What is dehydration?what is its role in seed dormancy? |
| Answer» Seed dormancy\xa0is\xa0defined\xa0as a state in which\xa0seeds\xa0are prevented from germinating even under environmental conditions normally favorable for germination. These conditions are a complex combination of water, light, temperature, gasses, mechanical restrictions,\xa0seed\xa0coats, and hormone structures.\xa0Seed dormancy\xa0allows\xa0seeds\xa0to overcome periods that are unfavourable for seedling established and is therefore\xa0important\xa0for plant ecology and agriculture. Several processes are known to be involved in the induction of\xa0dormancy\xa0and in the switch from the\xa0dormant\xa0to the germinating state. | |

Differentiate between Glycolisis and Fermentatio.. |
| Answer» Fermentation is a metabolic process that converts sugar (primarily glucose, fructose and sucrose) to acids, gases or alcohol. However, the sole energy extraction pathway is glycolysis plus one or two extra reactions. It is basically the Regeneration of NAD.\xa0Glycolysis is defined as an enzymatic breakdown of carbohydrates (as glucose) by way of phosphate derivatives with the production of pyruvic or lactic acid and energy stored in high-energy phosphate bonds of ATP.It is also known as “sweet splitting process.” It is a metabolic pathway that occurs in the ccytosol of cells in living organisms. This can either function in the presence or absence of oxygen. Therefore, it can be divided as aerobic and anaerobic glycolysis.Aerobic glycolysis yields more ATP than anaerobic process. With the presence of oxygen, it produces pyruvate and 2ATP molecules are produced as the net energy form.Anaerobic glycolysis is the only effective means of energy production during short, intense exercise providing energy for a period of 10 seconds to 12 minutes.The major difference is…Fermentation: Fermentation is a metabolic process that converts sugar into acids, gases or alcohol.Glycolysis: Glycolysis is an enzymatic breakdown of carbohydrates. | |

Difference between aeroponics And hydroponics |
| Answer» Aeroponics is the process of growing plants in an air or mist environment without the use of soil or an aggregate medium. The word "aeroponic" is derived from the Greek meanings of aer and ponos. Aeroponic culture differs from both conventional hydroponics, aquaponics, and in-vitro (plant tissue culture) growing. Unlike hydroponics, which uses a liquid nutrient solution as a growing medium and essential minerals to sustain plant growth, or aquaponics, which uses water and fish waste, aeroponics is conducted without a growing medium.It is sometimes considered[by whom?] a type of hydroponics, since water is used in aeroponics to transmit nutrients. | |

Where are ATP and NADPH used |
| Answer» ATP and NADPH act as energy driving factors in the biosynthetic phase (Calvin cycle) of photosynthesis. The Calvin cycle uses ATP and NADPH2 for the fixation and reduction of CO2 to form carbohydrates.Each Calvin cycle is completed in three phases—carboxylation, reduction and regeneration.During reduction or the glycolytic reversal phase, carbohydrate is formed at the expense of the photochemically made ATP and NADPH. Here, two molecules each of ATP and NADPH are required for fixing one molecule of CO2. | |

Why enzymes are in inactive form in our body? |
| Answer» Protein digesting enzymes are secreted in inactive form to protect the organs and glands from digestion by the enzymes. If they are released in active form, they start digesting the glands carrying them and the site where they are released. Therefore, they are released in inactive form and are activated only when proper condition is maintained such as presence of food and release of HCl. | |

Explain exchange of gases at alveoli level and tissue with help of suitable diagram |
| Answer» The function of respiratory system is to breathe in oxygen for respiration (producing energy from food), and to breathe out carbon dioxide produced by respiration.The major organs of respiratory system in human beings are: (i) Nose (ii) Nasal Passage (iii) Trachea (iv) Bronchi (v) Lungs and (vi) diaphragm.In human beings, air is taken into the body through the nostrils, is filtered by fine hairs that line the passage. When air passes through the nasal passage, the dust particles and other impurities present in it are trapped by nasal hair and mucus so that clean air goes into the lungs. From here, the air passes through the throat and into the lungs. Trachea does not collapse even when there is no air in it because it is supported by rings of soft bones called cartilage.Within the lungs, the passage divides into smaller and smaller tubes which finally terminate in balloon-like structures which are called alveoli. The alveoli provide a surface where the exchange of gases can take place. The walls of the alveoli contain an extensive network of blood-vessels. When we breathe in, the ribs are lift up and the diaphragm flattens which increases the size of the chest cavity. Because of this, air is sucked into the lungs and fills the expanded alveoli. The blood brings carbon dioxide from the rest of the body for release into the alveoli, and the oxygen in the alveolar air is taken up by blood in the alveolar blood vessels to be transported to all the cells in the body. During the breathing cycle, when air is taken in and let out, the lungs always contain a residual volume of air so that there is sufficient time for oxygen to be absorbed and for the carbon dioxide to be released. | |

Write a short note on kranz anatomy. |
| Answer» The word\xa0Kranz\xa0means “wreath” or “ring”.\xa0Kranz anatomy\xa0is a specialized structure in C4\xa0Plants where the mesophyll cells are clustered around the bundle-sheath cells in a ring-like fashion. The number of chloroplasts in the bundle-sheath cells is more than that in the mesophyll cells.\xa0The particularly large cells around the vascular bundles of the C4\xa0pathway plants are called bundle sheath cells, and the leaves which have such\xa0anatomy\xa0are said to have \'Kranz\'\xa0anatomy.\xa0Kranz\' means \'wreath\' and is a reflection of the arrangement of cells.\xa0It has been thought that a specialized leaf\xa0anatomy, composed of two, distinctive photosynthetic cell types (Kranz anatomy), is required for C4 photosynthesis. We provide evidence that C4 photosynthesis can function within a single photosynthetic cell in terrestrial plants. | |

How to find the genotype of blood grou? |
| Answer» A\xa0blood\xa0test is used to\xa0determine\xa0whether the A and/or B characteristics are present in a\xa0blood\xa0sample. It is not possible to\xa0determine\xa0the exact\xa0genotype\xa0from a\xa0blood\xa0test result of either\xa0type\xa0A or\xa0type\xa0B. If someone has\xa0blood type\xa0A, they must have at least one copy of the A allele, but they could have two copies.\xa0Their genotype is either AA or AO. Similarly, someone who is blood type B could have a genotype of either BB or BO.A blood test of either type AB or type O is more informative. Someone with blood type AB must have both the A and B alleles. The genotype must be AB. Someone with blood type O has neither the A nor the B allele. The genotype must be OO. | |

Features Important of pteridophytes |
| Answer» Pteridophytes display differentiation. The plant body can be divided into a true root, stem, and leaves. A saprophyte is the main plant body here. Some of the species belonging to this division have small leaves called as the microphylls. For example, Selaginella. Megaphylls are the large leaves that some pteridophytes have. For Example Fern plants. The main plant bears the sporangia. These bear some leaf-like appendages called the sporophylls. In a few species such as Selaginella and Equisetum, the sporophylls form compact structures called cones or strobili. | |

What are the essential conditions for growth of hydrophonic plants??? |
| Answer» In hydroponics, the plants mature in an inactive growing medium and an impeccably balanced pH with the nutrients delivered to the roots in an extremely soluble form. This permits the plant to carry its food with a very little exertion in contrast to the soil when the roots must grab the nutrients and obtain them. This is accurate even while making use of rich organic soil and premium nutrients. The energy exhausted by the roots in this procedure is the energy better expended on the vegetative development of flower and fruit production. | |

What do u mean by hypoxia..? |
| Answer» Hypoxia, in medicine, condition of the body in which the tissues are starved of oxygen. In its extreme form, where oxygen is entirely absent, the condition is called anoxia.There are four types of hypoxia:(1) the hypoxemic type, in which the oxygen pressure in the blood going to the tissues is too low to saturate the hemoglobin.(2) the anemic type, in which the amount of functional hemoglobin is too small, and hence the capacity of the blood to carry oxygen is too low.(3) the stagnant type, in which the blood is or may be normal but the flow of blood to the tissues is reduced or unevenly distributed.(4) the histotoxic type, in which the tissue cells are poisoned and are therefore unable to make proper use of oxygen. Diseases of the blood, the heart and circulation, and the lungs may all produce some form of hypoxia. | |
