Discuss the advantages of tissue culture over the natural method of vegetativepropagation. Answer fast |
|
Answer» The new plantlets can be grown in a short amount of time. Only a small amount of initial plant tissue is required. The new plantlets and plants are more likely to be free of viruses and diseases. The process is not dependant on the seasons and can be done throughout the year. You need only a relatively small space to PERFORM the process (ten times the plants in one-tenth of the space). On a larger SCALE, the tissue culture process HELPS to supply the consumer market with new subspecies and variety. People looking to cultivate challenging plants such as specific breeds of orchid find more success with the tissue culture process than traditional soil. |

what will be the blood group of of strings by the parents having the following genotype male a and female IO |
|
Answer» The IA allele gives TYPE A, IB gives type B, and IO gives type O. As both, IA and IB are dominant over IO, only IO/IO people have type O blood. Individuals with IA/IA or IA/IO have type A blood and individuals with IB/IB or IB/IO have type B. IA/IB people have both phenotypes because A and B express a special dominance relationship: codominance, which means that type A and B parents can have an AB child. A couple with type A and type B can also have a type O child if they are both heterozygous (IB/IO, IA/IO). So, the possible blood groups of the offspring of the parents with blood group O and AB are A and B because their parents' genotypes are IO/IO and IA/IB. So, under crossing, we get only A and B blood groups. |

Define dermal tissue |
|
Answer» Answer: The dermal TISSUE system protects the soft tissues of PLANTS and controls interactions with the plants' surroundings. The epidermis is a dermal tissue that is USUALLY a single layer of cells covering the younger PARTS of a plant. It secretes a WAXY layer called the cuticle that inhibits water loss.

Dfine thermal tissue |
|
Answer» Answer: As it was emphasized in the previous review article1, lasers are widely used in biology and medicine and the majority of the hospitals utilize modern laser systems for diagnostic and therapeutic APPLICATIONS. The medical laser applications are defined by the TYPE of interaction between laser light and TISSUES. Knowledge of laser-tissue interaction can help doctors or surgeons to select the optimal laser systems and to modify the type of their therapy1-3. Therefore, we seek to review the mechanisms of laser- tissue interaction. In reference number 1, the optical PROPERTIES of biological tissue such as absorption, scattering, penetration and fluorescence have been reviewed1. In this paper, we intend to study the thermal properties of the biological tissues. During all medical applications based on heating such as hair removal, cancer therapy or laser-induced interstitial thermotherapy (LITT), it is desirable to have a COMPLETE knowledge of temperature distribution in the tissue. Study of this temperature distribution requires knowledge about the thermal properties of biological tissues. The transportation of thermal energy in biological tissues is a complicated procedure including different phenomenological mechanisms such as thermal conduction, convection, radiation, metabolic activities and phase change2. If a biological tissue is illuminated by a laser light such as Neodymium-Doped Yttrium Aluminium Garnet (Nd:YAG) or Carbon Dioxide (CO2) laser, one can see multiple effects like coagulation, vaporization, carbonization or melting. These effects depend on the peak power and wavelength of the laser as well as the thermal properties of biological tissues |

Living tissue seen by which scientists at first? |
|
Answer» Answer: LIVE cell imaging is the study of living cells using time-lapse microscopy. It is used by scientists to obtain a better understanding of biological function through the study of cellular dynamics.[1] Live cell imaging was pioneered in first decade of the 20th century. One of the first time-lapse microcinematographic films of cells ever made was made by Julius RIES, showing the fertilization and development of the sea urchin egg.[2] SINCE then, several microscopy methods have been DEVELOPED which allow researchers to study living cells in greater detail with less effort. A newer type of imaging utilizing QUANTUM dots have been used as they are shown to be more stable.[3] The development of holotomographic microscopy has disregarded phototoxicity and other staining-derived disadvantages by implementing digital staining based on cells’ refractive index.

Define Some important functions of lymph ..... |
|
Answer» The lymphatic system the body’s SECONDARY circulatory system. Its functions are closely linked to the functions of the body’s primary circulatory system, the blood circulation. The key function of lymph is to transport blood components back to the blood stream and maintain the correct volume of blood circulation The INTERSTITIAL fluid plays an important role in giving shape and structure to the body organs, and in order to give each organ or body part the correct structure, the volume of interstitial fluid must remain constant.If interstitial fluid ACCUMULATES, swelling occurs and the shape and structure of the organ or body part changes. So although the lymphatic system is constantly absorbing interstitial fluid from the interstitial spaces, there is always a constant volume of interstitial fluid in a given interstitial space (except for example in TIMES of inflammation and swelling). The lymphatic system only absorbs fluid when new fluid is leaked into the space to replace that absorbed into the lymphatic system. Absorption of lymph into the lymphatic vessels plays an important role in maintaining the correct amount of fluid in the interstitial spaces to ensure that swelling does not occur. A considerable quantity of fluid leaks from the blood circulation each day. While the majority of leaked blood is reabsorbed by the blood vessels, up to 3 L per day remains in the spaces between tissues and becomes part of the interstitial fluid. Unless this fluid is absorbed by the lymphatic system, too much fluid will accumulate in the interstitial spaces and swelling will occur. # it maintains composition of tissue fluid &volume of blood. #it transports antibodies & lymphocytes to the blood . #keeps body cells moist . #transports oxygen ,hormones &nutrients to different parts of the body . # REMOVES metabolic waste from the cells. |

name the part of Rhizopus in which spores are formed.State the condition under which spores grow into a new individual. |
|
Answer» Answer: RHIZOPUS is a FUNGUS that reproduces by SPORE formation. The fungal hyphae give rise to a globular structure known as sporangium. This sporangium gives rise to several SPORES by repetitive division of its nucleus. Each nucleus gets SURROUNDED by a part of cytoplasm and, thus, develops into a spore. |
