Explain c3 cycle |
| Answer» The Calvin cycle can be described under three stages: carboxylation, reduction and regeneration.Carboxylation: Fixation of CO2 into a stable organic intermediate is called carboxylation. In this step, carbon dioxide is utilised for the carboxylation of RuBP. The enzyme RuBP carboxylase catalyses this reaction. The reaction results in the formation of two molecules of 3-PGA. This enzyme is also called RuBP carboxylase-oxygenase or RuBisCO; because it also has an oxygenation activity.Reduction: This step involves utilization of 2 molecules of ATP for phosphorylation and two of NADPH for reduction of each CO2 molecule fixed. For the removal of one molecule of glucose from the pathway, fixation of six molecules of CO2 and 6 turns of the cycle are required.Regeneration: This step involves regeneration of CO2 acceptor molecule RuBP. This is necessary for the cycle to continue without interruption. This step requires one ATP for phosphorylation to form RuBP.\xa0 | |

Which organ of alimentary canal absent in transverse section of alimentary canal Plz tell me |
| Answer» The\xa0liver\xa0(under the ribcage in the right upper part of the abdomen), the\xa0gallbladder\xa0(hidden just below the liver), and the\xa0pancreas\xa0(beneath the stomach) are not part of the alimentary canal, but these organs are essential to digestion.The liver makes\xa0bile, which helps the body absorb fat. Bile is stored in the gallbladder until it is needed. The pancreas makes enzymes that help digest proteins, fats, and carbs. It also makes a substance that neutralizes stomach acid. These enzymes and bile travel through special pathways (called ducts) into the small intestine, where they help to break down food. The liver also helps process nutrients in the bloodstream. | |

what is isotropic and anisotrooic |
|
Answer» In mathematics, catastrophe theory is a branch of bifurcation theory in the study of dynamical systems; it is also a particular special case of more general singularity theory in geometry. When the properties of a material vary with different crystallographic orientations, the material is said to be anisotropic. Alternately, when the properties of a material are the same in all directions, the material is said to be isotropic Isotropic refers to the properties of a material which is independent of the direction whereas anisotropic is direction-dependent. These two terms are used to explain the properties of the material in basic crystallography. The mechanical and physical properties can be easily affected based on the atom orientation in crystals. Some examples of isotropic materials are cubic symmetry crystals, glass, etc. Some examples of anisotropic materials are composite materials, wood, etc. |

Cork cambium forms tissue that form cork .do you agree with statement explain |
| Answer» The\xa0cork cambium\xa0is a lateral meristem and is responsible for secondary growth that replaces the epidermis in roots and stems. Synonyms for\xa0cork cambium\xa0are bark\xa0cambium, pericambium and phellogen. Phellogen is defined as the meristematic cell layer responsible for the development of the periderm. As growth proceeds, the cork cambium forms in living\xa0cells\xa0of the\xa0epidermis,\xa0cortex, or, in some plants,\xa0phloem\xa0and produces a secondary protective tissue, the\xa0periderm. The cork cambium is, like the vascular cambium, a lateral\xa0meristem\xa0that produces\xa0cells\xa0internally and externally by tangential divisions.\xa0Yes, cork cambium forms tissues that form cork. AS the stem continues to increase in girth another\xa0meristematic\xa0tissue called cork cambium or phellogen develops in\xa0cortex\xa0region of stem. The phellogen cuts off cells on both sides. The outer cells differentiate into cork or phellem. | |

Salivary glands are made up of which tissue? |
| Answer» All salivary glands follow a similar development pattern. The functional glandular tissue (parenchyma) develops as an epithelial outgrowth (glandular bud) of the buccal\xa0epithelium\xa0that invades the underlying\xa0mesenchyme. The\xa0connective tissue\xa0stroma (capsule and septa) and\xa0blood vessels\xa0form from the\xa0mesenchyme.\xa0The parotid salivary glands, the largest of the three, are located between the ear and ascending branch of the lower jaw. Each gland is enclosed in a tissue capsule and is composed of fat tissue and\xa0cells\xa0that secrete mainly serous fluids. | |

Why do some plants like Hibiscus plants does not bear fruit even though there is pollination? |
| Answer» Hibiscus can self-pollinate. In other words, pollen from the male parts of the flower ca\xa0pollinate\xa0the female parts of that same blossom. ... If the flower is\xa0pollinated, a seed pod\xa0will\xa0develop. The ovary at the base of the flower\xa0will\xa0swell. The\xa0hibiscus does not bear fruits\xa0because the androecium and gynoecium\xa0are not\xa0working. Explanation: The\xa0hibiscus fruits\xa0have a five-lobed pod or capsule just below the flower, the lob contains seeds\xa0like\xa0all other\xa0plants. They\xa0are no\xa0distinct\xa0fruits. | |

Write the lo, write the location structure and function of testis and ovary |
| Answer» The\xa0testes\xa0are the male gonads. Like the\xa0ovaries, the\xa0testes\xa0are paired organs, but unlike the\xa0ovaries, the\xa0testes\xa0are found outside the pelvic cavity and are contained in the scrotal sac. The\xa0testes\xa0are the organs that produce sperm, which is the male reproductive cell.\xa0The gonads, the primary reproductive organs, are the testes in the male and the ovaries in the female. These organs are responsible for producing the sperm and ova, but they also secrete\xa0hormones\xa0and are considered to be\xa0endocrine\xa0glands.\xa0The testicles are housed in the\xa0*******\xa0just behind the *****. The testicles are the male gonads — the primary male reproductive organs. They have two, very important functions that are very important to the male\xa0reproductive system: they produce gametes or sperm, and they secrete\xa0hormones, primarily testosterone. | |

What are ammonotelic urotellic and urecotellic |
|
Answer» 1. Uricotelic - The organisms that excrete nitrogenous wastes as uric acid in the form of pellet or paste with a minimum loss of water are called uricotelic animals. Fr examples, Birds that cannot afford to loose water like humans or fishes, therefore they have developed a mechanism to excrete waste loosing least amount of water. Uric acid is only a little soluble in water and hence can be excreted by loosing only a small amount of water.2.Ammonotelic - Those organisms which excrete nitrogenous wastes in the form of ammonia are called as ammonotelic. Ammonia is highly soluble in water and for its elimination a lot of water is required. Aquatic animals live in abundance of water and can afford to loose a lot of water as they would gain it very easily. So, aquatic animals are ammonotelic.\xa03. Ureotelic - Ureotelic animals are animals that excreate nitrogeenous wastes in the form of urea are called ureotelic. Urea requires less water to be eliminated than ammonia and hence it has become a feature of terrestrial animals like huumans. The organisms that excrete wastes in the form of ammonia are ammonotelic, urea-urotellic, uric acid-uricotellic. |

Royal deases of England |
| Answer» Hemophilia is sometimes referred to as “the\xa0royal disease,” because it affected the\xa0royal\xa0families of\xa0England, Germany, Russia and Spain in the 19th\xa0and 20th\xa0centuries. Queen Victoria of\xa0England, who ruled from 1837-1901, is believed to have been the carrier of hemophilia B, or factor IX deficiency.\xa0She passed the trait on to three of her nine children. Her son Leopold died of a hemorrhage after a fall when he was 30. Her daughters Alice and Beatrice passed it on to several of their children. Alice’s daughter Alix married Tsar Nicholas of Russia, whose son Alexei had hemophilia. Their family’s entanglement with Rasputin, the Russian mystic, and their deaths during the Bolshevik Revolution have been chronicled in several books and films. Hemophilia was carried through various royal family members for three generations after Victoria, then disappeared. | |
