How temprature and perance of light effect photosynthesis |
| Answer» The light\xa0intensity,\xa0carbon dioxide concentration, and temperature are the three main factors that impact photosynthesis. Greater\xa0light\xa0intensity leads to higher photosynthesis rates, as does increased\xa0carbon dioxide concentration.\xa0So in the case of a plant, a higher\xa0light intensity\xa0means more packets of\xa0light\xa0called “photons” are hitting the leaves. As you rise from low\xa0light intensity\xa0to higher\xa0light intensity, the\xa0rate of photosynthesis\xa0will\xa0increase\xa0because there is more\xa0light\xa0available to drive the reactions of\xa0photosynthesis.\xa0At medium\xa0temperatures, between 50 and 68 degrees Fahrenheit, or 10 and 20 degrees Celsius, the\xa0photosynthetic\xa0enzymes work at their optimum levels, so\xa0photosynthesis\xa0rates gauge high. Depending on the particular plant in question, set the greenhouse thermostat to a\xa0temperature\xa0within this range for best results. | |

Why do we need classification? |
|
Answer» To make our study easier , for naming an organism , to identify all of them in a easier way It is necessary to classify organisms because:\tClassification allows us to understand diversity better.\tIt helps in the identification of living organisms as well as in understanding the diversity of living organisms.\tClassification helps us to learn about different kinds of plants and animals, their features, similarities and differences.\tIt enables us to understand how complex organisms evolve from simpler organisms.\tTo understand and study the features, similarities and differences between different living organisms, they are grouped under different categories.\tClassification is a tool which helps us to deal with a great diversity of living forms.\tIt is essential to understand the inter-relationships among the different groups of organisms.\tClassification forms a base for the development of other biological sciences.\xa0 Because it allows the scientists to identify, group and Properly give a name to organisms... |

Explain GFR? |
| Answer» The mechanism by which the kidney regulates the glomerular filtration rate is autoregulative. It is carried out by the juxtaglomerular apparatus. Juxtaglomerular apparatus is a microscopic structure located between the vascular pole of the renal corpuscle and the returning distal convoluted tubule of the same nephron.It plays a role in regulating the renal blood flow and glomerular filtration rate. When there is a fall in the glomerular filtration rate, it activates the juxtaglomerular cells to release renin. This stimulates the glomerular blood flow, thereby bringing the GFR back to normal. Renin brings the GFR back to normal by the activation of the renin-angiotensin mechanism. | |

What are the functions of meristematic tissue |
| Answer» These tissues have the capability to develop by swift division. They assist in the major growth of the vegetation. Growth in length and growth in diameter of the plant are carried about by these cells. The Meristematic cells are cubical, living cells with a big nucleus. These cells are meticulously crammed with no intercellular spaces. Depending on the section where the meristematic tissues are existing, they are categorized as meristems intercalary, lateral and apical.\tApical meristem is existent at the growing tips or apical of stems and roots. Apical meristem upsurges the length of the plant.\tLateral meristem is existent in the radial portion of the stem or root. Lateral meristem upsurges the thickness of the plant.\tIntercalary meristem is found at the internodes or at the base of the leaves. Intercalary meristem upsurges the size of the internode. | |

Name the publication of Linnaeus |
|
Answer» He was a fater of classification , taxonomy , modern classification , modern ecology also. He briefly classified two kingdoms and also established a simple way of naming an organism called Bionomial Nomenclature Carl Linnaeus was a famous botanist, zoologist and a physician who brought about binomial nomenclature. Binomial nomenclature is a naming system in classification of species.He was famous for his different books published which laid foundation for nomenclature. He was known for two works namely Species Plantarum (1753) for plants and System Naturae (1758). These two books are still used in naming plants and animals. |

What is TCA cycle.write its role is in reputation |
| Answer» The\xa0tricarboxylic acid cycle\xa0(TCA cycle) is a series of enzyme-catalyzed chemical reactions that form a key part of aerobic respiration in cells. This\xa0cycle\xa0is also called the\xa0Krebs cycle\xa0and the\xa0citric acid cycle. This shows the\xa0TCA cycle\xa0in the context of what is happening in the inner mitochondrial membrane. The\xa0TCA cycle\xa0is\xa0amphibolic; i.e., it serves as a catabolic and an anabolic pathway. Reactions that utilize intermediates of the\xa0cycle\xa0as precursors for the biosynthesis of other molecules are as follows. This reaction takes place in the cytoplasm and is a source of acetyl-CoA for fatty acid biosynthesis. | |
| 6176. |
What is TCA cycle.write its role is in respiration.? |
| Answer» The TCA cycle\xa0is\xa0a\xa0central pathway into which many metabolites feed. It consists of\xa0a\xa0number of reactions which generate NADH and FADH₂ which can in turn be used by\xa0the oxidative phosphorylation\xa0pathway to generate ATP.\xa0The TCA cycle\xa0occurs in\xa0the\xa0matrix of\xa0the\xa0mitochondria.\xa0The\xa0citric acid cycle\xa0is a series of reactions that\xa0produces\xa0two carbon dioxide molecules, one GTP/ATP, and reduced forms of NADH and FADH2.\xa0The regulation of the rate of oxidative phosphorylation by the ADP level is called\xa0respiratory control\xa0or acceptor\xa0control. The level of ADP likewise affects the rate of the\xa0citric acid cycle\xa0because of its need for NAD+\xa0and FAD. The physiological significance of this regulatory mechanism is evident.\xa0The major significance of the citric acid cycle is to act as the final common pathway for the oxidation of carbohydrates, lipids and proteins, since\xa0glucose, fatty acids and many amino acids are all metabolised to acetyl CoA. | |

How to do nomenclature |
|
Answer» Nomenclature is a type of naming for living (bio related) organism.Mostly they are latin derived words.For doing this keep some points in your mind that1. Genus +species = scientific name.2. First word is always a genus and second is specie. 3. Always write them in italics or if you like to write them casually then you can underline them separately . 4. The first letter of genus should be capital and first word of species should be small. The scientific naming of an organism is called nomenclature. The system of scientific naming or nomenclature we use today was introduced by Carolus Linnaeus in the eighteenth century. In Binomial nomenclature, the first name is the generic name beginning with a capital letter whereas the second name is the species name which begins with a small letter. Example – Homo sapiens where Homo is a genus name and sapiens is a species name.\xa0Certain conventions are followed while writing the scientific names:1. The name of the genus begins with a capital letter.2. The name of the species begins with a small letter.3. When printed, the scientific name is given in italics.4. When written by hand, the genus name and the species name have to be underlined separately.\xa0 |

What is determinant growth |
| Answer» In biology and botany, indeterminate growth is growth that is not terminated in contrast to determinate growth that stops once a genetically pre-determined structure has completely formed. Duration and form of\xa0growth\xa0are the main ways to tell the\xa0difference between determinate and indeterminate\xa0tomatoes.\xa0Determinate\xa0or bush types bear a full crop all at once and top off at a specific height. ...\xa0Indeterminate\xa0varieties develop into vines that never top off and continue producing until killed by frost. | |

Explain the process of digestion in the buccal cavity with a note to the arrangement of teeth? |
| Answer» The process of digestion in the buccal cavity: The buccal cavity performs two major functions, mastication of food and facilitation of swallowing. The teeth and the tongue with the help of saliva masticate and mix up the food thoroughly. Mucus in saliva helps in lubricating and adhering the masticated food particles into a bolus. The bolus is then conveyed into the pharynx and then into the oesophagus by swallowing or deglutition. The bolus further passes down through the oesophagus by successive waves of muscular contractions called peristalsis. The gastro-oesophageal sphincter controls the passage of food into the stomach. The saliva secreted into the oral cavity contains electrolytes and enzymes, salivary amylase and lysozyme. The chemical process of digestion is initiated in the oral cavity by the hydrolytic action of the carbohydrate splitting enzyme, the salivary amylase. About% of starch is hydrolysed here by this enzyme (optimum pH 6.8) into a disaccharide-maltose. Lysozyme present in saliva acts as an antibacterial agent that prevents infections. | |

The mycelium is aseptate and coenocytic.Explain? |
| Answer» Filamentous fungi may contain multiple nuclei in a coenocytic mycelium. A coenocyte functions as a single coordinated unit composed of multiple cells linked structurally and functionally, i.e. through gap junctions. Fungal mycelia in which hyphae lack septa are known as "aseptate" or "coenocytic". | |
| 6189. |
Explain the different types of INFLORESCENCE?With Examples. |
| Answer» Inflorescence is the manner in which the flowers are arranged on the flowering axis. During the flowering season, the vegetative apex of the stem gets converted into a floral meristem. Based on whether the floral axis continues to grow or end in a flower, inflorescence is classified into racemose and cymose. In racemose inflorescence, the floral axis continues to grow and produces flowers laterally. On the other hand, in cymose inflorescence, the main axis terminates into a flower. Hence, it is limited in growth. | |

What is taxo |
|
Answer» Gud Question ✌️ Taxonomy is the science of naming, describing and classifying organisms and includes all plants, animals and microorganisms of the world. axonomy is the science of naming, describing and classifying organisms and includes all plants, animals and microorganisms of the world. Using morphological, behavioural, genetic and biochemical observations, taxonomists identify, describe and arrange species into classifications, including those that are new to science. Taxonomy identifies and enumerates the components of biological diversity providing basic knowledge underpinning management and implementation of the Convention on Biological Diversity. Unfortunately, taxonomic knowledge is far from complete. In the past 250 years of research, taxonomists have named about 1.78 million species of animals, plants and micro-organisms, yet the total number of species is unknown and probably between 5 and 30 million.\xa0 |
