Solution : Following steps are TAKEN for the insertion of nucleus. a. Fitness of oyster for operation The selected oysters for the insertion of nucleus should be healthy and strong enough to overcome the stress during operation. b. Preparation of graft TISSUES The piece of tissue which is inserted inside the mantle is called as 'GRAFT' tissue. The outer edges of these graft squares must be known because nacre secreting cells are found only on the outer surface of the mantle so it is essential to keep the outer surface in contact with the inserted nucleus. c. Preparation of nucleus Any small particle may function as nucleus to initiate the pearl formation but it is reported that calcareous nucleus is the best because the deposition of nacre was found to be more on calcarious nucleus. d. Insertion of nucleus For the insertion of nucleus, oysters are fixed in a desk clamp in the position of right valve facing upward. Mantle folds are SMOOTHLY touched to expose the foot and the main body mass, followed by an incision into the epithelium of the foot and a slender channel into the main mass one graft tissue which functions as a bed for the nucleus. e. Post operation care NUCLEATED oysters are placed into cages and suspended into sea water and attached with floating rafts to a depth of 2 to 3 metres for about 6 to 7 days to recover from the shocks due to operation. This period of 6 to 7 days is known as 'Recovery period'. About 3000 to 3600 nucleated oysters are kept in different cages suspended in sea water at 2 to 3 meters depth for 3 to 6 years and undisturbed except at the time of clearing and inspection. iv. Harvesting of pearl Pearls are harvested in the month of December to February which may slightly vary ACCORDING to climatic conditions. After the completion of 3 years of the insertion of nucleus, pearl oysters are harvested from the sea and the pearls are taken out from the shell. v. Clearing of pearls After taking out the pearls from the oysters shell they are washed properly, cleared with the soap solution. |

Question : What are the stages involved in rearing of chicken? |
|
Answer» Solution :Stages involved in rearing : There are some steps involved in rearing of chicken. 1. Selection of the best layer : An active intelligent LOOKING bir, with a bright comb, not obese should be selected. 2. Selection of eggs for hatching : Eggs should be selected very carefully.Eggs should be fertile, medium sized, dark brown shelled and freshly laid eggs are preferred for rearing.Eggs should be washed, cleaned and dried. 3. Incubation and hatching : The maintenance of newly laid eggs in optium condition TILL hatching is called incubation. The fully developed chick emerges out of eggafter an incubation period of 21 - 22 days.There are two types of incubation namely natural incubation and artificial incubation.In the natural incubation method,only a limited number of eggs can be incubated by a mother hen.In artificial incubation, more number of eggs can be incubated in a chanber(Incubator). 4. Brooding : Caring and management of yound chicks for 4 -6 weeks immediately after hatching is called brooding.It can ALSO categorized into two types namely natural andartificial brooding. Housing of poultry : To protect the poultry from sun, rain and predators it is necessary toprovide housing to poultry. Poultry house should be mositure-PROOF, rat proof and it should be easily cleanable and durable.

Question : Write any three significance of mitosis. |
|
Answer» Solution :Exact copy of the parent cell is produced by mitosis (genetically identical). 1. Genetic stability-daughter cells are genetically identical to parent cells. 2. Growth-As multicellular organisms grow, the number of cells making up their tissue increases. the new cells must be identical to the existing ones. 3. Repair of TISSUES-Damaged cells must be replaced by identical new cells by mitosis. 4. Asexual reproduction- A sexual reproduction results in offspring that are identical to the parent. example YEAST and AMOEBA. In flowring plants, structure such as bulbs, corms, TUBERS, rhizomes and runners are produced by mitotic division. when they separate from the parent, they form a new individual. The production of large number of offsprings in a short period of time, is possible only by mitosis. in genetic engineering and biotechnology, tissues are GROWN by mitosis (i.e., in tissue culture). |

Question : What are the rules of binomial nomenclature ? |
|
Answer» Solution :Binomial nomenclature naming system was given by biologists all over the WORLD. This naming system using a two word FORMAT was found convenient. Other universal rules of nomenclature are as follows: (1) BIOLOGICAL names are generally in Latin an written in italics. They are Latinised or derived irrespective of their origin. (2) The first word in a biological name represent the genus while the second component denotes the specific epithet. (3) Both the words in a biological name, when handwritten are separately underlined or printed in italics to indicate their Latin origin. (4) The first word denoting the genus starts with a capital letter while the specific epithet starts with a small letter. If can be illustrated with the example of Mangifera INDICA. Name of the author appears after the specific epithet i.e., at the end of the biological name and is written in an ABBREVIATED form eg. Mangifera Indica Linn. It indicates that this species was first described by Linnaeus. |

Question :What are the products of bee keeping? |
| Answer» Solution :Products of BEE keeping and their ECONOMIC importance The chief products of bee keeping industry are honey and bee wax. Honey is the healthier substitute for sugar. The major constituents of honey are: levulose, dextrose, maltose, other sugars, enzymes, pigments, ash and water. It is an aromatic sweet material derived from nectar of plants. It is a natural food, the smell and taste DEPENDS upon the pollen taken by the honey bee. It is used as an antiseptic, laxative and as a SEDATIVE. It is generally used in Ayurvedic and Unani SYSTEMS of medicine. It is also used in the preparation of cakes, breads and biscuits. Bee wax is secreted by the abdomen of the worker bees at the age of two weeks. The wax is masticated and mixed with the secretions of the cephalic glands to convert it into a plastic resinous substance. The resinous chemical substance present in the wax is called propolis which is derived from pollen grains. The pure wax is white in colour and the yellow colour is due to the presence of carotenoid pigments. It is used for making candles, water proofing materials, polishes for floors, furniture, appliances, leather and taps. It is also used for the production of comb foundation sheets in bee keeping and used in pharmaceutical industries. | |

Question : Mention some physiological changes occuring during senescence. |
|
Answer» Solution :Morphological and Anatomical changes during abscission: Leaf abscission TAKES place at the base of petiole which is marked internally by a distinct zone of few layers of THIN walled cells arranged TRANSVERSELY. This zone is called abscission zone or abscission layer. An abscission layer is greenish-grey in colour and is formed by rows of cells of 2 to 15 cells thick. The cells of abscission layer separate due to dissolution of middle LAMELLA and primary wall of cells by the activity of enzymes pectinase and cellulase resulting in loosening of cells. Tyloses are also formed blocking the conducting vessels. Degrading of chlorophyll occur leading to the change in the colour of leaves, leaf detachment from the plant and leaf fall. After abscission, outer layer of cells becomes suberized by the DEVELOPMENT of periderm. |
